Questions and answers

Short answers to the questions readers ask most. Each one links to the page that explains it in full, with sources.

Buying and safety

Does 'Official Store' on AliExpress mean the brand runs it?

Not by itself. The strongest sign is a link from the brand's own website, as QUICKO provides for its store. A store named 'KSGER Official Store' exists, but we found no KSGER-controlled website that confirms it. More in Buying repair tools: voltage, marks and imports

Is CE marking a safety approval?

No. The European Commission says CE marking is the manufacturer's declaration that a product meets EU requirements and does not mean the EU or any other authority has approved it as safe. More in Buying repair tools: voltage, marks and imports

Is a UL or ETL listing required by law for a soldering station?

OSHA says its authority is limited to employers and that it does not require manufacturers or suppliers to have products certified by a recognized lab. A genuine listing is evidence of safety testing, not a legal minimum. More in Buying repair tools: voltage, marks and imports

Do I pay import duty on AliExpress orders to the US?

Applicable duties, taxes and fees now apply whatever the order value. Duty-free de minimis treatment has been suspended for all countries since August 29, 2025, and 2026 CBP rules extended the suspension to every shipping mode, including mail. More in Buying repair tools: voltage, marks and imports

What is the Canadian duty-free limit for AliExpress parcels?

For goods from countries outside CUSMA, such as China, the CBSA says duty and tax relief applies only up to CAD 20. The higher CAD 150 duty and CAD 40 tax levels are for qualifying courier shipments from the US or Mexico. More in Buying repair tools: voltage, marks and imports

Can I return a tool bought on AliExpress?

AliExpress's Free Return terms apply only to items with the Free Return label: you must request the return within 15 calendar days, and the item must be unused and in its original packaging. Check the label on the listing before you order. More in Buying repair tools: voltage, marks and imports

Is a '110 V' soldering station right for a 120 V outlet?

Yes, if that is its rated input. The US Department of Energy describes US household power as 110-120 V at 60 Hz, so a variant labeled 110 V, 120 V or 110-120 V is the one to choose. Check the rating printed on the unit when it arrives. More in AliExpress soldering station buyer's checklist

Can I use a 220 V soldering station with a plug adapter?

Do not plan on it; buy the 110-120 V variant. Makers that sell in both markets publish separate mains versions, such as Weller's 120 V and 230 V WE1010 kits and JBC's CD-1BQF (120 V) and CD-2BQF (230 V) stations. More in AliExpress soldering station buyer's checklist

Does an FCC or CE mark mean a station is electrically safe?

No. CE is the manufacturer's own declaration for EU law, and FCC authorization concerns radio-frequency interference. For safety testing, look for a recognized lab's mark, such as ETL, that you can find in the lab's directory. More in AliExpress soldering station buyer's checklist

Are Hakko or JBC parts sold on AliExpress genuine?

Do not assume so. American Hakko tells buyers to use authorized distributors and warns that counterfeits can carry its logo. We found no JBC statement about marketplace sellers, so we treat such parts as compatible, not genuine. More in AliExpress soldering station buyer's checklist

Will I pay duty on an AliExpress order to the US?

Applicable duties, taxes and fees are owed whatever the order value. De minimis treatment has been suspended for all countries since August 29, 2025, and 2026 CBP rules extended the suspension to every shipping mode, including mail. More in AliExpress soldering station buyer's checklist

How long do I have to return an AliExpress item?

For items with the Free Return label, AliExpress's terms give 15 calendar days to request a return, and the item must be unused and in its original packaging. For other items, check the return terms shown on the listing before you order. More in AliExpress soldering station buyer's checklist

Is ETL as good as UL?

Both are certification marks from labs on OSHA's list of Nationally Recognized Testing Laboratories: UL LLC, and Intertek, which runs ETL. Intertek says its ETL mark shows a product was independently tested and certified to applicable safety standards. More in UL, ETL, CE and FCC marks explained

Does a CE mark mean a product is safe?

No. The European Commission says CE marking is the manufacturer's declaration that a product meets EU requirements, and that it does not mean the EU or any other authority approved it as safe. More in UL, ETL, CE and FCC marks explained

Does an FCC logo mean a soldering station is electrically safe?

No. FCC equipment authorization is about radio-frequency interference and RF exposure; it does not address shock or fire safety. More in UL, ETL, CE and FCC marks explained

Is UL certification required by law?

Not by OSHA for tools you buy for home use: OSHA's authority is limited to employers, and it says it does not require manufacturers to have products certified by an NRTL. Other rules may apply where you live or work. More in UL, ETL, CE and FCC marks explained

How can I check whether a UL or ETL mark is real?

Note the model and the certifier, then look it up: Intertek runs a public Directory of Listed Products for ETL. For other marks, ask the seller for the certificate or file number and confirm it with the lab. More in UL, ETL, CE and FCC marks explained

Desoldering

Solder wick or a solder pump: which should I buy first?

Both, if you can. SparkFun recommends a solder vacuum for clearing solder left behind in through-holes, while wick soaks up solder from pads and bridges. More in Desoldering tools: wick, pumps and guns

Why is my solder wick not picking up solder?

Check heat and flux first: the braid has to get hot enough for solder to flow into it, and fresh flux helps, since iFixit notes that braid usually carries only dry flux. See how to use solder wick. More in Desoldering tools: wick, pumps and guns

When is a desoldering gun worth buying?

When you remove many multi-pin through-hole parts, as in recaps and restorations. A gun such as Hakko's FR-301 heats the joint through its nozzle and pulls the solder away with built-in suction, rated 11 liters per minute on the Japanese model. More in Desoldering tools: wick, pumps and guns

Does a desoldering gun need a grounded plug?

For static-sensitive work, choose one that has one. Hakko Japan sells the FR-301 with a three-conductor plug, grounded to prevent electrostatic damage to components, or with a two-conductor plug. More in Desoldering tools: wick, pumps and guns

Why won't my solder wick soak up solder?

Usually too little heat is reaching the solder through the braid, or there is too little flux. Add flux, move to a fresh section of braid and press a larger, tinned tip flat on top of the braid over the solder. More in How to use solder wick

Should I use solder wick or a desoldering pump?

Use wick for flat jobs such as pads and bridges, and a pump to clear solder out of through-holes; SparkFun calls a solder vacuum a great tool for that job. More in How to use solder wick

Do I need extra flux if the braid is already fluxed?

It often helps. iFixit notes that braid usually has dry flux applied, but adding a little fresh flux to the joint is the first thing to try when the braid won't take solder. More in How to use solder wick

What width of solder wick should I buy?

Pick braid about as wide as the pads you clear most often. A narrow roll for fine-pitch surface-mount work and a wider one for through-hole pads covers most benches. More in How to use solder wick

Can solder wick lift a pad?

Yes, if braid that has cooled onto the pad is pulled away, or if you scrub with it under pressure. Lift the braid and iron together while the solder is still molten; Adafruit describes a lifted pad as one that has come away from the board. More in How to use solder wick

ESD and bench safety

Do I need an ESD mat for home electronics repair?

If you handle bare boards and chips, it is a sensible precaution. ESDA notes that many components are susceptible to discharges below 100 V and that ESD can leave latent defects that show up later. More in ESD and bench safety

How do I ground an ESD mat at home?

Through a common-point ground. ESDA's preferred connection runs from the common point ground to the equipment grounding conductor, the third wire of a grounded outlet. Follow the mat maker's instructions and never improvise a connection. More in ESD and bench safety

What resistor should an ESD wrist strap have?

ESDA says the cord resistor is most commonly one megohm, rated at least 1/4 watt with a working voltage rating of 250 V. More in ESD and bench safety

Can I wear a wrist strap while working on mains equipment?

No. ESDA says wrist straps must not be used if the operator will be exposed to electrical circuits of 250 V or higher. More in ESD and bench safety

Is a soldering station with a two-prong plug ESD-safe?

Do not assume so. Look for published tip-to-ground figures, such as the under 2 ohms and under 2 mV that Hakko and JBC give for their stations, and prefer a grounded three-prong plug. More in ESD and bench safety

How do I dispose of an old lithium-ion battery?

Not in household trash or recycling. The EPA says to take it to battery recycling or household hazardous waste collection, with the terminals taped or the battery bagged, and to contact the maker if it is damaged. More in ESD and bench safety

How do I ground an ESD mat at home?

Connect the mat's ground cord to a common point ground that ties into the outlet's equipment ground (the third wire), which the ESD Association describes as the preferred connection. Use a ground cord or plug made for ESD mats rather than an improvised wire. More in How to set up an ESD-safe bench

What resistor should an ESD wrist strap have?

The ESD Association says the cord resistor is most commonly one megohm, rated at least 1/4 watt with a 250-volt working voltage. More in How to set up an ESD-safe bench

Is a silicone soldering mat ESD-safe?

Not unless its maker states a resistance to ground in the ESD range. The ESD Association puts ESD worksurfaces at 1.0 x 10^6 to 1.0 x 10^9 ohms to ground; heat resistance is a different property. More in How to set up an ESD-safe bench

Should I wear a wrist strap when working on mains?

No. The ESD Association says wrist straps must not be used if you will be exposed to circuits of 250 volts or higher. More in How to set up an ESD-safe bench

Do I really need ESD protection for hobby repair?

If you handle bare boards and chips, it is simple insurance. The ESD Association notes that many components are susceptible to discharges below 100 V and that damage can be latent, showing up only later. More in How to set up an ESD-safe bench

Fume extraction

Do I need a fume extractor for hobby soldering?

If you solder indoors regularly, plan for one. The UK's Health and Safety Executive lists rosin flux fume as a top cause of occupational asthma and advises extracting the fume and keeping your head out of the plume. More in Solder fume extraction

Is a small carbon-filter fan enough?

Not on its own. The HSE says bench-mounted boxes are of limited use unless fitted with a HEPA filter, and the EPA says activated carbon is effective only when a large amount of it is used. More in Solder fume extraction

What does a HEPA filter remove from solder fume?

Particles. Hakko rates the HEPA filter in its FA-430 extractor at 99.97% at 0.3 µm on its low and medium settings. Gases need a gas-removal stage, such as activated carbon, according to the EPA. More in Solder fume extraction

Does a fume extractor replace ventilation?

No. The EPA's guidance on air cleaners says filtration does not replace the need to control pollutants and ventilate. More in Solder fume extraction

Is on-tip fume extraction a good idea?

It captures fume right at the tip, but the HSE notes that on-tip extraction blocks up quickly and needs frequent cleaning. More in Solder fume extraction

Does a HEPA filter remove solder fumes?

A HEPA filter targets particles, which make up the visible smoke. EPA notes that most filters handle either particles or gases, so removing gases takes an activated-carbon or other gas-removal filter as well. More in Solder smoke absorber vs fume extractor

Is a carbon-filter fan enough for soldering?

Not on its own. EPA says activated carbon can be effective only when a large amount is used, and HSE says bench-mounted boxes are of limited use unless fitted with a HEPA filter. More in Solder smoke absorber vs fume extractor

Are solder fumes dangerous?

Rosin flux fume is a recognized hazard: the UK Health and Safety Executive calls it a top cause of occupational asthma and advises extracting it at the source. More in Solder smoke absorber vs fume extractor

Is an open window enough ventilation for soldering?

It helps, but it does not capture the plume in front of your face. EPA says filtration does not replace ventilation, and HSE prefers extraction at the source, so if you solder often, use both. More in Solder smoke absorber vs fume extractor

What specs should a fume extractor publish?

At least the filter type and efficiency, airflow and static pressure. Hakko's FA-430, for example, lists 1,500 Pa static pressure, up to 145 cfm with one duct and 99.97% HEPA efficiency at 0.3 µm. More in Solder smoke absorber vs fume extractor

Meters, supplies and scopes

CAT II or CAT III for electronics repair?

Choose for the highest category you will actually measure. Fluke places appliances and portable tools plugged into outlets in CAT II, and building distribution and fixed equipment such as switchgear in CAT III. More in Meters, bench supplies and oscilloscopes

Is a CAT rating printed on a cheap meter enough?

Not on its own. Fluke says test tools should be independently evaluated and certified; look for the mark of a recognized lab such as UL, CSA, TUV or Intertek's ETL, and check the lab's listing directory where it has one. More in Meters, bench supplies and oscilloscopes

How much oscilloscope bandwidth do I need?

Tektronix suggests at least five times the highest frequency component you need to see. Keysight suggests at least 3x for analog sine waves and 5x the clock rate for digital signals. More in Meters, bench supplies and oscilloscopes

What should a bench power supply have for repair work?

An adjustable current limit, over-voltage and over-current protection that switch the output off, as on Rigol's DP700 series, and published noise figures. More in Meters, bench supplies and oscilloscopes

Are FNIRSI oscilloscopes as fast as advertised?

We cannot confirm it. FNIRSI claims 100 MHz and 1 GS/s for its 1014D, but EEVblog users dispute some FNIRSI headline specs, one estimating about 30 MHz of real bandwidth for a FNIRSI scope. No independent measurement was found. More in Meters, bench supplies and oscilloscopes

Should I buy an oscilloscope or a multimeter first?

A multimeter. It answers the first questions in most repairs, such as whether power is present and whether something is shorted; a scope comes next, when you need to see a signal over time. More in Do you need an oscilloscope?

How much oscilloscope bandwidth do I need?

Use a rule with headroom: Keysight suggests at least three times the highest sine frequency for analog signals and five times the highest clock rate for digital ones, and Tektronix's five-times rule keeps amplitude error within about 2%. More in Do you need an oscilloscope?

Is 1 GSa/s enough sample rate?

It depends on the bandwidth. Keysight suggests a maximum sample rate of at least four to five times the scope's bandwidth, so on that rule 1 GSa/s suits a scope of up to about 200 to 250 MHz. More in Do you need an oscilloscope?

Are budget handheld oscilloscopes accurate?

Treat their headline figures as claims. FNIRSI lists 100 MHz for its 1014D, while EEVblog forum users dispute FNIRSI's headline specs, one estimating about 30 MHz of real bandwidth for a FNIRSI model. More in Do you need an oscilloscope?

Can I measure mains with an oscilloscope?

Not with an ordinary setup. Only use a scope on mains-powered circuits if the scope, its probes and your method are rated for it; Fluke notes that higher measurement categories carry higher-energy transients and that test tools should be independently certified. More in Do you need an oscilloscope?

What does current limiting do on a bench power supply?

It caps the current the supply will deliver. When a load tries to draw more, the supply holds the current at your limit and lets the voltage fall, which stops a shorted board from drawing everything the supply can give. More in How to use a bench power supply

What is the difference between a current limit and OCP?

A current limit keeps the output on at the set current. OCP switches the output off when current passes a threshold; Rigol's DP700 series, for example, has user-set OVP and OCP that turn the output off. More in How to use a bench power supply

Is a 30 V 5 A bench supply enough for repair?

It depends on your devices, so check the highest voltage and current they need. As a reference, Rigol's DP711 is a 30 V / 5 A model, while its DP712 trades current for voltage at 50 V / 3 A. More in How to use a bench power supply

Can I power a phone board from a bench supply?

Follow the device's repair guide first, starting with its battery steps. In its ROG Ally battery guide, iFixit says to drain the battery below 25% before starting, because a charged lithium-ion battery can catch fire if damaged. More in How to use a bench power supply

Why does my supply go into CC mode as soon as I switch on?

The board is trying to draw more than your current limit. On a board that should draw little, that usually points to a short: switch off and investigate before you raise the limit. More in How to use a bench power supply

Do I need CAT II or CAT III for electronics repair?

For equipment that plugs into an outlet, CAT II is the matching category; Fluke places distribution wiring and fixed installations in CAT III. If the same meter might ever be used on building wiring, choose the higher category. More in Multimeter CAT ratings explained

Does a CAT rating matter for battery-powered boards?

Less, because those circuits are not connected to mains. It matters the moment the same meter is used on anything plugged into an outlet. More in Multimeter CAT ratings explained

Can I trust a CAT rating printed on a budget meter?

Not by itself. Fluke says test tools should be independently evaluated and certified by labs such as CSA, UL, TÜV or Intertek (ETL); look for one of those marks and check the listing with the certifier. More in Multimeter CAT ratings explained

What standard covers multimeter safety?

IEC 61010-2-033. Its third edition, published in 2023, covers hand-held multimeters for domestic and professional use that can measure mains voltage. More in Multimeter CAT ratings explained

Do test leads need a CAT rating too?

Check them as well: use leads marked for at least the same category and voltage as your measurement, and replace any with damaged insulation. More in Multimeter CAT ratings explained

Magnification

Is 1200X magnification useful for soldering?

The figure tells you little on its own. Digital magnification depends on the screen: Andonstar, for example, quotes up to 300x for its AD409 on a 27-inch monitor. Compare working distance and field of view instead. More in Microscopes for soldering

What is working distance on a microscope?

The space between the lens and the board, where your iron and tweezers have to fit. AmScope quotes 200 mm (8 in) for its SM-6TZ stereo microscope. More in Microscopes for soldering

Digital or stereo microscope for soldering?

Digital is easier for sharing and recording; stereo gives natural depth. EEVblog users report display lag and a lack of depth as drawbacks of digital models, though at least one Andonstar owner noticed no lag. These are owner reports, not measurements. More in Microscopes for soldering

What does a Barlow lens do?

It changes magnification and working distance together. AmScope says its 0.5X Barlow lens halves magnification and doubles the working distance and field of view. More in Microscopes for soldering

Do I need a microscope for SMD soldering?

It becomes more useful as parts get smaller. JBC describes its smallest C115 cartridges as made for very small components, even under a microscope. More in Microscopes for soldering

Is a digital microscope good enough for soldering?

For inspection and occasional surface-mount work, it can be. For long soldering sessions, EEVblog forum users flag screen delay and the lack of stereo depth as drawbacks, though one Andonstar owner reported no noticeable delay. More in Digital vs stereo microscope for soldering

Is the Andonstar AD409 a 4K microscope?

No. Andonstar labels its top HDMI mode UHD 2880x2160 at 24 fps; 4K UHD is 3840x2160. More in Digital vs stereo microscope for soldering

What does trinocular mean on a microscope?

A stereo head with a third port for a camera, so you can look through the eyepieces and record at the same time. AmScope's SM-6TZ is one example. More in Digital vs stereo microscope for soldering

How much working distance do I need for soldering?

Enough to fit your iron and tweezers at a comfortable angle; EEVblog users single out working height as a practical need. As a reference, AmScope advertises 200 mm (8 in) for its SM-6TZ; the figure changes with the Barlow lens fitted. More in Digital vs stereo microscope for soldering

Can I add a camera to a stereo microscope later?

Plan for it when you buy: a trinocular head has a dedicated camera port, as on AmScope's SM-6TZ, while a binocular head has no third port. More in Digital vs stereo microscope for soldering

What does 1200X mean on a digital microscope?

Usually how large the image looks on some screen, not an optical figure. Without the screen size, working distance and field of view it cannot be compared; Andonstar, for example, quotes up to 300x for its AD409 on a 27-inch monitor. More in Microscope magnification explained

What magnification do I need for SMD soldering?

There is no single number. Use the lowest magnification at which you can see the joint clearly, so you keep a wide view and room for tools, and zoom in only to inspect. More in Microscope magnification explained

What does a 0.5X Barlow lens do?

AmScope says its 0.5X Barlow lens halves magnification and doubles the working distance and field of view, which gives you more room for an iron under the lens. More in Microscope magnification explained

Can I compare digital and optical magnification?

No. Optical magnification comes from the lenses; a digital figure depends on the display it is viewed on, which is why Andonstar ties its 300x figure to a 27-inch monitor. More in Microscope magnification explained

What is working distance on a microscope?

The gap between the lens and the board when the image is in focus. It is the space your iron and tweezers have to fit into, so for soldering it matters more than extra magnification. More in Microscope magnification explained

Hot air and rework

Can I use a 220 V hot-air station in the US?

Choose a 110-120 V variant instead. YIHUA's page for the 959D and QUICK's page for the 861DW list 220 V input only, so check that the exact variant you select is a 110 V one before you pay. More in Hot-air rework stations and preheaters

Is a higher airflow number better on a hot-air station?

The numbers often do not compare. YIHUA rates the 959D at up to 120 liters per minute, while QUICK describes the 861DW's airflow as a 1-120 step scale rather than a flow rate. More in Hot-air rework stations and preheaters

Do I need a PCB preheater?

Not for a first bench. Preheaters are made for boards that soak up heat: Hakko positions its FR-830 for multilayer boards and recommends its FR-872 for lead-free work. More in do you need a PCB preheater? More in Hot-air rework stations and preheaters

Should I drain a phone battery before hot-air work?

Follow your device's repair guide. iFixit's ROG Ally battery guide, for example, says to drain the battery below 25% before starting, because a charged lithium-ion battery may catch fire if damaged. More in Hot-air rework stations and preheaters

Is there an industry standard for electronics rework?

Yes. IPC lists IPC-7711/21D, Rework, Modification and Repair of Electronic Assemblies, among its 2024 releases. More in Hot-air rework stations and preheaters

What does a PCB preheater do?

It warms the whole board, usually from below, so the iron or hot air has less heat to add at the joint. Hakko describes its FR-830 hot-air preheater as best suited for multilayer boards. More in Do you need a PCB preheater?

Do I need a preheater for phone repair?

Not to start. Treat it as an upgrade after hot air, magnification and a precision iron; it matters most when a large or heavy board will not come up to temperature with hot air alone. More in Do you need a PCB preheater?

Can a preheater replace a hot-air station?

Treat it as a helper, not a replacement. It warms the whole board; you still need hot air or an iron to work on the part itself. See the hot-air station buying guide. More in Do you need a PCB preheater?

What size preheater do I need?

One whose heated area covers your largest board. As a reference, Hakko's FR-872 takes boards up to 330 x 250 mm and has four separately switched zones. More in Do you need a PCB preheater?

Why is lead-free rework harder?

Lead-free alloys melt hotter: Kester lists SAC305 at 217-220 °C against 183 °C for Sn63Pb37. Hakko recommends its FR-872 preheater for lead-free work. More in Do you need a PCB preheater?

Can I use a 220 V hot-air station in the US with a plug adapter?

No. A plug adapter changes the shape of the plug, not the voltage. US outlets supply 110-120 V at 60 Hz, so buy the variant made for that, labeled 110 V or 110-120 V. More in Hot-air rework station buying guide

Are hot-air station airflow numbers comparable between brands?

Not reliably. YIHUA states up to 120 L/min for its 959D, while QUICK's 861DW uses a 1-120 scale of adjustment steps, so similar-looking numbers mean different things. More in Hot-air rework station buying guide

Do I need hot air if I only solder through-hole parts?

Usually not. Hot air melts every joint of a surface-mount part, connector or shield at once; for through-hole work, start with an iron, flux and a desoldering method such as solder wick. More in Hot-air rework station buying guide

Is a 2-in-1 soldering and hot-air station a good idea?

It saves space and an outlet, but both tools share one box, so a fault or an upgrade affects both. Judge it on the exact voltage variant, controls and nozzles, not on the number of functions. More in Hot-air rework station buying guide

How long does a hot-air station take to heat up?

It varies by model. In Tom's Hardware's own timing of one unit, the YIHUA 995D+ hot-air handle took 92 seconds to reach working temperature, against 24 seconds for the same station's iron. More in Hot-air rework station buying guide

Solder and flux

What is the difference between 63/37 and 60/40 solder?

Kester lists 63/37 as melting at a single temperature, 183°C (361°F), because it is eutectic, while 60/40 melts over a range from 183 to 190°C (361-374°F). More in Solder and flux for electronics

Is lead-free solder harder to use?

Usually, yes. iFixit says tin-silver-copper alloys such as SAC305 are harder to work with because of poorer wetting and a wider melting range, and Kester lists SAC305 at 217-220°C against 183°C for 63/37. More in Solder and flux for electronics

Do I need to clean flux residue off the board?

It depends on the flux. SparkFun says to remove water-soluble flux residue and that no-clean residue does not need removing. Kester says rosin residue can normally stay, unless the assembly runs above 200°F. More in Solder and flux for electronics

Can I use plumbing or acid-core solder on electronics?

No. Canfield, a solder maker, says acid-core solder is not recommended for electrical or electronic work because its residue is corrosive. More in Solder and flux for electronics

What temperature should I set my iron to?

There is no single answer. SparkFun teaches 325-375°C as a starting range, and Adafruit suggests 370°C for 60/40 solder and 400°C for lead-free. Check your solder maker's data sheet as well. More in Solder and flux for electronics

Are solder fumes harmful?

Rosin flux fume can be. The UK's Health and Safety Executive lists rosin-based solder flux fume as a top cause of occupational asthma and advises extraction at the source and keeping your head out of the plume. More in Solder and flux for electronics

Is 63/37 solder better than 60/40?

For hand soldering it is easier to control: 63/37 is eutectic and sets at a single 183 °C, while 60/40 passes through a 183–190 °C pasty range. Both contain lead and need the same hygiene. More in 63/37 vs 60/40 vs SAC305 solder

What temperature should I use for SAC305?

Adafruit suggests about 400 °C (750 °F) for lead-free solder on a temperature-controlled iron. Kester's recommendations depend on the flux: about 400 °C for its rosin-flux wires and 315–345 °C for its no-clean wires. More in 63/37 vs 60/40 vs SAC305 solder

Is lead-free solder safer to use?

It removes lead exposure, not flux fumes. The same rosin-based flux cores are sold on lead-free wire, and HSE names rosin flux fume as a top cause of occupational asthma, so extraction still matters. More in 63/37 vs 60/40 vs SAC305 solder

Is it safe to touch leaded solder?

HSE lists breathing lead dust or fume and swallowing lead as the ways it is absorbed, so the risk from handling solder is lead reaching your mouth. Wash your hands and face and scrub your nails before eating, drinking or smoking. More in 63/37 vs 60/40 vs SAC305 solder

What is SAC305 solder?

A lead-free tin-silver-copper alloy, Sn96.5Ag3Cu0.5. Kester lists its melting range as 217–220 °C and notes that the Solder Products Value Council standardized on this composition. More in 63/37 vs 60/40 vs SAC305 solder

What solder should a beginner buy for electronics?

A flux-cored wire with a stated alloy and flux type, about 0.5–0.8 mm thick by our rule of thumb. Leaded 63/37 melts at 183 °C and is easier to work; lead-free SAC305 melts at 217–220 °C and suits homes where you want no lead. More in How to choose solder for electronics

Can I use acid-core solder on a circuit board?

No. Canfield, a solder maker, says acid-core solder is not recommended for electrical or electronic work because its residue is corrosive. More in How to choose solder for electronics

Is lead-free solder harder to use?

Yes. iFixit describes lead-free tin-silver-copper solder as harder to work with because of poorer wetting, and Adafruit says it may need more heat and more flux than leaded solder. More in How to choose solder for electronics

Do I need separate flux if my solder has a flux core?

For simple joints, the core may be all you need. For rework, desoldering and heavy joints, extra flux helps: SparkFun's fix for ground planes and large through-holes includes adding flux. More in How to choose solder for electronics

What does ROL0 mean on a solder data sheet?

It is a J-STD-004 flux code: RO for rosin, L for low activity and 0 for no detectable halides. Kester's 275 no-clean wire is one example rated ROL0. More in How to choose solder for electronics

Do I need to clean no-clean flux off the board?

No. SparkFun says cleaning and flux removal are not required with no-clean flux. Clean it with isopropyl alcohol only if you want the board to look clean or need to inspect the joints. More in How to clean flux residue

What is the best solvent for flux residue?

For no-clean residue, SparkFun suggests isopropyl alcohol. For other fluxes, use the cleaner named on the flux maker's data sheet, and for water-soluble flux follow the maker's washing process. More in How to clean flux residue

Why must water-soluble flux residue be removed?

Water-soluble flux is designed to be washed off after soldering, and SparkFun says to remove any residue that remains. If you cannot clean a board thoroughly, use a no-clean flux instead. More in How to clean flux residue

Is rosin flux residue harmful to the board?

Normally not. Kester says rosin residue is non-conductive and non-corrosive and removing it is cosmetic. The exception is a board that runs above 200 °F (about 93 °C), where the residue melts, becomes conductive and must be removed. More in How to clean flux residue

How long should a board dry after cleaning with alcohol?

Until no liquid remains anywhere, including under chips and inside connectors. Alcohol is flammable and a wet board can short, so check before you apply power rather than going by the clock. More in How to clean flux residue

Is no-clean flux the same as rosin flux?

Not by definition, though the two can overlap. Rosin describes what the flux is made of, while no-clean describes the residue. Kester's 275 no-clean wire, for example, carries the rosin code ROL0. More in Rosin vs no-clean vs water-soluble flux

Do I have to clean no-clean flux off the board?

No. SparkFun says cleaning and flux removal are not required with no-clean flux. Use isopropyl alcohol if you want to remove the residue for looks or inspection. More in Rosin vs no-clean vs water-soluble flux

Can I leave rosin flux residue on a board?

Usually. Kester says rosin residue is non-conductive and non-corrosive and removal is cosmetic, unless the board runs above 200 °F (about 93 °C), where the residue melts, becomes conductive and must be removed. More in Rosin vs no-clean vs water-soluble flux

What does RMA flux mean?

Mildly activated rosin, an older label. Kester's 185 liquid flux is sold as RMA and classified ROL0 under J-STD-004, but that applies to that product; an unbranded RMA syringe may not match it. More in Rosin vs no-clean vs water-soluble flux

Can I use plumbing or acid flux on electronics?

No. Canfield, a solder maker, says acid-core solder is not recommended for electrical or electronic work because its residue is corrosive. Buy flux labeled for electronics. More in Rosin vs no-clean vs water-soluble flux

Soldering stations and irons

Is a higher-wattage soldering station always better?

No. Power ratings follow the job: JBC rates its precision T210 handle at 40 W peak and its general-purpose T245 handle at 150 W peak. Choose the tip system for the work you do, then a station that runs it. More in Soldering stations and irons: how to choose

Can I use a 220 V soldering station in the US?

Choose the 110-120 V variant instead. US household power is 110-120 V at 60 Hz, and makers such as Weller sell separate 120 V and 230 V versions of the same station. Do not rely on a plug adapter. More in Soldering stations and irons: how to choose

Is the Hakko FX-888D still made?

Hakko's global site marks the FX-888D as discontinued. Its successor, the FX-888DX, still takes T18 tips on its FX-8801 iron and is rated 100 W at 120 VAC by American Hakko. More in Soldering stations and irons: how to choose

How long does a soldering station take to heat up?

It depends on the design. Weller quotes about 28 seconds from 50 to 350°C for its WE1010NA station, and Tom's Hardware timed a Pinecil V2 at 10 seconds to working temperature (one unit, its own method). More in Soldering stations and irons: how to choose

Are the Pinecils sold on AliExpress genuine?

Pine64 says no: it states that no Pine64 Pinecils are sold on AliExpress and that it has no authorized resellers there. Genuine units bought after August 2, 2022 should pass Pine64's online authenticity checker. More in Soldering stations and irons: how to choose

Is the KSGER Official Store on AliExpress run by KSGER?

We could not confirm it. A store with that name exists, and an EEVblog forum post links to it, but we found no KSGER-controlled website that confirms who runs it. We call it a store named KSGER Official Store, not a brand-official store. More in KSGER T12 V3.1S vs YIHUA 982-III

Does the YIHUA 982-III work on 120 V?

The YIHUA-branded spec page rates it for 110-240 V, and the seller describes both of its variants as 120 V with a US plug. Choose one of those variants; the spec page's ownership is not independently confirmed, so check the rating on the unit when it arrives. More in KSGER T12 V3.1S vs YIHUA 982-III

Does the YIHUA 982-III take C245 tips?

The seller sells a 'C245 set' variant, but the YIHUA-branded spec page we found lists only C115 and C210 handle packages. Treat C245 as the seller's description and check the handle shown on the listing before you order tips. More in KSGER T12 V3.1S vs YIHUA 982-III

Are the KSGER station's T12 tips made by Hakko?

Treat them as T12-format tips, not Hakko parts. Hakko sells its genuine cartridges in North America under T15 part numbers and warns that counterfeits can carry its logo. More in KSGER T12 V3.1S vs YIHUA 982-III

Which station is better for ground planes and big connectors?

Neither listing publishes enough to say. JBC designs its own C245 system for high-power work such as ground planes, but its ratings do not transfer to compatible handles. For any station, SparkFun suggests a larger tip, more heat and extra flux on ground planes. More in KSGER T12 V3.1S vs YIHUA 982-III

Can I buy a genuine Pinecil on AliExpress?

No. Pine64 states that there are no Pine64 Pinecils sold on AliExpress, that the ones there are not made by Pine64, and that it has no authorized resellers on AliExpress, whatever a store calls itself. More in Pinecil vs TS101

Do the Pinecil and TS101 use the same tips?

Both are documented with TS100-style tips: Pine64 for the Pinecil V2, and Oscar Liang's review for the TS101. Pine64 does not mention TS101-branded tips, so do not assume those fit a Pinecil. More in Pinecil vs TS101

What charger do I need for a Pinecil V2?

A USB-C PD charger. Pine64 recommends at least 65 W (3.25 A at 20 V), or a higher-voltage supply, when using its short tips. You do not need a 100 W charger. More in Pinecil vs TS101

How can I tell if my Pinecil is genuine?

A genuine new Pinecil V2 comes in a white box, with a black handle and a green silicone thumb grip, and units bought after August 2, 2022 should pass Pine64's online authenticity checker. More in Pinecil vs TS101

Is the TS101 as powerful as the Pinecil on USB-C?

On paper it is lower. Its USB-C input is rated up to 45 W, and its 65 W rating needs a DC supply. The Pinecil V2 takes USB-C PD up to 20 V; at 20 V Pine64 calculates 50 W with an 8-ohm tip and 64.5 W with a short tip. More in Pinecil vs TS101

What is the difference between Pinecil V1 and V2?

Pine64 rates the V2 up to 88 W at 24 V, against 65 W for the V1, and only the V2 accepts Pine64's short tips; the V1 takes normal-length TS100-style tips only. More in Pinecil vs TS101

Why won't solder melt on a ground pad when it melts fine elsewhere?

The copper plane draws heat away from the pad as fast as the tip supplies it, so the joint never reaches the solder's melting point. SparkFun's fix is a larger tip, a higher setting, extra flux and a little more time on the joint. More in Why ground planes are hard to solder

Should I just turn my iron up to the maximum?

No. SparkFun suggests 720 °F (about 380 °C) for heavy joints, and Kester's highest hand-soldering recommendation is about 400 °C. Past that, a bigger tip, more flux, a more powerful handle or a preheater will do more than extra degrees. More in Why ground planes are hard to solder

Which tip system is best for ground planes?

A high-power one. JBC rates its T245 handle for C245 cartridges at 150 W peak and says it suits high-power work such as ground-plane soldering. See C210 vs C245. More in Why ground planes are hard to solder

Is a USB-C soldering iron enough for ground planes?

It has less in reserve than a large station handle. By Pine64's arithmetic, a Pinecil with an 8-ohm tip draws 50 W at 20 V, and its official maximum is 88 W at 24 V, against 150 W peak for JBC's T245 handle. More in Why ground planes are hard to solder

Do I need a preheater to solder ground planes?

Not for occasional joints, but it helps on multi-layer boards. Hakko markets its FR-830 hot-air preheater as best suited to preheating multi-layer boards. See do you need a PCB preheater? More in Why ground planes are hard to solder

Tips and cartridges

Do T12 tips fit a C245 handle?

Neither maker lists them as interchangeable. Hakko lists T12 and T15 cartridges for its FM-2027 and FM-2028 irons, and JBC lists C245 cartridges for its T245 handle. Buy tips listed for the handle you have. More in Soldering tips and cartridges

What is the difference between T12 and T15 tips?

Mainly the region: Hakko sells T12 tips in Japan, Oceania, Asia and other countries, and T15 tips in North America and Europe. Treat marketplace 'T12' tips as T12-format parts unless the seller can show Hakko authorization. More in T12 vs T15 tips. More in Soldering tips and cartridges

Which soldering tip shape should a beginner buy?

Start with a chisel tip for through-hole work and add a fine point for very small surface-mount parts, as Adafruit's Collin's Lab suggests. More in Soldering tips and cartridges

Can I sand or file a dirty soldering tip?

No. Adafruit warns that files and abrasives damage a tip's plating and ruin it. A badly oxidized tip can usually be reconditioned with tip-tinning paste. More in Soldering tips and cartridges

Does the Pinecil take TS100 tips?

Yes. Pine64 says the Pinecil V2 accepts its own short tips and normal-length TS100-style tips and detects the tip at boot; the V1 takes normal-length TS100-style tips only. More in Soldering tips and cartridges

Are JBC tips sold on AliExpress genuine?

We could not establish that either way. We found no JBC statement about marketplace sellers, so we describe such cartridges as C245- or C210-compatible and never as genuine JBC parts. More in Soldering tips and cartridges

Is C115 better than C210 for phone repair?

Only for the very smallest parts. JBC rates its C115 nano station at 25 W peak for high-precision micro-soldering, while the C210's T210 handle is rated 40 W peak and also handles conventional components. For mixed phone-board work, we suggest starting with C210. More in C115 vs C210

What happened to JBC C105 cartridges?

JBC says its C105 range will be discontinued and replaced by C115, which works with the NT115 nano iron and the AN115 and NP115 nano tweezers. More in C115 vs C210

Do C115 cartridges fit hot tweezers?

In JBC's system, yes: JBC lists C115 cartridges for its AN115 and NP115 nano tweezers as well as the NT115 nano iron. Compatible tweezers from other makers are their own designs, so check their specifications. More in C115 vs C210

Do I need a microscope to use C115 tips?

In practice, yes. JBC describes its CDN nano station as made for high-precision micro-soldering and microscope work. Choose a microscope with enough working distance for the tool; see digital vs stereo microscope. More in C115 vs C210

Which package sizes need C115 rather than C210?

JBC does not say. It describes C115 by purpose, very small components at high precision, rather than by package size. If a fine C210 tip reaches every pad you work on, you do not need C115 yet. More in C115 vs C210

Can I put a C210 cartridge in a T245 handle?

Do not plan on it. JBC lists C210 cartridges for its T210, B.100 and B.500 handles, and C245, C245E and C245L cartridges for the T245. Buy the handle that matches the cartridge family you want. More in C210 vs C245

Is C245 better than C210?

Neither is better; they do different jobs. JBC rates the T245 handle at 150 W peak for SMD and high-power work such as ground planes, and the T210 at 40 W peak for accurate, medium-power work, including under magnification. More in C210 vs C245

Do I need C210 for phone repair?

It helps with the fine joints: JBC positions C210 for small SMD work, even under a microscope. Connectors and shields still suit C245, and the very smallest parts suit C115. See C115 vs C210. More in C210 vs C245

Are C245 tips on AliExpress genuine JBC?

We cannot confirm it either way. We found no JBC statement on which marketplace sellers are authorized, so we describe third-party tips as C245-compatible. JBC's power and tip-life figures do not apply to them. More in C210 vs C245

What is the difference between T245 and C245?

T245 is JBC's general-purpose handle; C245 is the cartridge family it takes. The T245 also accepts C245E and the longer C245L cartridges. More in C210 vs C245

What soldering tip shape should a beginner buy?

A small chisel. Adafruit recommends a flat, screwdriver-style tip for through-hole parts, and a flat face puts more metal on the joint than a point. Add a fine conical tip later if you work on very small surface-mount parts. More in Soldering tip shapes

Is a conical tip good for general soldering?

Not as your only tip. Adafruit suggests a fine point for very small surface-mount parts, but its small contact area makes larger joints slow to heat. SparkFun's first fix for heavy joints is a larger tip. More in Soldering tip shapes

What does the letter in a soldering tip part number mean?

It names a shape family within one maker's range, such as the B, C, D, I, J and K groups in Hakko's T18 tips. Each maker defines its own codes, so check the maker's drawing rather than relying on the letter. More in Soldering tip shapes

Can I file or sand a soldering tip into a different shape?

No. Adafruit warns that files and abrasives damage a tip's plating and ruin the tip. Buy the shape you need within your tip system instead. More in Soldering tip shapes

Which tip shape is best for drag soldering?

A shape with a flat or cupped face that holds a small pool of solder: a bevel, knife or spoon. Adafruit notes that a bridge can usually be drawn off by dragging a hot tip between the joints, which these shapes do well. More in Soldering tip shapes

Is a T12 tip the same as a T15 tip?

Hakko uses the two names as regional series for its FM-2027 and FM-2028 irons: T12 for Japan, Oceania, Asia and other countries, T15 for North America and Europe. We found no Hakko page comparing them part by part, so match part numbers to your iron. See T12 vs T15 tips. More in T12 vs C245 soldering tips

Are the T12 tips sold on AliExpress made by Hakko?

Treat them as T12-format tips from other makers unless the seller proves Hakko provenance. American Hakko tells buyers to use authorized distributors and warns that counterfeits can copy its designs and even carry its logo. More in T12 vs C245 soldering tips

Is C245 better than T12?

Not across the board. JBC rates its T245 handle at 150 W peak and aims it at both SMD and high-power work such as ground planes, while Hakko stresses its T12 cartridge's fast thermal recovery. Choose by the joints you solder and the handles you may add later. More in T12 vs C245 soldering tips

Can one station use both T12 and C245 tips?

Only a station built for both handle types. AiXun, for example, lists a T3A station for T245 and T12 handles. Otherwise, plan on one tip system per station. More in T12 vs C245 soldering tips

Do JBC's specifications apply to C245-compatible tips?

No. JBC's ratings, such as the T245 handle's 150 W peak, describe JBC's own handles and cartridges. Compatible tips and handles carry their own makers' claims, which we treat as unverified. More in T12 vs C245 soldering tips

Are T12 and T15 soldering tips the same?

Hakko presents them as regional series for the same FM-2027 and FM-2028 irons: T12 for Japan, Oceania, Asia and other countries, T15 for North America and Europe. We found no Hakko page comparing them part by part, so we do not claim they are interchangeable. More in T12 vs T15 tips

Will genuine Hakko T15 tips fit my AliExpress T12 station?

We cannot confirm it. Hakko lists its cartridges for its own irons, and a T12-format station's maker sets its own specification. Buy the cartridges your station's maker lists, or get the seller to confirm the fit in writing. More in T12 vs T15 tips

Are the T12 tips sold on AliExpress made by Hakko?

Treat them as T12-format tips from other makers unless the seller proves Hakko provenance. American Hakko tells buyers to use authorized distributors and warns that counterfeits can copy its designs and even carry its logo. More in T12 vs T15 tips

Is the Hakko FX-950 still made?

No. Hakko's FX-950 page marks it discontinued from April 2025 and names the FX-971 as its successor. More in T12 vs T15 tips

Does the Hakko FX-888DX use T12 or T15 tips?

Neither. American Hakko lists the FX-888DX's standard FX-8801 iron with T18 tips, a separate system, and the station is rated 100 W at 120 VAC. See the Hakko T18 tip system. More in T12 vs T15 tips

How powerful is a T12 soldering iron?

Hakko lists 70 W power consumption at 24 V for its own FM-2027/FM-2028 iron. T12-format clones publish their own figures, which Hakko's specification does not cover. More in T12 vs T15 tips

Should I sand or file a soldering tip that won't tin?

No. Adafruit warns that files and abrasives damage the plating and ruin the tip. Use tip-tinning paste instead, which Adafruit says can usually recondition a badly oxidized tip. More in Why solder won't stick to the tip

Why did my new soldering tip turn black so quickly?

A tip left hot without a coat of solder has nothing protecting it. Tin a new tip as soon as it first reaches temperature, re-tin before each joint as SparkFun recommends, and never park it freshly wiped and bare. More in Why solder won't stick to the tip

Will a higher temperature help solder stick to the tip?

Only if the setting is too low for your alloy. Adafruit suggests about 400 °C for lead-free and 370 °C for 60/40. Above your solder maker's recommendation, more heat does not fix an oxidized or worn tip. More in Why solder won't stick to the tip

How do I know a tip is beyond saving?

When the plating is pitted or worn through and no part of the working face will take solder, even after tip-tinning paste. On a cartridge system you then replace the whole cartridge, since Hakko builds the heater and sensor into its T12 tip. More in Why solder won't stick to the tip

Solder sticks to my tip but not to the pad. Is the tip the problem?

Probably not. SparkFun recommends heating the pad and the part together, and its fix for heavy joints is a larger tip, more flux and a little more time. See why ground planes are hard to solder. More in Why solder won't stick to the tip

How do I find out which tip system my station uses?

Read the model on the handle and the part number on a tip. JBC names its handles after the cartridge family (T245 for C245, T210 for C210), and Hakko lists T12 and T15 cartridges for its FM-2027 and FM-2028 irons. More in Soldering tip system finder

Do T18 tips fit every FX-888DX handpiece?

No. American Hakko lists T18 tips for the FX-8801 iron, T19 tips for the FX-8805 large iron and new T32 tips for the FX-8806. More in Soldering tip system finder

Do TS101 tips fit a TS80?

Not according to Oscar Liang's TS101 review, which says TS101 tips are compatible with the TS100 but not with the TS80 or TS80P. More in Soldering tip system finder

Why do some fields say 'Not confirmed'?

We show a value only when a manufacturer page or a named independent source states it. When none does, the field says so instead of repeating a listing claim as fact. More in Soldering tip system finder

Bench accessories

What do I need for my first soldering project?

A temperature-controlled iron, solder, flux and a way to remove solder. SparkFun's beginner lesson sets the iron to a medium heat of 325-375°C and has you tin the tip, and its accessories page recommends a solder vacuum for clearing through-holes. More in Repair bench planner

Do I need a microscope for phone repair?

For board-level phone work, plan on one. JBC describes its C210 cartridges as suitable for small SMDs even under a magnifying glass, and its smallest C115 cartridges for very small components, even under a microscope. See the phone microsoldering bench. More in Repair bench planner

Why drain the battery before a phone or laptop repair?

A charged lithium-ion battery may catch fire if it is damaged. iFixit's ROG Ally battery guide, for example, says to drain the battery below 25% before starting; follow your own device's guide. More in Repair bench planner

Were the kit picks tested?

No. We do not test products. Kit picks come from our catalog and listing research, and each one names the variant to choose and what remains unverified. More in Repair bench planner

Tip systems

Are T12 and T15 tips the same thing?

Hakko uses both names for one cartridge range: T12 for Japan, Asia, Oceania and other countries, and T15 for North America and Europe. Both fit Hakko's FM-2027 and FM-2028 irons. Third-party "T12" tips are T12-format cartridges from other makers, not Hakko parts. More in Hakko T12 / T15 and T12-format tips

Why do T12 tips recover heat so quickly?

Hakko builds the heating element and the temperature sensor into the tip itself. It says this gives superior thermal responsiveness and greatly improved thermal recovery, so you can often work at a lower set temperature. More in Hakko T12 / T15 and T12-format tips

Is a T12 station from another brand a Hakko product?

No. It takes T12-format tips, but it is not made by Hakko. American Hakko warns that counterfeits can copy Hakko's designs, colors and even its logo, and advises buying only from authorized Hakko dealers. More in Hakko T12 / T15 and T12-format tips

Can T12 tips go in a C245 handle?

No. T12 cartridges fit Hakko FM-2027/FM-2028-style handles and C245 cartridges fit JBC T245-style handles. Some third-party stations accept both handle types (AiXun lists a T245/T12 model), but each cartridge still needs its own handle. More in Hakko T12 / T15 and T12-format tips

Is C245 better than T12?

For heavy joints it has more headroom: JBC rates its T245 handle at 150 W peak and names ground planes as a C245 job, while Hakko rates its T12 iron at 70 W. The two figures are measured differently, and for general bench work either system does the job. More in C245 cartridges (JBC T245 handle)

Are AliExpress C245 tips genuine JBC?

We could not confirm either way. We found no JBC statement listing authorized marketplace sellers, so we describe third-party tips as C245-compatible and do not assume JBC's quality or tip life. More in C245 cartridges (JBC T245 handle)

Do C245 tips fit a C210 handle?

No. JBC makes C245 cartridges for the T245 handle and C210 cartridges for its T210, B.100 and B.500 precision handles. Stations that take both need both handles. More in C245 cartridges (JBC T245 handle)

What is C210 best for?

JBC says the T210 handle and C210 cartridges suit accurate soldering with medium power needs: small SMD parts, work under a magnifying glass and conventional components. Its CDS station page calls the system ideal for soldering SMD. More in C210 cartridges (JBC T210 handle)

Should my first precision station be C210 or C245?

If most of your work is small SMD parts under magnification, choose C210. If you also solder ground planes, thick wires or big connectors, choose C245, which JBC rates at 150 W peak against 40 W for the T210. Some stations take both handles, so you may not have to choose. More in C210 cartridges (JBC T210 handle)

Is C210 enough for phone board repair?

For many jobs, yes: JBC positions C210 for small SMD parts under magnification. For the very smallest components JBC makes the C115 nano range, used with its NT115 iron under a microscope. More in C210 cartridges (JBC T210 handle)

Do I need C115 for phone repair?

Usually not as a first system. JBC positions C210 (40 W peak) for small SMD parts under magnification and C115 (25 W peak) for the very smallest components under a microscope. Start with C210 and add C115 when parts get too small for it. More in C115 nano cartridges (JBC NT115)

What replaced JBC's C105 cartridges?

C115. JBC says its C105 range will be discontinued and replaced by C115, which works with the NT115 nano iron and the AN115 and NP115 nano tweezers. More in C115 nano cartridges (JBC NT115)

Will a C115 cartridge fit a C210 handle?

No. JBC lists C115 for its NT115 nano iron and nano tweezers, while C210 cartridges fit its T210, B.100 and B.500 handles. More in C115 nano cartridges (JBC NT115)

Does the Pinecil use TS100 tips?

Yes. Pine64 says the Pinecil V2 takes normal-length TS100-style tips as well as Pine64's own short tips, while the V1 takes normal-length TS100-style tips only. More in TS100-style tips (TS100, TS101, Pinecil)

What charger does a TS100-style iron need?

One that supplies the voltage your iron and tip need. Pine64 shows an 8-ohm tip giving 50 W at 20 V and 72 W at 24 V, and recommends at least a 65 W USB-C PD charger (3.25 A at 20 V) for its short tips. A much bigger charger is not required. More in TS100-style tips (TS100, TS101, Pinecil)

Are Pinecils sold on AliExpress genuine?

Pine64 says no: no genuine Pinecils are sold on AliExpress and it has no authorized resellers there. Genuine V2 units bought after August 2, 2022 should pass Pine64's online authenticity checker. More in TS100-style tips (TS100, TS101, Pinecil)

Which heats up faster, the Pinecil V2 or the TS101?

In Tom's Hardware's single-unit timing, the Pinecil V2 reached working temperature in 10 seconds, and its TS101 review reports 15 seconds. Oscar Liang timed his TS101 at 15 seconds on USB-C PD and 10 seconds on 24 V DC, so the power source matters. More in TS100-style tips (TS100, TS101, Pinecil)

Is the Hakko FX-888D still made?

No. Hakko's global site marks the FX-888D discontinued. The current FX-888DX still uses T18 tips on its standard FX-8801 iron. More in Hakko T18 tips (FX-888D and FX-888DX)

Do T18 tips fit the FX-888DX?

Yes, on its standard FX-8801 iron; American Hakko lists the T18-D16 as the US standard tip. The optional FX-8805 large iron takes T19 tips and the FX-8806 high-power iron takes T32 tips. More in Hakko T18 tips (FX-888D and FX-888DX)

How can I tell a genuine Hakko station?

American Hakko advises buying only from authorized Hakko distributors and dealers. It warns that counterfeits can copy Hakko's designs, colors and logo, and says most authentic sellers are based in the US and Canada with 120 V products. More in Hakko T18 tips (FX-888D and FX-888DX)

Project benches

What tip should I use for keyboard switches?

A medium chisel tip. Switch pins are through-hole joints, and Adafruit says a flat chisel (screwdriver) tip works well for through-hole parts; a fine conical point heats them slowly. More in Mechanical keyboard switches

Leaded or lead-free solder for a keyboard?

Either works. Kester lists 63/37 leaded solder at 183°C and lead-free SAC305 at 217-220°C, so lead-free needs more heat. If you use leaded solder, wash your hands before eating or drinking (HSE). More in Mechanical keyboard switches

Do I need a soldering station for a keyboard?

You need temperature control, whatever the form. A station or smart iron lets you hold a steady temperature in SparkFun's 325-375°C learning range; a basic plug-in iron without control gives you no way to set it. More in Mechanical keyboard switches

Can I build an FPV drone with a USB-C soldering iron?

Yes for most joints, with a strong enough supply. Pine64 rates the Pinecil V2 at up to 88 W at 24 V through its DC input (its USB-C PD input runs at 12-20 V) and lists LiPo packs among its power options. Thick battery leads and connectors are easier on a bench station; JBC rates its T245 handle at 150 W peak. More in FPV drone builds and repairs

Can I power a soldering iron from a flight pack?

Some irons support it. Pine64 lists 3S, 4S and 5S LiPo packs for the Pinecil V2 and Sequre lists 3S-6S for its SI012, while Oscar Liang notes that a full 6S pack is not officially supported on the TS101. Check your iron's maximum input voltage first. More in FPV drone builds and repairs

What should I do with a damaged LiPo pack?

iFixit warns that a charged lithium-ion battery may catch fire if damaged. EPA says to keep lithium batteries out of household trash and recycling bins, tape the terminals or bag them separately, take them to battery recycling or household hazardous waste collection, and contact the maker about damaged ones.

Pump or wick for removing old capacitors?

Usually both. SparkFun calls a solder vacuum a great tool for clearing solder left in through-holes, and wick, braided copper that soaks up solder, cleans what remains off the pads. More in Retro console recap

Do I need a desoldering gun for one recap?

Not for one console. A desoldering gun such as Hakko's FR-301 heats the joint through its nozzle and vacuums the solder away in one step, which pays off when you clear many holes. More in Retro console recap

What temperature should I use on old leaded joints?

Adafruit suggests about 370°C (700°F) for 60/40 leaded solder on a temperature-controlled iron, and SparkFun teaches 325-375°C as a starting range. Big ground joints may need more heat and a larger tip. More in Retro console recap

Do I need C115 to start phone repair?

Usually not. JBC positions C210 (40 W peak) for small SMD parts under magnification and C115 (25 W peak) for the very smallest components under a microscope, so C210 covers more first jobs; add C115 when parts get too small for it. More in Phone microsoldering

Digital or stereo microscope for phone boards?

A stereo microscope gives each eye its own view, so you can judge depth when placing the iron; AmScope advertises an 8-inch (200 mm) working distance for its SM-6TZ, depending on the Barlow lens fitted. Digital screen microscopes make recording easy, but some EEVblog users find lag and the flat image harder to work under. More in Phone microsoldering

Why use a bench power supply on a phone board?

It powers the board from a set voltage with a current limit you choose, and shows how much current the board draws. If a short tries to pull more, the supply holds the current at the limit instead (Tektronix), which helps you find the fault without overheating the board. More in Phone microsoldering

Do I need an oscilloscope for laptop repair?

Not to start. A multimeter and a bench supply cover first checks; a scope helps when the fault involves timing, such as clocks or switching regulators. Tektronix's rule of thumb is a bandwidth at least five times the highest frequency component you need to measure. More in Laptop board repair

C245 or C210 for laptop boards?

Both, ideally. JBC designs C245 for SMD work and high-power jobs such as ground planes, and C210 for precision work with medium power. Several third-party stations take both handle types; AiXun lists some. More in Laptop board repair

Do I need a preheater for laptop boards?

It helps on thick multilayer boards but is not a first purchase. A preheater warms the whole board so the iron or hot air has less heat to supply; Hakko markets its FR-830 as best suited to multi-layer boards. More in Laptop board repair

Can I replace a USB-C port with only a soldering iron?

Sometimes, on connectors with through-hole tabs and few pads, but hot air makes the job much easier because it melts every joint at once. Plan on hot air plus an iron for the tabs and cleanup. More in USB-C port repair

Do I need C115 for a USB-C port?

Usually not. JBC positions C210 for small SMD parts under magnification, which suits connector pins; C115 is JBC's range for the very smallest components. More in USB-C port repair

What should I do about the battery before a port repair?

Follow your device's repair guide. iFixit warns that a charged lithium-ion battery may catch fire if damaged, and its ROG Ally battery guide, for example, says to drain the battery below 25% before starting. More in USB-C port repair

Hot air or soldering iron for an HDMI port?

Both. Hot air melts the pins and shield tabs together so the connector lifts cleanly; an iron with a broad tip and flux finishes the tabs and cleans the pads. More in HDMI port repair

Which tip system suits HDMI port work?

C245, with a C210 handle for fine touch-ups. JBC designs C245 for SMD work and high-power jobs such as ground planes, which matches the connector's ground tabs. More in HDMI port repair

Do I need a preheater for console boards?

It is an upgrade, not a first purchase. A preheater warms the whole board so the iron and hot air have less heat to supply, and Hakko markets its FR-830 hot-air preheater as best suited to multi-layer boards. More in HDMI port repair

When is a desoldering gun worth buying?

When you clear many holes. A gun such as Hakko's FR-301 heats the joint through its nozzle and vacuums the solder away in one step; a hand pump and wick do the same job more slowly. More in Through-hole restoration

Why won't the solder come out of a hole?

Usually not enough heat reaches the joint. SparkFun's advice for ground planes and large through-holes is a larger tip, a higher temperature, extra flux and a little longer on the joint. More in Through-hole restoration

Is it safe to work on old mains-powered equipment?

Only on the low-voltage parts unless you are trained. Unplug it, and leave the mains wiring and high-voltage sections to a qualified technician; OSHA's workplace rules require stored energy in capacitors to be released before anyone works on deenergized equipment. More in Through-hole restoration

Do I need hot air for SMD prototypes?

Not at first. An iron with flux handles most leaded and two-terminal parts; hot air or a hot plate earns its place when you use solder paste or parts with pads underneath. More in SMD prototyping

What solder diameter suits SMD work?

Thin wire, around 0.3-0.5 mm, makes it easier to feed small amounts. Kester sells its 275 no-clean cored wire in diameters from 0.25 mm up. More in SMD prototyping

Which flux should I use for hand-soldered SMD boards?

A no-clean flux is the easiest start: SparkFun says its residue does not need cleaning, while water-soluble flux residue must be removed from the board. More in SMD prototyping

What temperature should I set for kit soldering?

SparkFun teaches 325-375°C as a starting range. Adafruit suggests about 370°C (700°F) for 60/40 leaded solder and 400°C (750°F) for lead-free on a temperature-controlled iron. More in Arduino and starter kits

Leaded or lead-free solder for a beginner?

Leaded 63/37 melts at 183°C and wets well, which makes it forgiving (iFixit); lead-free SAC305 melts at 217-220°C and needs more heat. With leaded solder, wash your hands before eating or drinking (HSE). More in Arduino and starter kits

Do I need a fume extractor for a few kits?

At least ventilate and keep your face out of the smoke. HSE says rosin-based solder flux fume is a top cause of occupational asthma; if you solder regularly indoors, add extraction at the source. More in Arduino and starter kits
