Best Soldering Iron For Circuit Boards
Can you damage a circuit board with a soldering iron?
If you use too powerful of a soldering iron on a circuit board you might damage the components you are trying to join. I like to keep a low-wattage iron around for detail work, and a high-wattage iron that I can use when I am not too concerned about exposing the material I am working with to high temperatures.
What type of soldering iron should I use for electronics?
For basic non-temperature controlled irons, a wattage of 40 watts may be good for general work, and higher if heavy soldering is envisaged. For small PCB work, 15 or 25 watts is a good value.
What is the best tip for soldering circuit boards?
Chisel tips are the most popular tip shape, and they are useful for a wide range of soldering tasks. The wide edge of chisel tips helps them to spread heat uniformly through part leads and pads. The chisel tip is an excellent choice for a variety of applications.
What soldering iron Do professionals use?
Best Professional Soldering Iron—Hakko Soldering Iron With a 97% positive rating, this top tool from Hakko that knows its stuff is lightweight, ergonomic, has variable temperature control and features a ceramic heater and advanced electronic controls.
Why is my solder not stick to circuit board?
This issue is usually caused by the soldering iron being set to an improper temperature, or the iron itself has a wattage that is too low for the solder size you are using. If you notice your solder isn't sticking, check your solder material and compare it to the wattage of your soldering iron.
What kind of solder to use on circuit boards?
Lead solders were, for a long time, the go-to substance in the electronics industry. They have a melting point of around 180-190°C. The most commonly existing blend is the 60/40 (tin/lead) blend. Tin helps maintain a lower melting point.
What type of solder should not be used for electronics?
The main types of solder are lead and lead-free. You can use both for electronics, but it can be easier to work with lead-based solder. Make sure to stay away from acid core solder as this is intended for plumbing, NOT electronics.
What temperature should I solder my circuit board?
600°- 650°F (316°- 343°C) is a good place to start for lead-based solder and 650°- 700°F (343°- 371°C) for lead-free solder. Hold the tip against both the lead and contact point/pad for a few seconds. The idea is to bring both up to a soldering temperature at the same time.
Is a 25w soldering iron good for electronics?
Once you have a good temperature control, then something in the 20 to 50 watt range is good. If for some reason you can't get good temp control then stick with an iron that is less than 25 watts.
What watt soldering iron do I need for electronics?
For electronics work, 16 watts is considered low, 50 watts is mid range, and 130 watts is high. Essentially you need an iron that maintains an even heat loss to generation ratio. This is especially important if your iron doesn't have temperature control.
What size solder is best for electronics?
For most electronics work, solder in the range of 0.4 - 1.0 mm in diameter will work well. If you perform a lot of work on surface mounted devices, aim for the lower end of this range. ... There are three commonly used lead-based alloys for electronic soldering:
- 60/40 (Sn/Pb).
- 63/37 (Sn/Pb). ...
- 62/36/2 (Sn/Pb/Ag).
Should you leave solder on the tip?
Soldering tips oxidize as exposed to the air. Make sure to leave some solder on the tip to cover the pre-tinned area when placing the iron in the holder. If there is not enough solder left on the tip after soldering, clean the tip and apply some solder to cover its pre-tinned area. It helps prevent tip oxidation.
What are 3 typical soldering mistakes?
5 Common Solder Mistakes and How to Resolve Them
- Disturbed Joint. A disturbed joint typically occurs as a result of movement while the alloy is solidifying.
- Solder-Starved Joint. A solder-starved joint is just that: a joint that does not have enough solder. ...
- Untrimmed Leads. ...
- Cold Solder Joint. ...
- Solder Bridge.
Is it better to crimp or solder?
Crimping offers stronger, more reliable connections than soldering. Soldering uses heated metal to join the cable to the connector. Over time, this filler metal will degrade, which may cause the connection to fail. Most electricians will agree that crimping is also easier than soldering.
Is it worth buying expensive soldering iron?
Functionally, there is very little difference between a $15 and $80 soldering iron; they work well enough for small jobs (buy a nice iron if you plan on doing a lot of soldering work). An inexpensive fine-tip soldering iron can do fine-pitch work; the tip is generally the limiting factor (cheap tips wear quickly).
Is a higher watt soldering iron better?
Higher wattage soldering iron have more power, thus making them better suited for heavy-duty projects than their low-wattage counterparts. Higher wattage doesn't mean that the iron provides more heat; rather, high-wattage soldering irons have more power on reserve, enabling them to heat for longer periods.
What is the best solder for electrical work?

Why does my solder just ball up?
Solder balls are caused by gassing and spitting of the flux on the surface of the wave or by solder literally bouncing back from the solder wave. This is caused by excessive back flow in air or too high a drop in nitrogen environments.
Does flux help solder stick?
With compatible metals, however, you must use a suitable flux after preparing the metal surface to remove any oxidation. The flux will prevent new oxidation from forming when you heat the metal. If you have a compatible and corrosion-free surface, then the solder will stick.
