10 Best Desoldering Guns for Effective Solder Removal in 2022

Desoldering is the removal of solder from circuit boards for repair or replacement. The basic concept is simple: first, you need to heat up the solder, remove the wire or the component, and then you need to clean up the remained solder that stays attached to the circuit board.

It looks easy in theory, but it usually takes a lot of practice to be good at desoldering. The best tip you can get is to make sure to remove all the solder from a hole at once. You can desolder with several different tools.

The best desoldering tools are desoldering pump (also called a solder sucker), desoldering bulb, electric vacuum desoldering pump (in the form of a pencil or a gun). Although not a tool, desoldering wire (also called a solder wick) and special alloys are also used for desoldering.

In this article, we will deal with electric desoldering guns and present you 10 best desoldering guns on the market.

How to Use Desoldering Pump?

Desoldering electric pump (or simply desoldering gun) has a nozzle that heats up the solder. When you press the trigger, it activates the vacuum pump that sucks the molten solder.

  • Plug in the desoldering gun and let it heat by setting the desired temperature.
  • Clean the area with isopropyl alcohol.
  • Place the nozzle over the solder joint, hold it in place. Make sure the nozzle is in complete contact with the solder joint. Wait until the solder melts completely.
  • The best way to check whether the solder is molten is to move the pin or wire with the gun’s nozzle from side to side. If it moves, the solder is ready to be sucked.
  • When the solder is molten, pull the trigger; it will activate the vacuum pump, and it will suck the solder up.

Desoldering guns are the most useful for desoldering a large number of through-hole components. They should not be used for tiny pieces due to the risk of sucking them up.

How to Desolder Without Pump?

It is possible to desolder without the solder pump. There are few items you can use to make it easier.

  • One is the abovementioned solder wick. Also known as desoldering wire, or desoldering braid) is a finely braided copper wire usually coated with rosin flux. It is easy to remove the solder from any flat surface; however, it is not recommended to remove the solder from pinholes. You need to cut a few inches from the spool, put it over the joint, and place a hot iron over the wire. After a few moments, the braid will suck up the solder by capillary action. At this point, the braid can be extremely hot, so be careful when removing it. Use needle-nose pliers to minimize the risk of getting burnt.
  • Another way is using ChipQuik alloy. It is a removal alloy with a low melting point of 136°F. Mixing the alloy with the solder already present on the joints creates a mixture with a low melting point. Using this alloy, you can move large surface mount components that otherwise would need a lot of continuous heat to molten. The best way to use it is to apply the ChipQuik alloy to the joint, use a soldering iron to heat it, and then remove the component with a pair of tweezers or even a toothpick. After the desoldering job, make sure to thoroughly clean the solder pads and surrounding area with isopropyl alcohol.
  • If you are so desperate or lack an appropriate desoldering tool, you can desolder only with a soldering iron. Heat it, melt the solder joints, tap the board’s side on a surface so that the solder falls off. Then remove the components by using pliers to pull them out. This option is risky because heat can damage the components or the board, especially if you reuse the parts.

Helpful Tips on Desoldering

  • Choose the appropriate desoldering tool for your situation.
  • Keep the tip of the tool and its spring clean to make it more durable.
  • If the board’s hole is still clogged after the desoldering, just add some more solder on it and start over.
  • It is easier to desolder if you first snip the component off because it can conduct heat and basically waste the heat you are applying to it.
  • You can always apply some additional flux to the old solder to encourage the solder to keep flowing off the board.
  • Be careful because flux fumes are highly toxic; keep your workspace
  • If desoldering a large continuous area of solder, you can heat it with the soldering iron at the same time to make sure all area melts before sucking it.
  • Minimize the area gun’s tip presses against the board as much as possible; too much heat can damage
  • Choose the right temperature for different situations/working areas – some boards require low temperature, while others are more heat resistant.
