What Is Soldering Wick ?

Soldering wick is one of the easiest desoldering techniques.

The best thing about it is that – you do not need any specialized equipment to perform desoldering using the soldering wick method. Whether you are an experienced person or a beginner, the soldering wick technique will serve you the purpose of desoldering.

Soldering wick, also known as desoldering braid, is a type of desoldering method to remove solder and disassemble electrical components.

The following article goes into detail about soldering wick and how to perform desoldering using it. Besides, the article also highlights the pros and cons of soldering wick.

What is Soldering Wick?


Soldering wick comes in a coil with strands of copper wire braided together. And, hence the name, desoldering braid. Since copper is a good conductor of heat and solder is attracted to heat, heating up the copper braid sucks the solder from the metal. Some desoldering braids come with flux to make the process of removing flux easier.

If your desoldering braid does not have flux, you can apply the flux separately by dipping the tip of the braid into the flux.

How To Use Soldering Wick?

Soldering wick comes in very handy when you need to remove excess solder from a PCB. Especially if you are a beginner, having a soldering wick will help you correct your mistakes quickly.

Before starting the desoldering process, you have to prepare yourself in the same manner when you solder metals. Wear protective gear, use an exhaust fan, and have a first aid kit ready.

After that, follow the steps listed below to remove excess solder from the metal work piece.

  • Unwind a few inches of the braid.
  • If your desoldering braid does not contain flux, you can add flux by dipping the end into the flux.
  • Keep the braid over the joint.
  • Hold a hot soldering iron against the braid for some time.
  • You will notice the solder flows off from the joint and onto the braid.
  • Detach the braid from the joint. Do not touch the braid with your hands as it will be very hot.
  • Repeat the same step for 4 to 5 times until you remove all the excess solder.
  • Remove the component.

Benefits of Soldering Wick

Below are the benefits of using soldering wick to remove solder from the metal surface,

  • The process is very affordable
  • It is simple and easy to use
  • Soldering wick is available in different sizes depending on the amount of solder you want to remove
  • It is ideal for removing solder from flat surfaces and SMD components
  • You can reuse the components

Disadvantages of Soldering Wick

Below are the disadvantages of using soldering wick,

  • You cannot reuse the desolder braid. You have to remove the used braid and start with a clean segment.
  • It is difficult to hold the braid as it gets very hot.
  • It is difficult to remove solder out of pin holes.

Frequently Asked Questions

What can be used as a solder wick?

You can make your solder wick from a piece of stranded copper wire. You have to strip the wire and intertwine it. After that, dip the wire into flux. Now, you can use this as a solder wick.

Are you supposed to cut off the solder wick before or after you use it?

Yes, you have to cut off the solder wick after using it. Once the soldering wick becomes fully saturated with solder, you have to cut that portion of the wire. Then, you can use the solder wick again.

Does solder wick expire?

Yes, as the solder wick is made of copper, it will expire. When copper is exposed to atmospheric air, it interacts with the oxygen and oxidizes. You can notice the dark color of copper if the solder wick has expired.

Do you need to clean flux?

Yes, it is very important to clean excess flux after the soldering process. Flux is a chemical agent that is highly reactive. If left on the metal, it will react with the metal surface and cause corrosion. On top of this, the flux will also reduce the strength of the joint.

Can you desolder without flux?

Yes, it is possible to desolder without applying flux. However, using flux makes it easy to desolder. The flux reacts with the solder joints and weakens them. This makes it easy for you to desolder and break the joint.


Soldering wick is one of the easiest methods to desolder a PCB and remove unwanted solder. The soldering wick consists of braids of intertwined copper wires.

When you place the soldering wick against the solder and heat it, the soldering wick absorbs the solder due to its high thermal conductivity. By this way, you can remove the solder from the PCB or any metal surface.
