How To Remove Solder Flux From Circuit Board

By | April 23, 2023



When it comes to repairing and maintaining circuit boards, one of the most important steps is removing solder flux. Solder flux is an essential part of any circuit board repair job, as it helps reduce oxidation and ensure a strong bond between components. Unfortunately, it can also leave a nasty residue on the board if not removed correctly. If you're unfamiliar with the process of removing solder flux from a circuit board, don't worry – it’s actually quite simple.

The first step is to use a flux remover. These are available in both liquid and paste forms, and work by effectively “eating” away the flux residue. Start by applying a generous amount of flux remover directly to the affected area, then let it sit for a few minutes. Once the flux has been dissolved, you can wipe it off with a clean, lint-free cloth.

Another option is to use a brush or scrubbing pad to remove the flux. This is a bit more labor-intensive than using a flux remover, but it can be effective in some cases. When using a brush or scrubbing pad, make sure to use gentle pressure and make sure to avoid scratching the board.

Removing solder flux from a circuit board may seem a bit intimidating, but with the proper tools and techniques, it doesn’t have to be. The key is to be patient and take your time. Once the flux has been removed, your circuit board will be ready to go and you can move onto the next stage of the repair job.
