How To Clean Soldering Flux
Flick away excess by flipping your wrist two or three times.
How to clean soldering flux. To clean water-soluble flux use Isopropyl alcohol. This is because corrosive flux continues to damage the board if not removed. While this may be adequate for no-clean flux where the goal is a visually clean PCB this may not be clean enough when more heavily activated fluxes are involved like RA or aqueous.
I am attaching photographs of the soldering marks for your reference. 1 Dip a clean toothbrush in isopropyl alcohol or acetone. If there is a significant amount of flux left on the piece or dirty solder consider using a soft brush to help with scrubbing.
Wipe of the excess flux from the soldered joint with a piece of paper towel. This depends greatly on what kind of solder and flux you used. After soldering we using Vapor Degreaser process with RHO-TRON 225 AES-L to clean up the flux.
The most common way to clean flux residues from a repair area is to saturate a cotton or foam swab with isopropyl alcohol or another cleaning solvent and rub it around the repair area. Solder flux residue can be removed in two steps. Isopropyl alcohol is generally used for the removal of flux residues on circuit boards.
Water-soluble Deionized water and simple detergents are enough to clean water-soluble solder fluxes. There are also several brands of chemical cleaners specifically designed to clean flux goop. But my motherboard now has yellow stains after marks of soldering or maybe soldering flux paste.
Take a clean brush. Hi migs i use a flux removing spray you should get that from most electronic suppliers i use maplin or rapid electronics here in the UK. If I just soldered the board I literally just have to dunk it in an ethanol bath gently swish the PCB around to agitate things a bit and tip it as I take it out.
