Tools For Cleaning PCB after Soldering

Electronics Forum | Thu Mar 16 01:43:15 EDT 2017 | soldertraining

Hi! I have a very basic question about PCB cleaning. Which is the best way to clean the PCB after soldering? We use a lead free solder wire (3,5% flux inside the core) and after the soldering its a visible wetting,flux around the joint. When using th

Steve, I agree with the recommendation to check the temperature. This is the first place to go. Is this an IPA or water based Noclean? What is the topside temp of the assembly at the effected areas? If you are too cold you will have a tendency to hav

Tim, try and incorporate an inline wash system. We use one with a surfactant and it cleans the "NO CLEAN" fluxes well. If you dont have an inline system, you can manual clean the boards with an surfactant and IPA. You can also do an ionic contamin

Vinesh: You�ll find no papers that "clearly describes the harmful effects" of your style "of white residues," because no one is crazy enough to brag that they are doing what your customer wants you to do. The residue of no-clean fluxes are designe

White residue after cleaning with IPA

White residues are a common problem when cleaning no-clean fluxe residues. The white residue forms when the flux residue is partialy removed, etc. Alcohol should not be your only solution for cleaning. In general, solvents may attack some plastic par

We have a problem with our Unleaded wave solder machine only randomly soldering some pads. I have looked at the flux level and that appears fine aswell as cheking the preheat and solder height in the bath. The probelm is not exclusive to one perticul
