Sure looks like flux residue to me and I don't know how your bare boards could be causing that unless there's something on them when you get them, and that you would notice. I'd still be looking at my own system, blowers and exhaust lines. Do any of

to summarize - 3 components are placed on a single module x 8 on pcb - 2 anodes & 1 cathode are infected (so no component for us) - the problem does not look like wetting problem as the component and land pad is wetted, but the paste is not complete

What type of contamination is it? Flux residue or something else? If you are having contamination issues, you have a problem with your process. Simply washing the boards or using a roller may fix the problem, but you are treating the symptom, not

Thanks guys, But for the cleaning process we already have a chemical product to clean flux residues and other contaminant. But it seems that we can't rinse properly under low stand-off components and we find trace of our chemical under some ceramic c

@ Westshoredesign: Go take the top covers off your XPM's. Tell me if you see flux residue on the blower motors and the surrounding area. If you see this, grab ahold of the blower motor and rock it back and fourth. It is moves, the seals are melted o

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

While there may not be any specific requirement to cleaning prior to coating, cleaning an assembly prior to coating will only serve to increase the reliability and integrity of the coating. Some residues from low-solids fluxes can interact with conf

OK� Nap time�s over! Technically speaking, water soluble flux is just that, soluble in water. Technically speaking, one does not need a saponifier or any other chemical agent to remove water soluble (OA) flux residues. However, one must conside
