I've been involved with no-clean flux and conformal coat in the past.It has been my experience that the amount of no-clean flux used is proportionate to how well the conformal coat adheres to the boards.No clean paste did not affect adhesion. The co

My company currently uses water soluble paste for our SMT process. We were having trouble retaining hot water in our in line, closed loop DI cleaner. The cleaner kept shutting down when the water temp. dropped below 125C. As a result, the conveyor

Where I'm located, we call it OCC. By any other name would it smell/stink as sweet? I need to know, though it's been overworked, who has experience with OSP and its compatibility with water and IPA no-clean, VOC no-clean, and device adhesives

Hello Netters, I need some info, Earl or Dave, I have a PCB that exhibits a white layer on solder side. It does not appear to be surface residues (IPA has no effect), but looks like its under solder mask. My first guess is that the LPI solder mask
