Are you talking about small 'volcanos' that burst through PTH solder connections? If so, you have moisture outgassing through the PTH barrels: * Plating on the hole of your bare board is too thin. It should be greater than 1 thou [25um]. * Your bak

If you eliminate this test, how would you monitor the cleanliness of your: * Bare boards * Components * Processes You probably could get a c of c from your board fab, but a c of c from the component suppliers would be burdonsome [and agruably useles

I am looking for data / info on how flux may contaminate the solder in a Wave. I have a customer who requires a no clean process. Our wave is equipped with 2 separate fluxing systems and I would like to use OA in one and the No Clean in the other. Th

I have chceked the fluxing application, I seem to be getting good consistent coverage across the board using our foam fluxing system. Good flux penetration on the top-side of the through-hole plating, as this was checked using a fax paper.There is no

Hi John, It depends on what equipment and resources you have at your disposal - if you have an antique wave with crap adjustment & hand sprayed flux, no debridging/air knife system on a tightly packed board with a multitude of fine pitch connectors
