Does anyone know of any industry guidelines for the exhausting of volatiles in reflow ovens? I've seen some numbers like 1,000ppm for the oven atmosphere, but is this typical? My concern is the volatiles in my WS629 solder paste may be attacking th

Hi Dave, It may be. DI water alone will not build up residue. It can attack the finish of electro-polished (mirrored) stainless steel though. I have seen a white / chalky buildup on poly inline cleaners, usually isolated in the wash section. The

A simple question with very complex answers... But to simplify, you could start at this. Water soluble fluxes are cleaned using (typically) de-ionized water, using a spray wash method. Sometimes a saponifier is added to the water to help it get

Hi Dave, To close-loop or not to close-loop, that is the question� I can not speak for all machines, but in our case, close-loop systems are actually less costly to operate than open-loop systems (we make both). First, determine the volume of wate
