Hi Walter, Do you refer to a sprayfluxer operation? The problem seems to be a parameter setting issue. 1. Ensure the wide angle spray reaches PCB with optimum jet pressure. You could pass a glass plate to understand flux coverage and view Jet pressur

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

slowing-down the conveyor to allow the solder to heat these balls more. But that may not be the answer, because if the flux is exhausted, more heat will not help. Then if the flux is exhausted, the answer is to crank the belt. Two different answer

Do you mean in a reflow oven or wave solder? if so check your exhaust blower, make sure its still drawing. if not the flux/dust that builds up on the exhaust pipes may be falling into the machine.
