Hello, We are buying a Vitronics-Soltec wave solder machine with a spray fluxer to replace our old Econopak that has a foam fluxer. Currently we thin our flux (Kester 951) in the foam fluxer per Kester PS-20 and PS-22 test kits with kester 110 thinn

Besides changing fluxes, do you have good knowledge of actual flux volumes? Do you have a micrograms per square value? Pre-heats can affect flux by burning off too soon and also not enough - therefore moisture hits the wave- how's your humidity cont

Don, thanks for the thoughtful insight, can I run some thinking points for your further assistance? 1) ours is a Au over Ni PCB bareboard. Do you think excessive Au thickness is any way a influence for poor solder formation? I did notice the PCB ba

Several points are: * There can be a seasonality to the venting of [smells emanating from] wave solder machines, because the heating and cooling of your plant changes with season. * Supplier's specification for your wave solder machine defines the pr

I wouldn't think so, A thermocouple can be attached to the lead that is being soldered. Russ
