I have an Ersa Versaflow selective solder machine (single bath) which runs via a Profibus control system. I have checked all of the settings on the inverter, and all of the connections and outputs throughout the machine, but the machine returns a 68

You should also remove all the pump parts and clean them, checking the bearings and seals. Clean completely the parts that allow the solder to flow back into the pot; ours have a spiral that fills with dross. Treat yourself to new nozzles. Tinning

John, We regularly wave solder electroless silver finished boards (Alpha Level)with mixed SMD and through hole parts and do not have any problems. We have changed a number on PCB's from HASL to electroless silver, mainly for the benefits at SMD whe

| Dave, | Sounds like you have material issues. Been there, done that. Tried 'em all. The best, longest lasting material I've found is called Durostone. It's made by a Roeschling, and most of the big fixture cutting houses now offer it as an option
