Hi Technetters, We have now started dipping our boards, this is a BIG step down for you guys, BUT, its a big step up for us. The thing is the boards are giving us severe bridging problems. We are using Kester 63/37 solder and, #971 flux, foamed, with OSP coated boards. The pot is set at 460, and we have tried hotter and cooler, with the same result. There is a film that forms almost instantly on the surface of the moten solder which I think is the source of the problem, would working under nitrogen help to eliminate this? In fact is blanketing with nitrogen a viable solution? HELP!!!
