We had a similar problem with gold contact pads. Cleanliness is paramount. If you are using foil tensioning system, wash the foil in a stencil wash before use as the cardboard cassettes may be contaminated. Be very careful when loading into a frame f

Degeaser isn't a good chemical to use either cause it leaves a residue so don't use it. alcohol works good. Not sure why everyone thinks it blows up. heck i remeber back in the day when I hade 24 inch foam fluxers bubbling flux and alcohol (IPA no

Masdi, Try board shunts. They are hi-temp rubber strips with grooves cut. They can be popped on and off with ease and are much faster than taping and considerably cheaper. They also work great for masking goldfingers prior to wave soldering. Contac

| Hi, | Need some advice on how to eliminate or reduce the solder on finger that we are having right now. So far what we understand is that 90% of the problem is due to the reflow process where solder traps in vias causing explosion when subj
