Hi ! Try fresh DRY solder paste... Keep solder paste in a sealed container until the moment of use. Humidity absorbed by the soldering paste becomes vapor violently at the moment of heating it , expelling the solder in form of balls everywhere.

Sure you can do it!!! Just so that I'm clear on your inquiry, the pattern you're talking about is what? * Foot print of the copper pads * Glue pattern for printing your adhesive

We have seen this type of problem. After eliminating possibility after possibility we corrected the problem by throwing out the glue and starting fresh. It was not expired, just bad for whatever reason, we could not asertain what went wrong with it.

I recently purchased a cleaner. I have made great efforts to find a Flux that will not cause this closed loop cleaner to foam. The last was a Neutral WS flux from Alpha Metals but it still foams. This foaming is happening after wave solder.

We too had a problem with the WS609. We have since switched to Alpha's WS619 (same formula with an anti-foaming agent) This really helped but we still monitor flux application and try to minimize wherever possible. Chris
