First of all, my Customers can be described as a real "Jack-Ass" or at least the SQE does. They don't treat us as their partners OR more like "do what I said...When I started to use solder paste you probably weren't borned yet and/or probably still o

| | Hey all! | | The wave solder warrior is back. I have found a flux which leave almost no residue (the least yet), but because of its super low solids content I absolutely cannot get topside fillets. The multi-layer, two sided board is on a

Why are you guys not simply switching to No-Residue?? Residue free soldering is not a dream, it is a reality and is succesfully implemented for over a decade. I am the founder of no-residue technology, a technology developed to effectively compete w

If it's what I think it is you have a white residue on the legs of some of your fine pitch parts. We have came across this problem some time ago the way we eliminated this problem is to make sure your w/s solder and your liquid flux is compatible.

Hi Steve, What type of flux? How do you apply it? What kind of wave? Rite off the cuff, I'd say you're applying too much flux, but without knowing a little more, it's tuff to say. It could even be board related. Hate to see what WML has to say

okay so both the 2005 formulas from interflux are clear alchol based fluxes. Yellow res huh? In looking at the temps here, I would say you might be too hot at both preheat and solder temp. You may be burning flux. How long is dwell time over wave

We recently changed to an Amtech no clean paste and flux that is washable. So far excellent results. Far superior to the water soluable paste we were using. Fewer solder balls, longer life in printer, boards can be left up to 5 days and still come

Good Morning WS, If you experieced the solder balls after reflow of a bare board through the oven, then the source of the solder is either the oven or the board. I have had boards with untented via's that were HASL'd that had entrapped solder and fl
