I think you have your pitch wrong but anyway, I have never had success with wave soldering anything less than 50 mil pitch. On a QFP I have had good luck on three sides of 25 mil but never all four sides and without defects. Mask 'em off and hand s

Square-leaded pin headers will typically bridge at the trailing edge (last couple of leads), since during peel-back, the solder at the trailing edge has "nowhere to go". If you have control over designs, ask your designers if they can put solder thi

I assume you are ref to top side wetting. In that case you may need to spray the top side of the board with flux to get it to fill. I would suggest ceaning the board afterwards. And yes you can rerun boards through the wave several times. Most pa

Kester has a special alloy for high temp soldering. Alloy 123. I would think that if you coocked 63/37 to 360c you would have a pot of dross in no time! Doug

If you have surface mount on the bottom, you can place openings between any thru-hole parts that constantly short. Your adhesive is a natural solder block!

What manufacturer is it? I usually stack the bars in as tight as possible. Especially against the wall of the pot with heaters. While it's heating keep applying slight pressure with a bar of appropriate material, towards the sides to facilitate melti

Hi Dave - You are correct that I was not clear in my comments. I assumed Joris had seen the usual solder balls accompanying his blowholes. Nevertheless, Joris, my first two recommendations still stand. Increasing the dwell time of your leads in t

I agree with RealChunks. The application of any of these "wave solder process control tools" is dependant on how the shop is run. At some shops, PM is inconsistent and slacked off on. At other shops, there is no technical expertise at the operator
