We are wave soldering a board having 24 similar thru hole connectors on it, using a wave soldering pallet. The problem is that one particular pin of connector in around 6-9 connectors get excess solder on the bottom side. I have tried all the parame

Presently many of our boards are wave soldered with 0603 chips on the bottom side, with soldering PPM level of 500 PPM. Apart from dispensing the glue we do screen print the glue depending upon the product maturity. My question is, 1. Can we print t

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 pallet w
