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 parameters adjustments...but to no help. I even reversed the direction of the board on the pallet, but the pin that comes to this particular edge of pallet starts having the problem. This tells me that the connector doesn't have a issue. Any suggestions?
