Jim, In most cases if you can eliminate a process you will save money. With that in mind, an all surface mount or all through hole design is prefered. There are alternatives to that rule, like hybrid designs that can be pin and paste soldered. It al

Steve, I agree with the recommendation to check the temperature. This is the first place to go. Is this an IPA or water based Noclean? What is the topside temp of the assembly at the effected areas? If you are too cold you will have a tendency to hav

I have found that preheating the solder pallets prior to use helps cut down on the solder balling. Also, we do not cool the pallets between passes and we use a spray fluxer because a hot pallet will knock down the head on a foam fluxer. We use WS f

Why are you placing Kapton dots on your board prior to wave soldering? * Prevent solder from touching the hole and the area around it. [If so, why do you need to do this?] * Prevent solder from flowing up through the hole and coating portions of the

You can also insert a stainless steel screw the size of the hole in the board before wave soldering, this will prevent the solder from wicking up to the top or close the hole (this is real cheap). I still remember the good old days using toothpicks t

Have you check the flux gravity lately? If not, Check the flux gravity every 6 hours to make sure proper parameters are meet. Here is a list of things that may cause your solder ball problems; Excecive heat, defective fixtures, preheating temperature

Hi everybody, We have wave solder fixtures made of Durapol and multiple wave solder machines. Most likely we�ll use the same pallets for either tin-lead or lead-free solder for a while (of course after washing the pallets). Should we test the palle
