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

We're trying a selective soldering pallet for the first time with mixed reviews. Are solder balls a prevalent problem with this process? Most of them seem to correspond with pallet wall locations....is it too much turbulence from the rotary chip wav

If you can, attach athermocouple to the locations where you are getting solder balls. A previous product I had showed the same thing and we found that we had inadequate preheat leaving the liquid flux to splatter when it hit the wave. It could aslo

Jim Consider issuing a purchase order to your assembler for the purchase of selective wave soldering pallets required to solder your board. That way, you: * Own the pallets. * Can take the pallets with you should you decide that another assembler

Steve , I agree with all the responses you have received. Randy Villeneuve is absolutly correct in all of his assesments and I would consider him an expert with the process , Gris is correct about adding a "heat sink" to the process complicating pr

Hi, Try to check if there is water absorbed in the flux or the humidity around the wave area. possibly plating on barrels that might be damaged?

This might be a trival mundane suggestion but try to use non conductive plate to hold components. Probably even made of the pallet material. I am sure your pallet fabricator will have tons of scrap and he can help you find one. T

By the way, what type of preheaters do you have? IR? Convection? If you have IR, there may be a way to cheat. Vince W

What kind and what brand of gloves are people using for handling hot wave solder pallets? My operators are going through a pair a week. I need something better. Thanks
