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

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

We'd like to see pads on the board that closely resemble those on the interposer.

| We are in the process of getting into no-clean paste and fluxes. One important issue in this is sodler balling. I have heard some people say that having a matte finish would help in having lesser solder balls and that the solder balls would not b

Unfortunately it's nc or we'd be worrying about this on the fly. Non-contact is defintely and issue....this is an 18"x9" board with 1500 bottom side SMT parts that are scattered among the through-hole and vice-versa. We're currently using 7 hold-

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

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?
