We have a Seho wave soldering machine and cannot seem to get rid of dross that is being generated within the solder pot, and is being pumped out in the wave. It is not the same kind of dross that forms on the surface of the solder pot(this is very m

Robert: Several points: 1 Dross is a mixture of various things with no "fixed" composition: � The obvious things are metal oxides mixed with metal and this can vary in color with temperature and composition - remember some intermetallic oxides form

Hi Melissa, We mount this component in the bottom side with adhesive epoxy and the solder is done on the wave solder machine. During the wave solder machine, we have the problem as like the picture.. no solder in one of the pads...

Hi Manoel, I want to make sure I understand what you are talking about; reading the reply,along with your replys it almost sounds as if we are not talking about the same thing. In your picture I'm seeing a SMT diode correct? You are talking about th

Help!! Just got some new wave solder pallets in house. The pallets are 12 by 8 inches solid composite, with only two 1/2 inch by 1 inch spots cut out for the connectors. When they go over the wave, the solder wants to cling to the bottom of the pal

The pallets are made of a black composite that is 5MM thick, and yes, the bottom is beveled to the cut out space for the connectors. The wave solder machine is a Treiber, so the wave height is hand set. I always aim for the center of the leading edg

Charles: Here are a few possibilities you might want to check: 1) Conveyor width -- if the conveyor is too tight this will cause the boards to buckle as they go through the preheat section. We recently had this happen when we changed operators. 2

Hi, Are you coating the bottom of the palette with flux? What's the material of the palette. I have not seen that, but we did have some weird problems when we did not add flux on a virgin palette, but once it dirtied up a little it was ok. We had

We have tested SN100C and SAC305 in our selective solder machine (Ersa Versaflow). We wanted to test both alloys in the selective first because the investment in filling the pots is minimal. In our initial tests the SN100C alloy appears to be the bes

Armando, Is the problem in the same spot on the board with every run? If so, there might be something about that particular location that is part of the cause (ie. ground or power plane connection). It sounds like you're seeing blow holes, or insu
