| | | All y'll: I could use your input on determining when to skim dross from a wave solder pot. | | | | | | On one hand, dross protects the surface of the solder from oxidation. On the other hand too much dross may affect solder joint quality. O

| For some as yet unkown reason, we have started to have some boards sag and go under the wave. The boards are surface mount top side and conventional components wave soldered. We have checked the wave hight and both the profiles on the wave solder a

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

| What are the factors that go into determining PCB Board temperature requirements for the Wavesolder process? Most of the recipes I've seen call for preheating the PCB to around 230F - 250F. This temp is about 210F - 230F below the typical solder te
