Joseph, What is the topside temp reading of your board before reaching the pot? Do you have top-heater in your wave machine? It sounds like; you got an insufficient per-heating issue.

SAC305 has a liquidous state temperature 217 degC. Check the datasheet to compare to this temp. I suppose, it may be lower. - Cheers !

Joseph, In addition to my previous post The reason why the cracks are most visible at the transformer location is due to the weight of the transformer. The stress on the boards is the highest because the weight of the transformer will warp the board

Bob, Great theory if you're selling SN100C, but I have to disagree that an alloy being 4�C off eutectic will cause cracks. When a solder joint exits the solder wave, there is an immediate drop in temperature of 100�C. so being off 4�C is irrelevant.

On an ACE KISS machine we could program a drop in Z height to give a peel off angle after the component was soldered. Usually not necessary as the solder at the nozzle is falling away from the lead down the nozzle. If possible, we would program a fr

Can anybody tell me what kind of anti-seize compound to use in a lead free solder pot? I have found copper, nickel, and silver anti-seize but I cannot decide which one to use. Thanks for the help.

We have a Vitronics mySelective machine (model 6749, or "the Fat Bastard" as we affectionately call it). It's configurable with various combinations of "select wave" and "multi wave" pots. Ours has one of each. The "select wave" is for the most pa
