Does anyone one have any suggestions on what containers to use to put the solder (lead) into? We used aluminum bread pans last time since we wanted to reuse the solder and that was not such a hot idea. It took forever to tear the pans apart to get th

I have Immersion Ag and Immersion Sn LF boards that were waved using SAC305 alloy. I have a lot of tears/shrink voids in the waved connections. I am aware that SAC305 in wave has a propensity of shrink tears/voids due to the non eutectic property of

Dear all, Referring comment from Mr. Jack,IPC director certification & assembly technology, the term "fillet tearing" is too broad. Cracks or fractures in the required fillet area, with SnPb or LF alloy and whether you call it tearing or not, is a D

Just to clarify: I'd say that it will potentially save money by turning the wave off at night, but the savings are minimal. But...If your power rates are cheaper during off peak hours (at night) like some power companies offer, it may save you money

Gaaaahhhh! NEVER mention man law and turning bottles of fine wine (metro law) in the same statement. You'll tear a hole in the time/space continuum.

The Technical Services Group at Alpha Metals has spent a fair amount of time looking at wave soldered Pb-free connections. We too have observed fillet tearing, fillet lifting, and pad lifting. I have concluded that without major changes in the mate

Find out the lead frame alloy. Cte mismatch can cause the same defect. Ran into this 3 years ago wave soldering with Tin-Copper.....okay, you caught me. I admit it. Wavemaster larry told me about this and I'm posting it under my name. Shameful, I
