Wait a minute I thought I said Celestica and a few others have done the Engineering evaluations on a list of 10 top solder paste's and Indium SMQ92J and Kester's R560&562 came out on top. First you say 'don't trust all of the so called experts on thi

It seems familiar, but nothing that I've actually experienced. I've read some articles about tin-whiskering in lead-free solder. I think NASA has some pretty good analysis (or, at least they did a couple of years ago). The summary is that without
