TechNetters,

J-STD-006 has a series of 'high temp' SnPb alloys (some with Ag) that are close in SOL/LIQ temps. I'm familiar with Sn10Pb90 as a common high-temp ball on ceramic BGAs, but I haven't seen the others used. Are there any differences (e.g. mechanical properties) among these that would drive selection, other than the SOL/LIQ?
Are some alloys more readily available than others?

Ben
