Hello Techies:
Does anyone of you have a weird experiences on Sn-Sb alloy for
soldering? (Lead free)?

In my case i have a separation between a Cu surface and the SnSb (95/5)
after HTSL test at the intermetallic layer, in which i can't find any from
88Pb8Sn2Ag solder paste.

Is Antimony can promote kirkendall voiding during the Sn and Cu bonding?
If somebody uses 95/5 (Sn/Sb) for soldering, what are the usual problems,
your were encountering?
Does Sb affects Sn diffusion on Cu metal? If yes what would be the optimum
alloy composition.

Appreciate your help

regards

Jonathan
