Inge,
From all I have seen, the P does not get into the IMCs—it simply concentrates at the IMC/Ni interface as the Ni disolves in Sn—there is actually a name for this: "Black Pad." ;-)

Werner,
what is your opinion about P-rich SnPb IMCs, how strong and reliable are BGA solder joints which suffer from this disease?

With alloys like these, who needs IMCs?

Werner,
what intermedals are formed in Vancouver? USA and Germany > US32/D26 and
finally D38/US33?

Hi Inge,
No, they form some nice crystalline plateletts, just like AgSn and
AuSn-IMCs and just like them lead to solder embrittlement in sufficient
concentration. I will be publishing a column on it in Global SMT &
Packaging in about May or June.

Hi, did not know of Tin/Palladium IMC. Thought they formed an alloy.
