Hi Werner,

Sorry that was the subject of the other e-mail that I just used its block to send my e-mail.I guess I missed it!Sorry for the confusion!

In fact I am investigating the finite element models to include the intermetallic layer, to me should have a significant impact on thermo-mechanical durability of the SAC joint. The change of the solder composition near the intermetallic layer due to metalization. 
Please correct if I am wrong!

Why do you subject this "Coffin-Manson"?
Coffin-Manson does not work for solder.
