Hello Georges,
I actually read it as Werner referring to searching for long term
reliability "studies", which are still limited compared to SnPb studies.
All the best,
Jean-Paul

Sorry Werner I couldn't resist that response.

Hi Pete,
If you cannot find any studies on long term reliabliity assessment you
have
not been looking very hard.
There is no such thing as "the common mechanical stress induced BGA
corner
cracking"-there has to be an underlying cause, because that kind of
cracking at
assembly is not common.
From what you are saying, your company could greatly benefit from a
reliability consultant.
