Hey, Mike,

I bet you are talking about the paper by Al Gickler at SMI '97.  I was 
the chair of that session and was happy to get that paper from Al.  But 
the audience was less than appreciative.  Their comments were that the 
information was too elementary and non-discriminating.  I think it was 
simply about two years ahead of its time.  Al has done some of the "dirty 
work" that needs to be done to test lead-frees.  He found, not 
surprisingly, that lead-free compositions, already saturated with copper, 
did not pick up additional copper in simulated use.  No surprise, I 
guess, but someone has to prove it!

Re: reliability testing-  check back thru the archives of this forum, 
especially for some of the European comments, where they have some 
experience testing lead-frees.
