Ron, only one way to know :
solder both alloys in identical process on identical substrates/pads, etc.
any variations of cooling profile (just to mention something)
will influence readings on crystal formations = strength .
Answers are infinite, variable, customizable, ..............>>>>>

Hook your trusty puller on it ; compare :
you'll be home in one day with full validational base ;
spending one more day on documentation .

Beauty and shear strengths are only and always in the eye of the beholder
(As Werner may tell you as well ; if he digs himself out of his favorite
sandbunker)

Subject: [TN] acceptable solder joint shear strength?


Does anyone know what the minimum acceptable solder joint shear strengths
are for Sn63/Pb37 and In50/Pb50 ?

We are trying to optimize our soldering to gold interconnect process and
need some baseline/ industry standard numbers.

Thanks
