Victor,
I did - when I was at Nortel in the 1990s. But I don't have that info now,
but I CAN say I NEVER saw a lead fail when it was pulled out of eutectic
tin/lead solder from a 62 thou thick board. And here at Blackberry, I have
never seen a USB through hole lead fail when pulled out of SAC solder in
boards around a mm thick. The solder always gives way first. I cannot tell
you what the numbers are, but I can say that any executive, sales person,
etc. who thinks solder is a really good meahanically robust material is,
well, a tad WRONG!!
Regards,
Bev

Subject: [TN] Leaded component, lead pull test
Fellow TechNetters;
Does anyone have information on the following:
Finish hole size, lead diameter, solder type, thickness of
board and lead length. How much force does it require to pull out a lead
from the solder joint. Will the lead come out cleanly or elongated and
snap,
Victor,
