Hi Alvin,
Colin Lea in the UK did quite a bit of work on this in the late 80's--a good
deal of it can be found in his book "A Scientific Guide to Surface Mount
Technology," Electrochemical Publications, 1988.
It is a time/temperature issue--how long before the IMCs grow through the
surface and affect solderability. Yo my knowledge, little has been done in this
regard with LF-solders.
I will touch on some of this in my workshops that I will be giving in
Singapore May 4 & 5--for more detail on this please contact Chua Eng Guan at
www.upstar.com.sg.
Regards,
Werner Engelmaier
