Patrick-
You may also want to refer to the cover story in the May 1995 issue of
SMT Magazine, "Optimum Processing Prevents PQFP 'Popcorning' ," p39,
by P. Yalamanchili, R. Gannamani, R. Munamarty, P. McCluskey, and A.
Christou of the CALCE Electronic Packaging Research Center of the U.
of Maryland.

I could use some assistance in defining 'popcorn effect,' delamination,' and
'floating' as it applies to components (BGA, fine pitch packages).
Any other known common component level phenomena (seen during
assembly/soldering) and words used to identify them would be much appreciated
as well.
Thank you,
