Ken,
I was considering the same situation a couple of years ago and asked the
same question in this forum.  Essentially, the answers indicated that the
older, single-reflow OSPs have been used for years (10+) in many
applications with compliant pin connectors with no problems, but that there
was not much data on the thicker multiple-reflow OSPs (which was being used
for the applications I was considering).  In the absence of this data, we
did our own testing (including shock/vibe, temp cycling, temp/humidity,
high temp tests) and found no problems.  Similarly, there have been no
problems with this combination on live products since introduced a year or
two ago.

I'd echo the point about ensuring that the fixturing and backing plate
being sound before proceeding.

Regards,
