Subject: hole not to spec for compliant pins


To all,
 I have a test board, that is gold over nickel, and .200 thick.
The problem I have is that the holes for the compliant pins should
have been drill at .045, and plated down to .040. The holes however
have finished at .045. (hole count is 1456)
 The range that the assembly house can live with is .040 +/-.003.
 I would have to somehow replate the barrels of the holes
with a minimum of .001-.002 mils to get within the compliant pin spec.
 Soldering the pins in, is not an option.
If anyone has seen this problem before, could you please respond ASAP, with
any possible solutions, or the name of someone who might be able to fix
these boards.

Thank you,

Loren Hendrix
