Technetters:
I'm looking for information on the best way to confirm cure on a polyimide
board.  The particular part is a sequential lamination structure.
My questions include:
1.  Is the best time to confirm cure of polyimide immediately after final
lamination?
2.  Do the polymers created require a specific cure test, e.g. is TMA best,
DSC, or other method?

Also, can overcure be a problem with Polyimide?

And, does this material offer special challenges with respect to gel time,
resin flow, etc?

I've already heard differences of opinions, and am looking forward to more
avenues of knowledge from Polyimide experienced folks.
