In answer to your question regarding the overcured boards, you need
to be concerned also with the adhesion of the solder mask and
breakdown of the solder mask. Regarding the laminate, an increased
cure should not affect any of the electrical properties you mentioned.
Copper peel strength could be degraded, and flex strength of the
laminate will be affected.
The fire retarding properties will not be affected because the fire
retarding properties come from inert ingredients added to the resin.
There is a covalent bond between these ingredients which will not be
broke by over-curing.
