You should probably contact your board shop and explain what you are trying
to accomplish....

Good luck!

Subject: [TN] How to Bake FR4 Boards

Dear Technet:

Can someone tell me what temperature and duration
we should bake some unpopulated FR4 (HASL) boards?

We are attempting an experiment to see if we can "bake" a
potential problem out of certain boards, but we don't know
what the baking temperature / time should be.  The potential
problem we are looking to bake out is under cured laminate
which could be causing a hook problem.

Please help.

Kaye
