RCC is a copper foil coated with B-staged epoxy resin.  Is it possible to
etch a pattern in the copper while the epoxy is still in the B-stage?  In
other words, will the chemical etchant attack the as yet not fully cured
epoxy?  If anyone has actual experience doing this, please let me know.

Thank you,
James High
