Brian is right....and I am not sure if hot phenol would work, AND I DO NOT
WANT TO FIND OUT.  Cured epoxy is much more chemically resistant/inert than
FR-4, (and don't even ask about polyimide) which is why we could not strip
the old two part screened on soldermasks..so even if you could "strip" it,
and I am not sure that term is strong enough...the board would be history..

Then again, if you positioned the boards in the path of the Mir...?
