I was thinking... epoxy coat the whole board (except your sensors). Then, put a second coat on and press a layer of aluminum foil into it (with suitable cutouts). Then a third coat on the outside of the foil.
Overkill, perhaps, but it should block all light and chemicals. _______________________________________________ geda-user mailing list [email protected] http://www.seul.org/cgi-bin/mailman/listinfo/geda-user
