All,
I was wondering how you go about putting nomenclature on copper surfaces
and subsequently processing thru immersion tin or immersion silver without
experiencing nomenclature peel? I have of course thought of the
alternative which is to process the boards thru immersion processes and
subsequently nomenclature them, however, our current inks require a long
cure time and very high temperature which artificially ages the finishes.
Thanks.
