I would suggest the Hysol 50-000 series Cat-L-inks, two part heat curable
epoxies for screen printing (although we also stamp and hand letter). Suggest
the 45 or 77 catalysts. For surface pre-treatment we allow light abrading but
usually just an acetone or IPA cleaning is sufficient (just prior to ink
application, then dry then apply ink).

I need to implement ink marking on nickel and gold surfaces for IC
components. Can anyone advise me on,
a. Type of ink (for pad-mark)
b. Surface pre-treatment process
that would ensure that the ink would meet the MIL-std mark permanancy test
requirements ? Appreciate your expert advise !
Thanks
