Dear all,
I have an electroplated thick structure (20 - 200 microns) containing Ni =
and Cu on the same substrate.=20
Does any body know the following etchants:
1. Cu compatible Ni etchant (etches Ni but does not attack Cu).
2. Ni compatible Cu etchant (etches Cu but does not attack Ni).
Any help are really appreciated.
Sincerely,
