Hello all,

I was wondering if any of you have worked on etching Ni-Fe. I am currently
using Ni Etchant type 1 from Transene and it gives huge undercut during
etching. Undercut is close to 10 times the actual thickness to be etched.
Does anyone have experience etching Ni-Fe with any other etchant with
minimal undercut?

Thanks,

Pavan Samudrala
