I agree with Russsel.
Immersion Gold over electroless nickel should be adherent and should not peel
during tape testing.  As a supplier we recommend testing the immersion gold
adhesion as a QC in process test for ENIG.  Peeling of Immersion gold in most
cases is an indication of a compromised electroless nickel surface.
