I am looking for an etchant that will remove a 1000-3000 ? layer of nickel
chromium (NiCr).  If you know of any or have a recipe for one, please let
me know.  The most desirable NiCr etchant would not harm a 5-10 um layer of
high temperature electroplated solder.  I have only tried a couple of
different chemistries, and neither is able to do the job.  I am willing to
try any chemistry.

Thank You,
Dennis Fall
