Fellow TechNetters:
Can anyone shares their experience with SnPb solder etchant, I want
to decorate the solder fillet to search for
potentials fractures after a Post reliability environment. SnPb is soft
and I don't want to overlook artifacts due to
smearing during the final polishing process. Once upon a time in a
previous life a co-peer instructed me to used a
Buehler Final Masterpolish with a pH of 9.
Victor,
