Dave:

Stripping Solder is MUCH slower than stripping Tin, which is what they are
used to doing, so, I would watch carefully to insure that all the solder is
gone, especially in the holes.

I HOPE they intend to do this is a spray, conveyorized system, not in a tank,
the potential for excessive Copper attack in a tank stripping situation is
large, if they use the typical Nitric/Ferric Nitrate Tin/Solder stripper.  If
they use the older Ammonium Biflouride/Hydrogen Peroxide based stripper,
potential for Copper attack is minimized greatly.
