FYI....

There are immersion Tin chemistries that have no MSA (Methane Sulfonic Acid)
and operate at much more benign pH levels...like 2.0 +/- instead of the MSA
pH close to Zero.  And these other chemistries tolerate dissolved Copper
better.

Contact me directly for infomation on how to find these chemistries.
