hi,

just a word of caution about grit blasting the pwb with alumina.  if there is any tin-lead plating (or equivalent) present, there is a strong chance that the grit will become embedded in it.  it has been my experience that the grit will be very, very difficult to remove.

Hi Jason,

You might try having them processed through an aluminum oxide blaster.  I
don't know about the documentation part of your question but I think you'll
find that a high-pressure media sprayer, like aluminum oxide or whatever,
will "matte" the surface without removing copper or damaging any feature.
