Could be a long shot, but there are ICT probes that are very sharp, even
that twist as they are depressed.
Usually for probing 'non-ideal' test pads. I don't know if they are
aggressive enough to break through the mask though.
Could be worth suggesting to your testers.
(I'm assuming that there is a large no of boards involved here, and the
scalpel blade method would be too labor intensive. Otherwise, happy scraping.)
