John,
The way we determine dry film resist adhesion after developing is with a
cross hatch test of the exposed resist followed by a tape test.
The method is ASTM Designation: D 3359-87. The tool for the cross hatch is
from Paul Gardner company (305-946-9454). The results depend on the
characteristics of the resist being tested. Some resists chip off more than
others in the cross hatched area. It depends what you are looking for from
your selected resist.
