If you are using a photo defined solder mask, you can control which
pads are covered/filled and which pads are cleared.

I have run into a problem with a board that has vias in smt pads. We
need all of the vias plugged, and I am told that solder mask is the best
way to do that. This is to ensure that a good vacuum is maintained for
our ATE equipment. That is the problem. I can not have a via covered
with solder mask on top of an smt pad. The board house I am using says
this is difficult for them because they have to determine which vias are
plugged and which are not. Anyone out there with any suggestions?
Thanks,
Barry Darnell
