Randy,

On the Fab boards it would be relatively easy to have a laser ablate the
solder mask opening. Also depending on the component height the laser could
be set up for them to.

Hope that snippet helps

Subject: [TN] Solder Mask Removal

Hey y'all,

We have several hundred boards that are supposed to have  the solder mask
removed for around a mounting hole on the back side of the board.   The
fab house missed.  We are faced with a total remake if I cannot find some
way to remove the solder mask relatively easy.  Most are still fab boards,
 but I do have some that are assembled.

Any ideas would be appreciated.  The clear area has to be approx 1/2 "
dia.  (is for grounding)
