Thanks for all the suggestions, micro-abrasion works really good and its fast! I would also like to try the laser suggestion when I get some time.

Hi Tim! I was in the same position as you, except instead of just some pads, I had to remove mask from rather large areas over a ground plane for some RF components. Unfortunately, I think some sort of mechanical means (dremel tool, scraping, or micro-abrasion) is going to be the safest way. Any sort of chemical that is aggressive enough to remove cured soldermask isn't going to be very good for the board.

All, I have run into an issue with a board that has solder mask covering some pads. Is there a product/solvent that can remove the solder mask easily with out etching the copper? I would rather chemically remove it than manually scrap it off with a razor blade.
