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.

Subject: [TN] Solder Mask Solvent?

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.

 

Thanks in advance,
