Ioan,

We use Conformal Coating Removal Pens made by Trace Technologies and distributed by Tech-Spray.    They are self-contained press tip pens that are about 4"x1/2" contain 12.5 ml fluid and have a wedge shaped felt tip, and we uses either Qtips or Foam tipped swabs to remove the duff.     Their website is Techspray.com the part number is 2510-N, the material is also in bulk.    You can maybe mix your own the chemicals are listed.    We purchased some in bulk but the pens are easy, exact, and disposable.

Dear Technos,

We need to locally strip the acrylic coating (1B31S) from a few components, on a few thousands of boards. Right now we're using Q-tips to do the rubbing and, besides having to pluck tons of fibers afterwards, we're also going through a lot of Q-tips.

So the question is: is there anything else we can use, that will be more effective, cleaner and more economical?

Thank you,
