Wondering how you guys do this.
Scenario: You have to rework a part (small IC or resistor) on a board that has already been conformal coated with acrylic.
What do you do with the post soldering residues before you cover it up with fresh coating? I know what we do, and I have never felt comfortable with the local clean and blot method.
I was wondering if a small vacuum existed, kind of like at the dentist office that could clean and vacuum at the same time? If not, i know what my next project will be!
