Since OA flux residues are corrosive if not removed, how does one handle soldering rework wires to boards? Won't the flux wick under the insulation and cause a problem? Assume I do not have the option of using a no clean flux. Is my only choice an RMA chemistry with local cleaning (which is an option I have available if needed)? Any other ideas? Thanks.
