You can try a 5% solution of sulfuric acid. It's used to clean copper foils to IPC-TM-650 method 2.3.15 prior to testing for purity.

We tried light sanding but we still have to find out the proper way not to sacrifice the evenness (surface level) of the surface. The flatness of the surface is a requirement.

can anyone share how copper is being cleaned a a PCB Fab House prior to applying HASL? thanks

Like Dave said, you need to use an acid solution. This is what is used prior to HASL. You will think I am crazy but you can use vinegar or even catsup/ketchup. The acetic acid will clean the oxidation. Just rinse the board off before using.

We do this sort of thing for a living, provide cleaning materials to clean things such as copper. If you'd like we can chat off line.

The US military no longer approves repair processes. What coating material are you aiming to remove? Choices for stripping are: * Chemical solvents * Heat * Media
