There are pots on the board in the power supply to adjust the voltages after the machine is powered up. The location of these pots are in the munual supplied with the machine

Something on the 5v side is pulling it down. I would check every thing associated with the harness you are disconnecting. Your shorting somewhere! Don't have a schematic in front of me. Also look for leads getting into the backside of your connecto

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
