When you say all over the board, please give more detail. Where are they located? [All over wave soldered portion, laminate only, solder mask only, solder only, specific components only, etc] When you say white residue, what color are they really?

PAM uses precision cut black plastic parts against a white contrasting background why is this not acceptable??

What is this oxidation? What does it look like?

The parts adhere solder very well. It does not pertain to a certain part on the board either it is all over the board. I cant really say that it is oxidization all you can tell is that on certain parts of the pad still shows like white tin and that
