I tried soldering to several of the black pads and was successful, the solder stuck with no hesitation. so i guess this is not truly "black pad"? would that be a correct statement? What causes this blackening that looks like oxidation under the mic

There's background and links to papers on black pads in the fine SMTet Archives.

This is caused by PCB suppliers process. Search the fine SMTNET archives for this as it has been discussed many times. Russ
