BTW what solder cover are you talking about on sound blaster cards? I have boxes of new sound blaster cards.
I think he's talking about the green solder mask.
Solder mask or solder stop mask or solder resist is a thin lacquer-like layer of polymer that is usually applied to the copper traces of a printed circuit board for protection against oxidation and to prevent solder bridges from forming between closely spaced solder pads.
Wikipedia
Most circuit boards have copper under the solder mask but a few have gold. There are some display boards in in certain phones I scrap that have the gold under the solder mask which means more money.
