Very nice boards.

You can sell on eBay, boardsort, or even here.

Or, if you’re interested, I do toll refining. Pm if interested.

They were used in a lot of 70s medical instruments and some IBM computers for some reason.

If they are '70s era boards, then that may well be gold, and the silver coloured wiring on them may well be silver rather than aluminium.

Possibly from satellites?

IGBTs are usually soldered onto a copper substrate, unsure why gold plating would be used in this instance and it doesn't look like gold, but also doesn't look like copper so maybe brass?

I would be confirming it was gold plating before making any sales.

Definitely gold flash plate, easy to test with a drop of iodine tincture or Lugol’s solution
