I was beginning to figure that there would only be gold plating on exposed parts- no need for superior resistance to corrosion when covered in that green. As far as the circuits I have been collecting go; They have all been from computers. I took apart 1 dvd player and was disappointed as far as prospecting it went. I have about 3 computers right now- 2 are scrapped and the final one sort of houses the most valuable circuits. The rest of the boards are in a bag.
Would you know if perhaps there is a bit of gold underneath these boards silk screen, and if regular electroplating would remove it with no further steps?
*edit- I also have the screen circuits of 2 laptops- and the entire circuitry of 1 laptop. 1 Modem with unfortunately very little gold save for the pins.
