General question regarding circuitry components.

No sir, there isn't any practical reason for it to be there unless it is some kind of super high end board.... (i know non of these)
Some high greade computer cards have thin gold plating underneath the green slik screen, but definatly not found in any home appliances.

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.

As i said... there might be.

In my opinion, it's not really worth the time even in a hobby scale...
The plating is flashed and it will probably won't be so convenient (to say the least) to strip in a cell.
