Hello again,

I am having a little trouble identifying these boards. A few came from laptop mouse tracks, others from network switches, and the hardest for me to ID are the boards located behind touchscreen monitors. As you may see on the picture, these come with a big sheet of gold laminated material attached to a small board. Would you separate them or leave them together? Are they different grading?

Thanks for whatever help you can provide!

Lost in board scrapping... Natalia

A) switch is telco. Little one peripheral
B)board with tm trans modules is mid grade. Rest peripheral

Thanks a lot!

I just noticed that I never posted the picture of the piece I took from a touchscreen monitor. What a dummy, lol... I am listing it now to see what you think.
FYI, the entire gold laminated sheet is attached to the tiny board. Do you think I should separate them? If yes, would they have different ratings?

Thanks a million!
Natalia

the board itself is peripheral. The sheet is (almost) certainly copper. I've never come across one that was gold. Silver, tin, nickel, even brass. But not gold.
