Hey all. Dismantling some antenna equipment and stumbled on some visually GREAT boards, but I am skeptical of their value.
Pic#1: Very thin board. It looks like gold weaving throughout the board...is it Cu?
Pic#2: Thick board. Side 2 looks great at first glance but when you grind it (look at middle), it appears to be Cu
Pic#3: Very thin board. Not much chip population. Unsure.
Pic#4: Similar to #1 where it looks fancy, but I'm skeptical.
Thanks for your comments/advice.
