i was under the impression that a completely stripped motherboard was still gold printed. you can see the many layers when you look at the side, and there is gold plating on each layer to complete the circuits. thats what separates it from low grade board, the other stuff attached like ceramics, plastics and steel parts are actually holding the board back from being worth more than motherboard grade. i have no idea what the ratios are, as i do not refine, nor do i work with refiners.



can anyone tell me more about the gold printing process for layered boards?
