Why do motherboards (and other hardware) look like they look? What are all those little nooks, holes, or ‘wires’ that seem to be almost painted on?
I understand how binary data works – ones and zeroes and all that, but I can’t find an explanation about this. I’m uploading a picture for reference – the area in red contains a white line. What are those lines, do they do anything and what? Would scratching them actually do something?
Thanks alot in advance!
