What kind of circuit board IS THIS?!?!?! It's clear, thin, and has black tracks...Can I solder to it?
Hello, just working on another paper pinball machine xD This time, I am looking to make a home made score system using a calculator. When I opened it, it had a clear, thin, cellophane-like plastic circuit. it has black, powdery tracks with small holes to transfer power to the other side... what is this? can I some how attach more wires to these tracks? they are about as thick as a No. 2 pencil lead (not sharpened) any help would be GREATLY appreciated
