Printed circuit boards

Printed circuit boards can be produced by a laser printer, and can even be made with carbon-based compounds.^[1]

They are not yet competitive in cost and functionality with mass-produced circuit boards, but they offer hope that computers can be produced without mining, and in particular without conflict minerals^W such as tantalum.^W
