How to quickly estimate the resistance of PCB surface copper wire?
Copper is a common conductive metal layer on the surface of a circuit board (PCB). Before estimating the resistance of copper on a PCB, please note that the resistance of copper varies with temperature. To estimate the resistance of copper on a PCB surface, the following formula can be used. When...Read more -
