Introduction Printed circuit boards (PCBs) form the backbone of electronics. They provide the platform to mount and interconnect electronic components using conductive copper traces etched from copper sheets laminated onto a non-conductive substrate. PCBs come in many configurations based on the number of conductive layers and type of substrate used. In this article, we will…
