Introduction

A printed circuit board (PCB) mechanically supports and electronically connects electronic components using conductive tracks made of copper laminated onto a non-conductive plastic. The PCB reduces the amount of wires in a device and inherently makes any device more reliable. The step by step instructions will describe how to troubleshoot your PCB.
