The printed circuit board (PCB) is at the center of nearly all electronics products in the 20th century. PCBs originally consisted of wires placed along paths connecting a series of components on a rigid board — these were deemed printed wiring boards. Eventually, the printed wiring board morphed into the circuit boards with conducting strips etched into multi-layer boards that we see on PCBs today. The PCB industry is associated with nearly $1 trillion in sales of electronics each year [read more at: "Printed circuit board industry"]. Thus, it is important for engineers to know at least the basics of PCB design, even if the manufacturing is outsourced to companies. In this tutorial, we will introduce the design of a simple PCB and the process required to get the PCB manufactured by a company called NextPCB. Their process is simple and easy, and even allows the engineer to view their design on their online gerber file viewer.
