A printed circuit board designer (PCB designer) plans the layout of circuits for products such as computers, phones, games, and other devices. As part of your duties, you use computer-aided design programs to create assembly drawings, which are then used by manufacturers in the production of products on a large scale. You may design anything from circuits, computer chips, to industrial and commercial components. Your responsibilities include rigorously testing all your plans to avoid malfunction or component failure, and you provide documentation that proves adherence to industry and legal standards, such as those laid out by the Institute of Printed Circuits (IPC). You also develop detailed specifications to guide the manufacturing process.
