Initially PCBs were designed manually by creating a photomask on a clear mylar sheet, usually at two or four times the true size. Starting from the schematic diagram the component pin pads were laid out on the mylar and then traces were routed to connect the pads. If you have many questions of PCB Design, please come here!

PCB, short for Printed Circuit Board, is manufactured by electronic printing technology and responsible for providing electrical connection for components. Schematic diagram is the only principle PCB design has to stick to, determining number of layers of PCB according to complexity of schematic diagram and PCB size in order to finally implement concerning functions set by circuit designers. In terms of number of layers, PCBs can be classified into single-layer, double-layer, four-layer, six-layer and other types of PCBs with multiple layers. With the development of electronic technology, PCBs have been widely applied in all fields and they are planted in almost every electronic device.
