Protel Concise Tutorial Printed Circuit Board (PCB), also known as printed board, is a basic component in electronic products and appears in almost every electronic device. PCB can provide mechanical support for the fixed assembly of various electronic components such as integrated circuits, realize the wiring and electrical connection or electrical insulation between various electronic components such as integrated circuits, and provide the required electrical characteristics, such as characteristic impedance, etc.; PCB can also provide identification characters and graphics for the insertion, inspection and maintenance of components; in addition, PCB boards can be directly used to make components, such as antennas. The actual manufacturing of PCB is completed in PCB factories. The factory does not care about the design. Designers generally only need to hand over the undesigned PCB board drawings to a special factory, and the factory will make them into real physical boards. Here is a brief introduction to the structure of PCB boards, which will help readers better understand and design PCB boards.
