853-049542-173 LAM Printed circuit board, or printed board for short, is one of the important components of the electronics industry. Almost every electronic device, from electronic watches and calculators to large computers, communication electronics and military weapon systems, where there are electronic components such as integrated circuits, uses printed boards in order to make the electrical interconnection between the components. The printed circuit board is composed of an insulating base plate, connecting wires and a welding pad for assembling welded electronic components. It has the dual functions of conductive circuit and insulating base plate. It can replace the complex wiring, realize the electrical connection between the components in the circuit, not only simplifies the assembly of electronic products, welding work, reduce the traditional way of wiring workload, greatly reduce the labor intensity of workers; And reduce the volume of the machine, reduce the cost of products, improve the quality and reliability of electronic equipment. Printed circuit board has good product consistency, it can adopt standardized design, conducive to the realization of mechanization and automation in the production process. At the same time, the whole printed circuit board can be used as an independent spare part, which is convenient for the exchange and maintenance of the whole machine products.
