PCB(printed circuit board) is printed circuit board, short for printed board, is one of the important components of the electronic industry. Almost every electronic device, from small electronic watches and calculators to large computers, communication electronics and military weapon systems, has integrated circuits and other electronic components. In order to make the electrical interconnection between the components, printed boards are used. The printed circuit board is composed of an insulating base plate, a connecting wire and a 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, which is conducive to the realization of mechanization and automation in the production process. At the same time, the whole assembled and adjusted printed circuit board can be used as an independent spare part, which is convenient for the exchange and maintenance of the whole machine products. At present, printed circuit board has been widely used in the manufacture of electronic products. [2] The earliest use of printed circuit boards was paper-based copper-coated printed boards. Since the advent of the semiconductor transistor in the 1950s, demand for printed boards has soared. Especially with the rapid development and wide application of integrated circuit, the volume of electronic equipment is getting smaller and smaller, and the density and difficulty of circuit wiring are getting bigger and bigger, which requires the printed board to be updated constantly. At present, the varieties of printed boards have developed from single panel to double panel, multilayer board and flexible board; The structure and quality have been developed to ultra-high density, miniaturization and high reliability. New design methods, design supplies and board – making materials, board – making technology continue to emerge. In recent years, a variety of computer aided design (CAD) printed circuit board applications have been popularized and promoted in the industry, in specialized printed board manufacturers, mechanized, automated production has completely replaced manual operation.
