【英文介绍】

 853-049542-173 PCB circuit board is one of the important components of the electronics industry. Almost every electronic equipment, small to electronic watches, calculators, large to computer communication electronic equipment, military weapon systems, as long as there are electronic components such as integrated circuits, 853-049542-173 PCB circuit board in order to make the electrical interconnection between the various components, must use printed boards. The printed circuit board is composed of an insulating base plate, a connecting wire and a welding pad for assembling welded electronic components. The 853-049542-173 PCB circuit board has the dual role of conductive line 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; It also reduces the volume of the whole machine, reduces the cost of the product, and improves the quality and reliability of the electronic equipment. The printed circuit board has good product consistency, and it can adopt standardized design, which is conducive to 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 product. At present, printed circuit boards have been extremely widely used in the manufacturing of electronic products. [2] The earliest use of printed circuit boards is paper-based copper-coated printed boards. 853-049542-173 PCB Circuit board Since the advent of semiconductor transistors in the 1950s, the demand for printed boards has risen dramatically. In particular, the rapid development and wide application of integrated circuits have made the size of electronic devices smaller and smaller, and the circuit wiring density and difficulty are increasing, which requires printed boards to be constantly updated. At present, the varieties of printed boards have developed from single panels to double panels, multi-layer boards and flexible boards; The structure and quality have also 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 application software has been popularized and promoted in the industry, in specialized printed board manufacturers, mechanized, automated production has completely replaced manual operation.
