Modular circuit board is the abbreviation of printed circuit board, which is a substrate for assembling electronic parts and circuit boards. It is the printed board of the point-to-point connection and the printed component formed on the common basic material according to the predetermined design. The main function of the circuit board is to connect various electronic parts on a board to interrupt the inheritance. The right and left of the circuit transmission function, which is why the normal operation of electronic parts cannot be separated from the connection of the circuit board.

　　 The circuit board is a key interconnection of electronic products, which is also a product of modern development. Circuit boards are also called the mother of electronic products, because in electronic products, our circuit boards are special. Without the circuit boards, the assembly of electronic components cannot be connected and assembled normally.

Circuit boards are used as sub-components and interconnected substrates for key electronic components. All electronic equipment and industrial products currently on the market need to be equipped. The industry chain and business coverage derived from circuit boards are quite extensive. Got. Involving general consumer electronics, medical technology, aerospace technology products and other fields. With the development of science and technology and the era of large-scale industrialization, the demand for various electronic information processing based on circuit boards is continuously increasing, which has also promoted The benign improvement of the circuit board in the development process. On the basis of continuous optimization, emerging electronics continue to emerge and develop, making the product use market of circuit boards continue to expand, such as our 5G era, as well as LCD, digital TV, cloud mobile phones and so on. With the arrival of the era of great industrialization, the market share of circuit boards will also be greater.

　　The circuit board is the basic component of the electronicization of the information industry. It belongs to the electronic assembly industry in the electronic component industry and is the basis for the development of the electronic industry. The assembly students of circuit boards also have very high standards. In our country, the assembly industry for circuit boards has been quite mature and is the benchmark of our current industrialization era.
