PCB (Printed Circuit Board)

PCB (Printed Circuit Board), the Chinese name for 印刷电路板, also known as 印刷线路板, is an important electronic component, a support for electronic components, and a carrier for electrical connection of electronic components. Because it is made by electronic printing, it is called a "Printed" Circuit Board.

PCB (Printed Circuit Board), the Chinese name for printed circuit boards, referred to as printed boards, is one of the important components of the electronics industry. Almost every electronic device, from electronic watches and calculators to computers, communication electronics, military weapon systems, as long as there are electronic components such as integrated circuits, in order to electrically interconnect them, use printed boards. . In the larger electronic product research process, the most basic success factor is the design, documentation and manufacturing of the printed board of the product. The quality of printed board design and manufacturing directly affects the quality and cost of the entire product, and even leads to the success of commercial competition.

After the electronic equipment adopts the Printed Circuit Board, due to the consistency of the same Printed Circuit Board, the manual wiring is avoided, and the electronic components can be automatically inserted or mounted, automatically soldered, and automatically detected to ensure the quality of the electronic equipment. Increase labor productivity, reduce costs, and facilitate maintenance.


Printed Circuit Boards have evolved from single layer PCB(also Single Side PCB) to double-sided PCB, multi-layer PCB and flexible PCB(FPC), and still maintain their respective trends. Due to the continuous development of high precision, high density and high reliability, the volume is reduced, the cost is reduced, and the performance is improved, so that the Printed Circuit Board (PCB) still maintains a strong vitality in the development of electronic equipment in the future.


The domestic and international discussion on the future development trend of Printed Circuit Board manufacturing technology is basically the same, that is, high density, high precision, fine aperture, fine wire, fine pitch, high reliability, multi-layer, high-speed transmission, light weight, The development of thin-type PCB direction, at the same time, to improve PCB productivity, reduce PCB costs, reduce pollution, and adapt to the development of multi-variety and small-scale PCB production. The technical development level of Printed Circuits Board is generally represented by the line width, aperture, and plate thickness/aperture ratio on the Printed Circuit Board.


The creator of the Printed Circuit Board was the Austrian Paul Eisler. In 1936, he first used a Printed Circuit Board on the radio. In 1943, Americans used the PCB technology for military radio. In 1948, the United States officially recognized the PCB invention for commercial use. Printed Circuit Boards have been widely used since the mid-1950s.


Prior to the advent of the PCB, the interconnection between the electronic components was done by direct connection of the wires. Today, Printed Circuit Boards exist only in laboratory applications; Printed Circuit Boards are definitely in an absolute control position in the electronics industry.
