PCB, also known as printed circuit board, is an important electronic component, a support body for electronic components, and a carrier for their electrical interconnection. It is called a “printed” circuit board because of the electronic printing technology it uses.
PCB Introduction
PCB (printed circuit board) that is, printed circuit board, referred to as printed circuit board, is one of the important components of the electronics industry. Almost every kind of electronic equipment, from small to electronic watches, calculators, large to computers, communication electronics, military weapons systems, as long as there are integrated circuits and other electronic components, in order to make the electrical interconnection between the various components, are to use the printed circuit board. Printed circuit board by the insulating base board, connecting wires and assembly welding electronic components of the pads, with conductive lines and insulating base board of the dual role.
It can replace the complex wiring to achieve 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 reducing the labor intensity of workers; and reduce the size of the machine, reduce product costs, improve the quality and reliability of electronic equipment.
Printed wiring board has good product consistency, it can adopt standardized design, which is conducive to mechanization and automation in the production process. At the same time, the whole piece of printed wiring board after assembly and debugging can be used as an independent spare part, which is convenient for the interchangeability and maintenance of the whole product. At present, the printed wiring board has been extremely widely used in the manufacture of electronic products.
The first printed circuit boards used were paper-based copper-clad printed boards. Since the emergence of semiconductor transistors in the 1950s, the demand for printed boards has risen sharply.
In particular, the rapid development and widespread use of integrated circuits, so that the size of electronic equipment is getting smaller and smaller, circuit wiring density and increasing difficulty, which requires the printed board to be updated. At present, the variety of printed boards has developed from a single panel to double-sided, multilayer board and flexible board;
structure and quality has also developed to ultra-high density, miniaturization and high reliability degree; new design methods, design supplies and board materials, board 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 the specialized printed circuit board manufacturers, mechanization, automated production has completely replaced the manual operation.
Origin of pcb
The creator of the PCB was the Austrian Paul eisler ( Paul eisler), who first used printed circuit boards in radios in 1936. 1943, the Americans mostly used the technology in military radios, and in 1948, the United States officially recognized the invention for commercial use. Printed circuit boards have only been widely used since the mid-1950s. Printed circuit boards can be found in almost every type of electronic device.
PCB’s main function is to make a variety of electronic components to form a predetermined circuit connection, the role of relay transmission, is the key electronic interconnections of electronic products, “the mother of electronic products,” said.
