It is the support body of electronic components, is the carrier of the electrical connection of electronic components.
PCB (Printed Circuit Board), the Chinese name for the printed circuit board, also known as printed circuit boards, is an important electronic component.
It is the support body of electronic components, is the carrier of the electrical connection of electronic components
PCB product type:
By the product structure is distinguished as: rigid boards, flexible boards, rigid-flexible combination of boards, the three major categories.
By the number of layers of the conductive path is divided into: single-sided board, double-sided board and multilayer board.
According to the new technology or structural characteristics, performance characteristics can be divided into: high-density interconnect (HDI) board / micro-conductor through-hole boards,
Metal-based (metal core) PCB, thick copper PCB, embedded components PCB, high-frequency PCB, backplane, IC packages, such as loading boards.
PCB has been extremely widely used in the production of electronic products in the manufacturing, because the PCB board has the following characteristics:
1, can be high-density. Over the past few decades, the high density of printed circuit boards can be improved with the integrated circuit integration and mounting technology advances and development.
2, high reliability. Through a series of inspection, testing and aging tests can ensure that the PCB long-term (life, generally 20 years) and work reliably.
3, designability. PCB various performance (electrical, physical, chemical, mechanical, etc.) requirements, can be standardized through the design of standardization, specification, etc. to achieve the printed circuit board design, short time, high efficiency.
4, producible. The use of modern management, standardization, scale (volume), automation and other production to ensure product quality consistency.
5, testability. The establishment of a more complete test methods, test standards, a variety of test equipment and instruments to detect and identify PCB product qualification and service life.
6, can be assembled. PCB products not only facilitate the standardization of various components for assembly, but also automation, large-scale mass production. At the same time, PCB and a variety of components assembly parts can also be assembled to form larger parts, systems, until the whole machine.
7, maintainability. As PCB products and a variety of components assembly parts are standardized design and large-scale production, and therefore, these parts are also standardized
Summary: we can see the electronic equipment are inseparable from it, electronic watches, calculators, general-purpose computers, computers, communication electronic equipment, military weapons systems, as long as there are integrated circuits and other electronic components. Widely used in major industries, communications, medical, industrial, automotive, lighting, aviation.
