PCB Is The Supporting Body Of Electronic Components Sep 11, 2017


PCB is printed Circuit Board PCB

PCB is the electronic product of the circuit components and components of the supporting parts. It provides electrical connections between circuit elements and devices. With the rapid development of electronic technology, the density of PCB has become more and more high. PCB design has great impact on anti-jamming ability. Practice has proved that even if the circuit schematic design is correct, printed circuit board design is improper, PCB also will have a negative impact on the reliability of electronic products. PCB, also known as printed circuit boards, printed circuit boards, abbreviated to printed boards, the English abbreviation for the PCB (printed circuit board) or PWB (printed wiring board), the insulating plate as the base, cut into a certain size, with at least one conductive graphic, PCB And the cloth has the hole (such as the component hole, the fastening hole, the metal hole and so on), uses in replaces the former installment electronic component's chassis, and realizes the electronic component connection mutually. Because this kind of board is made by electronic printing, it is called "printed" circuit board. PCB The customary "printed circuit board" is "printed circuits" is not accurate, because there is no "printed element" on the PCB and only wiring. It is an important electronic component, is the support of electronic components.

PCB is more and more widely used, because it has a lot of unique advantages, trichosanthes as follows: can be high-density. For decades, the high density of PCB has been developed with the improvement of integrated circuit integration and installation technology. High reliability. PCB Through a series of inspection, testing and aging tests can ensure that the PCB long-term (use, generally for 20) and reliable work. can be designed. PCB Performance (electrical, physical, chemical, mechanical, etc.) requirements, can be designed through standardization, standardization, etc. to achieve PCB design, short time, high efficiency. can be productive. PCB The use of modern management, can be standardized, scale (volume), automation and other production, to ensure consistency of product quality. Testability. Set up a relatively complete test methods, testing standards, a variety of testing equipment and instruments to detect and identify the PCB product eligibility and service life. can be assembled. PCB products are not only convenient for a variety of components standardized assembly, and can be automated, large-scale production. At the same time, PCB and various components assembly parts can also be assembled to form larger parts, systems, until the machine. Maintainability。 As PCB products and components are assembled in a standardized design and large-scale production, and therefore, PCB these components are also standardized. Therefore, once the system fails, can quickly, easily, flexibly to replace, quickly restore service system work. Of course, there are more examples. such as the miniaturization of the system, lightweight, high-speed signal transmission and so on.
