PCB board classification, do you understand?

PCB board is the load body of all electronic products, that is, electronic products must form a complete circuit through PCB board to realize various functional requirements.

So why should PCB boards be classified and what is the purpose of classification?

PCB board can be high-density. For decades, the high density of printed boards has developed with the improvement of integrated circuit integration and the progress of installation technology.
PCB board has high reliability. Through a series of inspections, tests and aging tests, it can ensure the long-term (service life, generally 20 years) and reliable operation of PCB.
PCB board designability. For various performance (electrical, physical, chemical, mechanical, etc.) requirements of PCB, PCB design can be realized through design standardization and standardization, with short time and high efficiency.
PCB board producibility. With modern management, standardized, large-scale (Quantitative) and automatic production can be carried out to ensure the consistency of product quality.
PCB testability. A relatively complete test method, test standard, various test equipment and instruments are established to detect and identify the qualification and service life of PCB products.
PCB assembly. PCB products are not only convenient for standardized assembly of various components, but also for automatic and large-scale mass production. At the same time, the PCB board and various component assembly parts can also be assembled to form larger parts and systems until the whole machine.
PCB maintainability. Because PCB products and various component assembly parts are based on standardized design and large-scale production, these parts are also standardized. Therefore, once the system fails, it can be replaced quickly, conveniently and flexibly to quickly restore the system. Of course, more examples can be given. Such as miniaturization and lightweight of the system, high-speed signal transmission, etc.
