PCB can be widely used because it has many special advantages:

　　A: It can be high-density For many years, the high-density of printed boards has been able to develop correspondingly with the improvement of integrated circuit integration and the advancement of mounting technology.

　　B: High reliability Through a series of technical means such as inspection, testing and aging test, it can ensure that the PCB works reliably for a long time (usually 20 years).

　　C: The designability requirements for various properties of the PCB (electrical, physical, chemical, mechanical, etc.) can be achieved through design standardization and standardization. In this way, the design time is short and the efficiency is high.

　　D: Manufacturability PCB adopts modern management, which can realize standardization, scale (quantity) and automatic production, so as to ensure the consistency of product quality.

　　E: Testability has established a relatively complete test method and test standard. Various test equipment and instruments can be used to detect and appraise the eligibility and service life of PCB products.

f: Assemblability PCB products are not only convenient for standardized assembly of various components, but also for automated and large-scale mass production. The PCB and other various components are integrated as a whole, and larger components and systems can be formed until the entire machine.

g: Maintainability. As PCB products and various components are assembled in a standardized design and large-scale production, these components are also standardized. Once the system fails, it can be replaced quickly, conveniently and flexibly. Restore the work of the system.

　　H: PCB has other advantages, such as miniaturization, lighter weight, and high-speed signal transmission.
