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.

　　High reliability

　　Through a series of inspections, tests and aging tests and other technical means, it can ensure that the PCB works reliably for a long time (usually 20 years).

　　 can be designed

　　 The requirements for various properties of 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.

　　Producibility

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

　　 testability

　　 has established relatively complete test methods and test standards, and can detect and appraise the eligibility and service life of PCB products through various test equipment and instruments.

　　Assemblability

　　PCB products are not only convenient for standardized assembly of various components, but also for automated and large-scale mass production. In addition, by assembling the PCB and various other components as a whole, larger parts and systems can be formed to the complete machine.

　　 maintainability

　　Since the parts assembled with PCB products and various components are manufactured in standardized design and large-scale production, these parts are also standardized. Therefore, once the system fails, it can be replaced quickly, conveniently and flexibly, and the system can be quickly restored to work.

　　PCB also has some other advantages, such as miniaturization and light weight of the system, and high-speed signal transmission.
