CB can be used more and more widely because it has many unique advantages, roughly as follows:
High density possible Over the 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, the PCB can be guaranteed to work reliably for a long time (usually 20 years).
Designability 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.
Manufacturability PCB adopts modern management, which can realize standardization, scale (quantity) and automatic production, so as to ensure the consistency of product quality.
Testability A relatively complete test method and test standard have been established. Various test equipment and instruments can be used to detect and appraise the eligibility and service life of PCB products. 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 PCB products and various components are assembled with standardized design and large-scale production, these components are also standardized. Therefore, once the system fails, it can be replaced quickly, conveniently and flexibly to quickly restore the system to work.
PCB has some other advantages, such as miniaturization, light weight, and high-speed signal transmission.
