Unique advantages of PCB:
① High density is possible. For decades, the high density of printed boards has been able to develop along with the improvement of integrated circuit integration and the advancement of mounting technology.
② High reliability. Through a series of inspections, tests and aging tests, the PCB can be guaranteed to work reliably for a long time (use period, generally 20 years).
③ can be designed. For PCB performance (electrical, physical, chemical, mechanical, etc.) requirements, printed board design can be achieved through design standardization, standardization, etc., with short time and high efficiency.
④ Producibility. With modern management, it can be standardized, scaled (quantified), automated, etc., to ensure product quality consistency.
⑤ Testability. A relatively complete test method, test standard, various test equipment and instruments have been established to detect and appraise the eligibility and service life of PCB products.
⑥ Assemblability. PCB products are not only convenient for standardized assembly of various components, but also for automated and large-scale mass production. At the same time, PCB and various component assembly parts can be assembled to form larger parts, systems, and complete machines.
⑦ Maintainability. Since PCB products and various component assembly parts are designed and produced on a large scale, these parts are also standardized. Therefore, once the system fails, it can be replaced quickly, conveniently and flexibly, and the system can be restored quickly. Of course, there can be more examples. Such as miniaturization and weight reduction of the system, and high-speed signal transmission.
