The reason PCBS have become increasingly common is because they've got a lot of unique advantages, and they've all been mentioned as follows.
It can be densified.For decades, PCB high density has been developed with the improvement of integrated circuit integration and installation technology.
High reliability.Through a series of inspection, test and aging test, PCB can be guaranteed to work reliably in the long term (the service life is generally 20 years).
Designability.PCB various performance (electrical, physical, chemical, mechanical, etc.) requirements, through design standardization, standardization, etc. to achieve the PCB design, short time, high efficiency.
Productive. Modern management, standardization, scale (quantity), automation for production, ensure product quality consistency.
Testability.A relatively complete test method, test standard, various test equipment and instruments are established to detect and identify the PCB product eligibility and service life.
Assemblability. PCB products not only facilitate the standardized assembly of various components, but also can be automated, large-scale mass production.At the same time, PCB and various component assembly parts can be assembled to form larger parts, systems, and even the whole machine.
Maintainability.Because PCB products and various component assemblies are designed and manufactured on a standardized basis,so they are standardized. Therefore, in case of system failure, it can be replaced quickly, conveniently and flexibly to restore the system to work quickly.Of course, there are more advantages such as system miniaturization, lightweight, high-speed signal transmission and so on.
