PCB is used more and more widely because it has many unique advantages, generally as follows.
1.It can be densified.For decades, the high density of PCB developed with the improvement of IC integration and installation technology.
2.High reliability.A series of checks, tests, and aging tests ensures that the PCB will work reliably for a long period of time (generally 20 years).
3.Designability.PCB performance requirements (electrical, physical, chemical, mechanical, etc.) can be standardized by design, standardization, etc. to achieve the PCB design, short time, high efficiency.
4.Productive.Adopting modern management, can carry out standardization, scale (quantity) change, automation and so on production, guarantee product quality consistency.
5.Testability.A complete test method, test standard, various test equipment and instruments are established to test and evaluate the PCB product qualification and service life.
6.Assemblability.PCB products not only facilitate the standardized assembly of various components, but also can be automated and mass production.At the same time, PCB and various components can be assembled into larger parts, systems and even the whole machine.
7.Maintainability.As PCB products and various component assembly components are standardized design and mass production, these parts are also standardized.
Therefore, in case of system failure, the system can be replaced quickly, conveniently and flexibly, and the system can be quickly restored.
Of course, there are more examples.Such as making the system small, lightweight, signal transmission high - speed.
