PCB knowledge: Characteristics of PCB
PCB has been more and more widely used, because it has many unique advantages. It can be summarized as follows.
a) Can be high density. For decades, PCB with high density can be developed with the integration of integrated circuits and surface mount technology progress.
b) High reliability. Through a series of inspection, testing and aging tests can ensure long time (use period, generally 20 years) and reliable work.
c) Designability. Various performance (electrical, physical, chemical, mechanical, etc.) requirements on PCB can be achieved by design standardization and standardization, etc. short time and high efficiency.
d) Productibility. The use of modern management, it can be produced by standardization production, scale production (mass production), automatic production etc to ensure product quality consistency.
e) Testability. Established a series of complete testing methods, testing standards, a variety of testing equipment and instrument etc, It can detect and identify the PCB quality and service life.
f) Can be assembled. PCB products not only facilitate the standardized assembly of various components, but also can be automated, large-scale mass produced. At the same time, PCB and its assembled components can be also assembled to form a larger component, system, until the whole machine.
g) Maintainability. As PCB products and various components of the assembly are standardized design and large-scale production, and thus, these assembled components are standardized.
So once the system fails, it can be fast, convenient and flexible replaced, quickly restore the service system.
