For decades, the high density of printing plate can be developed with the improvement of integrated circuit integration and installation technology.
Through a series of inspection, testing and aging tests, the rogers fr4 PCB can be guaranteed to work reliably for a long period of time (generally 20 years).
PCB's various performance (electrical, physical, chemical, mechanical, etc.) requirements can be standardized by design, standardization, etc. to achieve printing plate design, short time, high efficiency.
Productive. Adopt modern management, can carry on standardization, scale (quantity) change, automation to wait for production, assure product quality consistency.
A relatively complete test method, test standard, various test equipment and instruments have been established to test and verify the qualification and service life of high tg fr4 PCB products.
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 components can be assembled into larger components, systems, and even the whole machine.
As PCB products and components are manufactured in a standardized design and scale, these components are also standardized. Therefore, once the system fails, it can be replaced quickly, conveniently and flexibly, and the system can be quickly restored to work. Of course, there are more examples. Such as system miniaturization, lightweight, high - speed signal transmission.
