PCB has been more and more widely used, because it has many unique advantages, are summarized as follows.
High density. For decades, the printed board density has been developing with the integration of integrated circuits and the progress of installation technology.
High reliability. Through a series of tests, tests and aging tests, PCB is guaranteed to work reliably for a long time (usually 20 years).
Design feasibility. For the various requirements of PCB (electrical, physical, chemical, mechanical, etc.), the design of printed boards can be realized through standardization and standardization. The time is short and the efficiency is high.
Productivity. Modern management can be standardized, scale (quantity), automation and other production, to ensure consistency of product quality.
Testability. Established a relatively complete testing methods, testing standards, a variety of testing equipment and instruments to detect and identify PCB product qualification and service life.
Assembly ability. PCB products are not only convenient for standardized assembly of various components, but also can be automated, large-scale and mass production. At the same time, PCB and components assembly components can be assembled to form larger parts and systems, until the whole machine.
Maintainability. These components are standardized as PCB products and components assembly components are standardized and scaled up. Therefore, once the system fails, it can be replaced quickly, conveniently and flexibly, and the system work can be quickly resumed. Of course, you can also give more examples. Such as miniaturization of the system, lightweight, high-speed signal transmission.
