The reason why PCB high-frequency circuit boards can be used more and more widely is because it has many unique advantages, which are summarized as follows:
1. Can be high-density. For decades, the high density of printed boards has been able to develop with the improvement of integrated circuit integration and the advancement of mounting technology.
2. High reliability. Through a series of inspections, tests and aging tests, the PCB high-frequency circuit board can be guaranteed to work reliably for a long time (use period, generally 20 years).
3. Designability. For various performance (electrical, physical, chemical, mechanical, etc.) requirements of PCB high-frequency circuit boards, printed board design can be realized through design standardization, standardization, etc., with short time and high efficiency.
4. Manufacturability. With modern management, standardization, scale (quantity), automation and other production can be carried out to ensure the consistency of product quality.
5. Testability. A relatively complete test method, test standard, various test equipment and instruments have been established to detect and identify the qualification and service life of PCB high-frequency circuit board products.
6. Assemblability. PCB high-frequency circuit board products are not only convenient for standardized assembly of various components, but also automatic and large-scale mass production. At the same time, PCB high-frequency circuit boards and various component assembly parts can also be assembled to form larger components, systems, and even complete machines.
7. Maintainability. Since PCB high-frequency circuit board products and various component assembly parts are designed and produced in a standardized manner, these parts 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, more examples can be given. Such as making the system miniaturized, lightweight signal transmission high-speed and so on.
