The reason why PCB can be used more and more widely is that it has many unique advantages, which are summarized as follows.

1. It can be high-density.

For decades, the high density of printed boards has been able to develop along 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 can work reliably for a long period of time (usually 20 years).

3. Designability.

For PCB performance (electrical, physical, chemical, mechanical, etc.) requirements, printed board design can be achieved through design standardization, standardization, etc., with short time and high efficiency.

4. Manufacturability.

With modern management, standardized, scaled (quantitative), automated and other production can be carried out to ensure product quality consistency.

5. Testability.

A relatively complete test method, test standard, various test equipment and instruments have been established to detect and appraise the eligibility and service life of PCB products.

6. Assemblability.

PCB products are not only convenient for standardized assembly of various components, but also for automated and large-scale mass production. At the same time, PCB and various component assembly parts can be assembled to form larger parts and systems, up to the complete machine.

7. Maintainability.

Since PCB products and various component assembly parts are designed and produced on a large scale, these parts are also standardized.
