The reason why PCB can be used more and more widely is because it has many unique advantages, which are roughly as follows:

High density possible

Over the years, the high density of printed boards has been able to develop correspondingly with the improvement of integrated circuit integration and the advancement of mounting technology.

High reliability

Through a series of technical means such as inspection, testing and aging tests, the PCB can be guaranteed to work reliably for a long time (usually 20 years).

designability

Requirements for various properties of PCB (electrical, physical, chemical, mechanical, etc.) can be achieved through design standardization, normalization, etc. In this way, the design time is short and the efficiency is high.

producibility

PCB adopts modern management, which can realize standardization, scale (quantization) and automatic production, so as to ensure the consistency of product quality.

Testability

A relatively complete test method and test standard have been established, and the qualification and service life of PCB products can be detected and identified through various test equipment and instruments.

assemblability

PCB products not only facilitate the standardized assembly of various components, but also enable automated and large-scale mass production. In addition, the overall assembly of the PCB and various other components can also form larger components, systems, and even complete machines.

maintainability

Since the components of PCB products and various components are assembled in a standardized design and large-scale production, these components are also standardized. Therefore, once the system fails, it can be replaced quickly, conveniently and flexibly, and the work of the system can be quickly restored.

PCB also has some other advantages, such as making the system smaller and lighter, and speeding up signal transmission.
