Characteristics of printed circuit boards

PCB is increasingly widely used because it has many unique advantages, as follows:
High density
For many years, the high density of printed circuit boards has been able to develop accordingly with the improvement of integrated circuit integration and the advancement of installation 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
The requirements for various properties of PCB (electrical, physical, chemical, mechanical, etc.) can be achieved through design standardization and normalization. This way, the design time is short and the efficiency is high.
Manufacturability
PCB adopts modern management to achieve standardized, scaled (quantified) and automated production, thereby ensuring 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.
Assemblyability
PCB products are convenient for standardized assembly of various components, and can also be automated and mass-produced. In addition, assembling PCB with various other components as a whole 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 mass-produced, these components are also standardized. Therefore, once the system fails, it can be replaced quickly, conveniently and flexibly to quickly restore the system to work.
PCB has other advantages, such as making the system smaller and lighter, and increasing the speed of signal transmission.
