Features of PCB

2020-03-21

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

High density

For many years, the high density of printed boards has been able to develop correspondingly with the increase in integrated circuit integration and advances in mounting technology.
High reliability
Through a series of inspection, testing and aging tests, it can ensure that the PCB works reliably for a long time (usually 20 years).
Designability
The requirements for various performances (electrical, physical, chemical, mechanical, etc.) of the PCB can be achieved through design standardization and standardization. The design time is short and the efficiency is high.
Producibility
PCB adopts modern management, which can realize standardization, scale (quantity), and automated production, thereby ensuring the consistency of product quality.
Testability
Established relatively complete test methods and test standards, which can be used to test and identify the qualification and service life of PCB products through various test equipment and instruments.
Assemblability
PCB products are not only convenient for standardized assembly of various components, but also for automated, large-scale mass production. In addition, the PCB and other various components are integrated to form larger components and systems, up to the entire machine.
Maintainability
Since the components of the PCB product and various components are assembled as a whole with standardized design and large-scale production, these components are also standardized. Therefore, once the system fails, it can be replaced quickly, easily and flexibly, and the system work can be quickly restored.
PCB also has some other advantages, such as miniaturizing and lightening the system, and speeding up signal transmission.
