PCB characteristics – knowledge base

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

Can be high-density

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 inspections, tests and aging tests, and other technical means, the PCB can be guaranteed to work reliably for a long time (usually 20 years).


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


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


A relatively complete test method and test standard have been established. Various test equipment and instruments can be used to detect and appraise the eligibility and service life of PCB products.


PCB products are not only convenient for standardized assembly of various components, but also for automated and large-scale mass production. In addition, by assembling the PCB and various other components as a whole, larger parts and systems can be formed to the complete machine.


Since 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 system can be quickly restored to work.

PCB has other advantages, such as miniaturization and lightweight of the system, and high-speed signal transmission, etc.
