What is PCB and its advantages?
PCB (Printed Circuit Board), the Chinese name is printed circuit board, also known as printed circuit board. It is an important electronic component, a support for electronic components, and a carrier for the electrical connection of Electronic Components. Because it is made by electronic printing, it is called a "printed" circuit board. The printed circuit board is an assembly board for electrical connection between components by drilling mounting holes at predetermined positions and placing soldering pads for soldering electronic components and electronic connectors on the insulating substrate, so that the circuit board can achieve the expected design function .
The reason why PCB can be used more and more widely is that it has many unique advantages, which are summarized as follows.
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).
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.
PCBA Manufacturing: adopting modern management, can carry out standardization, scale (quantity), automation and other production, to ensure the consistency of product quality.
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.
Maintainability: As PCB products and various component assembly parts are standardized and produced on a large scale, these parts 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. Of course, there can be more examples. Such as miniaturization and weight reduction of the system, and high-speed signal transmission.
