1, PCB (Printed Circuit Board), the Chinese name for the printed circuit board, also known as the printed circuit board, is an important electronic component, is the electronic components of the support body, is the carrier of the electrical connection of electronic components. Because it is the use of electronic printing technology, so it is called "printed" circuit board.
2, PCB role:
Electronic equipment using printed circuit boards, due to the consistency of similar printed circuit boards, thus avoiding the error of manual wiring, and electronic components can be automatically inserted or mounted, automatic soldering, automatic detection, to ensure the quality of the electronic equipment, improve labor productivity, reduce costs, and easy maintenance.
Expanded Information:
PCB can be more and more widely used because it has many unique advantages, summarized as follows:
1, can be high-density. Over the decades, printed circuit boards can be high-density with integrated circuits to increase the degree of integration and mounting technology advances and development.
2. High reliability. Through a series of inspection, testing and aging tests can ensure that the PCB long-term (life, generally 20 years) and work reliably.
3, designability. PCB various performance (electrical, physical, chemical, mechanical, etc.) requirements, can be standardized through the design of standardization, specification, etc. to achieve the printed circuit board design, short time, high efficiency.
4, producible. The use of modern management, standardization, scale (volume), automation and other production to ensure product quality consistency.
5, testability. The establishment of a more complete test methods, test standards, a variety of test equipment and instruments to detect and identify PCB product qualification and service life.
6, can be assembled. PCB products not only facilitate the standardization of various components for assembly, but also automation, large-scale mass production. At the same time, PCB and a variety of components assembly parts can also be assembled to form larger parts, systems, until the whole machine.
7, maintainability. As PCB products and a variety of components assembly parts are standardized design and large-scale production, therefore, these parts are also standardized. Therefore, once the system fails, can be fast, convenient, flexible replacement, and quickly resume service system work. Of course, more examples can be given. Such as making the system miniaturized, lightweight, high-speed signal transmission, and so on.
