Function:
After the electronic equipment adopts the Circuit Motherboard PCB, due to the consistency of the same Circuit Motherboard PCB, the manual wiring is avoided, and the electronic components can be automatically inserted or mounted, automatically soldered, and automatically detected to ensure the quality of the electronic equipment. Increase labor productivity, reduce costs, and facilitate maintenance.
Features:
Can be high density. For decades, the high density of Circuit Motherboard PCB has grown with the increased integration of integrated circuits and advances in mounting technology.
High reliability. Through a series of inspections, tests and aging tests, the Circuit Motherboard PCB can be reliably operated for a long period of time.
Designability. For the various performances of Circuit Motherboard PCB (electrical, physical, chemical, mechanical, etc.), the design of printed boards can be realized through design standardization and standardization, with short time and high efficiency.
Productivity. With modern management, it can carry out standardization, scale (quantity), automation and other production to ensure product quality consistency.
Testability. Established relatively complete test methods, test standards, various test equipment and instruments to detect and identify PCB product qualification and service life.
Assemblyability. PCB products not only facilitate the standardized assembly of various components, but also can be automated, large-scale mass production. At the same time, the PCB and various component assembly components can be assembled to form larger components and systems up to the complete machine.
Maintainability. Since PCB products and various component assembly components are produced in a standardized design and scale, 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. Of course, you can say more about it. Such as miniaturization and weight reduction of the system, high-speed signal transmission, and the like.
