PCB can be applied more and more widely because it has many unique advantages, as outlined below.
Density can be increased. For decades, the high density of PCBs has grown as integrated circuits have become more integrated and installation technology has advanced.
High reliability. Through a series of inspections, tests, and aging tests, the PCB can be reliably operated for a long period of time (usually 20 years).
Designability. For PCB performance (electrical, physical, chemical, mechanical, etc.) requirements, PCB design can be achieved through design standardization, standardization, etc., with short time and high efficiency.
Productivity. With modern management, we can conduct standardization, scale (quantity), automation and other production, and ensure the consistency of product quality.
Testability. Established a relatively complete test method, test standards, a variety of test equipment and instruments to detect and identify the qualification and service life of PCB products.
Assemblability. PCB products not only facilitate the standard assembly of various components, but also can be automated, large-scale mass production. At the same time, PCBs and various component assembly parts can also be assembled to form larger parts and systems up to the complete machine.
Maintainability. Since PCB products and various component assembly parts are produced with standardized design and scale, these components are also standardized. Therefore, once the system fails, it can be quickly, easily, and flexibly replaced, quickly recovering the system. Of course, you can also give more examples. For example, the system is miniaturized, lightweight, and the signal transmission speed is increased.
