What Are The Functions And Advantages Of PCB?
PCB is the abbreviation of Printed Circuit Board. The so-called printed circuit board refers to an assembly board that selectively processes mounting holes, connects the wires and assembles soldered electronic components on the insulating substrate, in order to achieve electrical connection between the components.
The emergence and development of printed circuit boards have brought major reforms to the electronics industry and greatly promoted the replacement of electronic products. This is because the printed circuit board PCB has many unique functions and advantages, summarized as follows:
1. Through the repeatability (reproducibility) and consistency of the graphics, errors in wiring and assembly are reduced, and the time for equipment maintenance, debugging and inspection is saved;
2. The design can be standardized to facilitate interchange;
3. High wiring density, small size and light weight, which is conducive to the miniaturization of electronic equipment;
4. It is conducive to mechanized and automated production, which improves labor productivity and reduces the cost of electronic equipment.
The manufacturing methods of printed boards can be divided into two categories: subtractive method (subtractive method) and additive method (additive method).
At present, the large-scale industrial production is still dominated by the corrosion copper foil method in the subtraction method.
5. Especially the bending resistance and precision of FPC flexible board make it can be better applied to high-precision instruments such as camera, mobile phone, video camera, etc.
