PCB



PCB (Printed Circuit Board), the Chinese name for the printed circuit board, referred to as the PCB, is one of the important components of the electronics industry.

Almost every type of electronic device, small electronic watches, calculators, large computers, communications electronics, military weapons systems, as long as there are integrated circuits and other electronic components, for the electrical interconnection between them, we must use the printed circuit board .

In the larger electronics research process, the most fundamental success factor was the design, documentation, and manufacture of the product's printed circuit board. Printed board design and manufacturing quality directly affects the quality and cost of the entire product, and even lead to commercial success or failure.


PCB function:

Electronic devices using PCB, due to the consistency of similar PCB, thereby avoiding the error of the manual wiring, and can achieve automatic insertion or placement of electronic components, automatic solder, automatic detection, to ensure the quality of electronic equipment , Increased labor productivity, reduced costs and ease of maintenance.
