PCB, or printed circuit board, is the cornerstone of the modern electronics industry. Its design technology directly affects the performance, reliability and production efficiency of electronic equipment. With the continuous development of science and technology, PCB design technology is also improving, from a simple single-layer board to a complex multi-layer board, from the traditional wiring method to the modern automatic wiring technology, each step reflects the crystallization of human wisdom.

PCB design technology is exquisite or not, directly related to the quality and stability of electronic equipment. Excellent PCB design can reduce electromagnetic interference, improve signal transmission efficiency, thereby improving the overall performance of the device. At the same time, reasonable PCB design can also reduce production costs, improve production efficiency, and create greater economic benefits for enterprises.
