Application of characteristic impedance：
1. Applied to high-speed signal transmission and Automotive PCB high-frequency circuit, the electrical performance provided by the printed board must be able to prevent reflection during signal transmission, keep the signal intact, reduce transmission loss, and play a matching role. Complete, reliable, accurate, worry-free, and noise-free transmission of signals.

2. The size of impedance cannot be simply understood as the bigger the better or the smaller the better, the key is matching.
Control parameters of characteristic impedance
The dielectric constant of the sheet, the thickness of the dielectric layer, the line width, the copper thickness, and the thickness of the solder mask.
