(Router Advanced Wiring Tips When designing a high-speed signal PCB or a messy PCB, it is often necessary to consider the problem of signal interference and anti-interference, that is, when planning such a PCB, it is necessary to improve the electromagnetic compatibility of the PCB. In order to end this intention, in addition to adding anti-annoying components in the schematic scheme, it is also necessary to consider this problem when planning the PCB, and one of the most important termination methods is to use the underlying know-how of high-speed signal routing)
