In high-frequency PCBs, power supply noise stands out as a significant form of interference. This article conducts a comprehensive analysis of the characteristics and origins of power supply noise in high-frequency PCBs, and offers practical and effective solu...

In the design of modern electronic devices, PCBs play a crucial role. The performance of PCBs directly affects the stability, reliability and transmission efficiency of the entire electronic system.

The PCB via is usually designed as through-holes (from the top surface to the bottom layer). When the PCB line connecting the via is routed closer to the top layer, a “stub”bifurcation will occur at the via of the PCB interconnect link
