1.Definition of ground What is ground? The definition of ground that everyone learns in textbooks is: ground is an equipotential body that serves as the potential reference point of the circuit. This definition does not conform to the actual situation. The potential on the actual ground is not constant. If you use an instrument to…

As frequencies continue to increase, controlling the phase consistency of PCB materials becomes increasingly difficult. Accurately predicting the phase change of PCB materials is not a simple or routine task. The signal phase of high-frequency and high-speed PCBs depends largely on the structure of the transmission lines made from them, as well as the dielectric…
