Characteristic Impedance Characteristic Impedance (Z0) is an important parameter in transmission line theory, reflecting the impedance that transmission lines present to the propagation of electromagnetic waves. The characteristic impedance of PCB traces is related to the trace width, spacing, thickness, dielectric thickness, and dielectric constant. Since space can also be considered a type of medium, … Read more
Core Content Overview: This patent discloses a printed circuit board, power receiving module, battery unit, and power receiving communication module. The core innovation lies in optimizing the layout and connection methods of coils between different layers of the printed circuit board, particularly by introducing a design that incorporates vias in the crossover areas to reduce … Read more
Introduction:Everyone knows that impedance should be continuous. However, as Luo Yonghao said, “In life, there are always times when you step in something unpleasant,” PCB design also has its moments of impedance discontinuity. What should we do? Characteristic Impedance Characteristic Impedance: Also known as “Feature Impedance”, it is not a DC resistance, but a concept … Read more
