Understanding Impedance in PCBs Impedance is a measure of the opposition that a circuit presents to the flow of alternating current (AC) at a given frequency. In the context of PCBs, impedance refers to the characteristic impedance of the transmission lines, which are the conductive traces that carry signals between components. The characteristic impedance of…
