How to Calculate Trace Impedance to IPC-2141 Standard – ATM Quick Take | DigiKey

Trace impedance results when two or more conductor traces or conductive substrates react to each other via emerging electric fields (capacitive reactance) and the magnetic flux that develops around a trace as current passes through it (inductive reactance). This video explains how to use DigiKey’s Trace Inductance Calculator as a shortcut to manual calculations when evaluating PCB trace impedance.
