Trace Resistance vs Trace Impedance

When Trace Resistance Trumps Trace Impedance Trace resistance, trace impedance, plane resistance, and plane impedace: when do you need to worry about all of these quantities? Resistance and impedance both are important in small traces and fat rails on a PCB, both internally and externally. Sometimes a new designer entering the world of impedance controlled buses might think they have a trace resistance target, when really they have a trace impedance target. While in power electronics, we Read Article
