Peek inside the PCB Transmission Line eBook


What are PCB transmission lines?

A PCB transmission line is a type of interconnection used for moving signals from their transmitters to their receivers on a printed circuit board. It is composed of two conductors: a signal trace and a return path, which is usually a ground plane. The volume between the two conductors is made up of the PCB dielectric material.

Why are PCB transmission lines important?

It is crucial not to ignore the transmission line effects in order to avoid signal reflections, crosstalk, electromagnetic noise and other issues which could severely impact the signal quality of your board and cause errors.
