Structure to Dampen Barrel Resonance of Unused Portion of Printed Circuit Board Via

摘要

A printed circuit board includes a first trace, a second trace, and a first via. The first trace is in a first conductive layer. The second trace is in a second conductive layer. The first via interconnects the first trace and the second trace, and communicates a first signal from the first trace to the second trace through a third conductive layer. The third conductive layer has a higher impedance than the first conductive layer and the second conductive layer.
