First, let's start with a few things to know about signal integrity and via stubs. A via stub is the part of a via which is not used for signal transmission. In the example depicted below, part A of the via is used for signal propagation from the conductor C1 on an outer layer to the conductor Cn on an inner layer. But part B of the via is extraneous – thus, the via stub in this case.
