Abstract:
A circuit board assembly of an information handling system has stepped diameter vias that carry communication signals through printed circuit board (PCB) substrates. Each stepped diameter via has a first barrel portion of a first diameter that is drilled through a first portion of the PCB substrates and that is at least lined with a conductive material to electrically conduct a selected one of: (i) a direct current and (ii) a communication signal from an outer layer to an internal layer of the more than one PCB substrate. Each stepped diameter via further includes a second barrel portion that extends from the first barrel portion deeper into the PCB substrates. The second barrel portion has a second diameter that is less than the first diameter and the smaller second diameter improves signal integrity (SI).

Claim (Index 12):
The IHS of  claim 7 , further comprising a third barrel portion aligned and on an opposite end the second barrel portion than the first barrel portion, the third barrel portion having a third diameter that is less than the second diameter to improve SI, the third barrel portion with the third diameter providing greater spacing from conductors for greater capacitance, thus enabling higher resonance frequency, wherein a number of via steps and diameters selected for each barrel portion are based on a stack-up thickness of the PCB, material of the PCB, and desired frequency of operation.
