    Abstract: Manufacturing circuits with reference plane voids over vias with a strip segment interconnect permits routing critical signal paths over vias, while increasing via insertion capacitance only slightly. The transmission line reference plane defines voids above (or below) signal-bearing plated-through holes (PTHs) that pass through a rigid substrate core, so that the signals are not degraded by an impedance mismatch that would otherwise be caused by shunt capacitance from the top (or bottom) of the signal-bearing PTHs to the transmission line reference plane. In order to provide increased routing density, signal paths are routed over the voids, but disruption of the signal paths by the voids is prevented by including a conductive strip through the voids that reduces the coupling to the signal-bearing PTHs and maintains the impedance of the signal path conductor.

    Abstract: An apparatus is provided that comprises a plurality of signaling planes providing signal pathways and at least one internal reference plane providing either a voltage or a ground connection. The at least one internal reference plane are provided between at least two of the signaling planes. The apparatus further comprises a signal blind/buried via coupling a signal pathway of a first one of the at least two signaling planes with a signal pathway of a second one of the at least two signaling planes. The blind/buried via runs through the at least one internal reference plane. The apparatus also comprises at least one first conductive feature in the first one of the at least two signaling planes. The at least one first conductive feature is in close proximity to the signal blind/buried via and increases the capacitive coupling of currents in the reference planes of the apparatus.
