In one embodiment, an integrated circuit package comprises a substrate
including a first surface having a plurality of signal land pads and a
second surface having a plurality of signal die pads; a plurality of
signal connectors arranged to electrically couple the plurality of the
signal land pads to the plurality of the signal die pads; and a ground
plane, disposed in an adjacent, spaced-apart relationship to the
plurality of signal land pads. The ground plane includes a plurality of
holes with at least one of the holes having at least one of the signal
connectors extending therethrough and being dimensioned and configured
approximately to be as large or larger than at least one of the signal
land pads disposed adjacent to the at least one hole.
