Claim:
1. A circuit board assembly, comprising: a first circuit board having a first plurality of electronic components attached to a major surface of the first circuit board and electrically interconnected by conductive traces with a first plurality of conductive pads defined on the major surface of the first circuit board; and a second circuit board having a second plurality of electronic components attached to a first major surface of the second circuit board and electrically interconnected to a second plurality of conductive pads defined on a second major surface of the second circuit board opposite the first major surface, wherein the first plurality of conductive pads are electrically and mechanically coupled to the second plurality of conductive pads, wherein a portion of the first plurality of electronic components are disposed within a cavity defined by the second major surface, and wherein the cavity is characterized as a channel in the second major surface extending from a first minor surface of the second circuit board to a second minor surface of the second circuit board.
