Abstract:
1. An electronic device, comprising: a main printed circuit board (PCB) having a top surface, a bottom surface, and a cavity formed in the top surface extending toward the bottom surface but not through the main PCB, wherein one or more surfaces defining the cavity serve as a first RF shield; and a module PCB having at least one electrical component mounted on a top surface of the module PCB and at least one circuit component mounted on a bottom surface of the module PCB, wherein the module PCB is inverted and assembled adjacent the main PCB such that the top surface of the module PCB faces the uppermost top surface of the main PCB, and the at least one electrical component mounted on the top surface of the module PCB extends into the cavity; wherein the at least one circuit component mounted on the bottom surface of the module PCB comprises radio frequency (RF) circuitry; and wherein the module PCB includes a further RF shield, the further RF shield comprising an RF shield can covering the RF circuitry.
