    Abstract: Methods and apparatuses are disclosed for fabricating a printed circuit board (PCB) having electromagnetic interference (EMI) shielding and also having reduced volume over conventional frame-and-shield approaches. Some embodiments include fabricating the PCB by mounting an integrated circuit to the PCB, outlining an area corresponding to the integrated circuit with a number of grounded vias, selectively applying an insulating layer over the PCB such that at least one of the grounded vias are exposed, and selectively applying a conductive layer over the PCB such that the conductive layer covers at least a portion of the integrated circuit and such that the conductive layer is coupled to the at least one of the grounded vias that are exposed.
