Patent ID: 7443693

Claim:
A shielded printed circuit board (PCB) comprising: a PCB comprising a first surface and a second surface; a metallized polymer shield coupled to the first surface of the PCB; a grounded layer coupled to the second surface of the PCB; a plurality of conductive vias that extend from the first surface to the grounded layer so as to electrically couple the metallized polymer shield to the grounded layer; an electronic component mounted to the first surface of the PCB; wherein adjacent conductive vias are spaced within the PCB a distance that is small enough to reduce a passage of electromagnetic radiation from the electronic component through the spacing between the adjacent conductive vias; wherein the metallized polymer shield comprises a shaped polymer substrate that provides a cavity that is sized and shaped to receive the electronic component, wherein the shaped polymer substrate comprises a flange that extends around at least a portion of a perimeter of the cavity in a direction that is substantially parallel to the first surface of the PCB; and a metal layer disposed over at least one surface of the shaped polymer substrate.
