Abstract

An improved RF shielding apparatus includes a shield frame having a nonconductive gasket mounted to the edges thereof. A conductive layer is deposited on the gasket and shield frame such that a substantially continuous layer surrounds the gasket and shield frame.

Claims

1. An RF shield, comprising:

a shield frame for covering electronic components to be shielded, the shield frame including a plurality of guideposts along edges thereof;

an elastic band gasket placed around the plurality of guideposts such that the gasket rests along the edges of the shield frame; and

a conductive layer covering a predetermined portion of surfaces of the shield frame and gasket.

2. The RF shield of claim 1, wherein the gasket comprises a conductive gasket.

3. The RF shield of claim 1, wherein the gasket comprises a nonconductive gasket.

4. The RF shield of claim 1 wherein the conductive layer comprises aluminum.

5. The RF shield of claim 1 wherein the conductive layer comprises a conductive paint.

6. The RF shield of claim 3 wherein the nonconductive gasket comprises a rubber gasket.
