Abstract

An improved shielding assembly for a circuit board. The assembly includes a multi-layer circuit board, each layer of which has ground planes around the perimeter thereof. An edge plating on the circuit board connects the ground planes to one another. A number of tab holes are also in the board, and the shielding assembly is formed as a conductive box which is connected to the tab holes. A shielded area is formed within the shielding assembly. The shielding assembly is preferably formed by etching fold locations and folding, and by etching tabs to be formed.
