    摘要: Apparatus is disclosed for shielding an electric circuit, mounted on a circuit board, from electromagnetic interference (EMI). The electrical circuit is mounted on one side of a circuit board. A conductive layer on the other side of the circuit board functions as a ground plane. An enclosure of insulating material is open on one side and has an inside surface of electrically conductive material. The circuit board and enclosure are joined together so that the electrical circuit on the circuit board is substantially completely surrounded by the electrically conductive material on the inside surface of the enclosure and by the ground plane of the circuit board. Thus, there is provided an effective EMI shield for the electrical circuit.
