  • Low impedance connection for an EMI containment shield including metal plating bonded to the shielded equipment through openings in a conductive ribbon
    Patent number: 5965842
    Abstract: The present invention provides an EMI shield having a low impedance connection to ground for use in electronic equipment, particularly computer systems. More particularly, an EMI shield for electronic equipment is disclosed which includes a conductive ribbon, such as a copper ribbon with a polyimide backing, the conductive ribbon having openings and coupled to a ground plane. The conductive ribbon contacts a surface of a section of the electronic equipment to be shielded. A hold down frame of a non-conductive material holds the conductive ribbon in a fixed position on the section of the electronic equipment to be shielded. A metal plating, such as a combination of copper and nickel, bonds to the section of the electronic equipment to be shielded and to the conductive ribbon. The metal plating contains the EMI.
