  • Techniques for providing an EMI seal for a circuit board
    Patent number: 7433203
    Abstract: A circuit board includes a first circuit board section which is configured to support a set of light emitting diodes, a second circuit board section which is configured to support high-speed electronic circuitry, and a boundary section which defines an EMI boundary between the first circuit board section and the second circuit board section. The boundary section includes a set of outer surface elongated ground strips configured to form an EMI seal onto which a set of EMI shields is capable of mounting. In some arrangements, the set of outer surface elongated ground strips take the form of metallic bands (e.g., layers of copper). Such bands can be integrated into the circuit board itself (e.g., during PCB fabrication), or added onto one or more of the circuit board surfaces (e.g., after PCB fabrication).
