Concave Bulkhead for PCI Card EMI Contact Assurance

    What is proposed is that the rear bulkhead web be bowed in slightly toward the PCI card bracket thus allowing for full contact to be made at top, middle, and bottom between the PCI card bracket and the rear bulkhead web through the spring gasket that is in between. The invention allows or ensures that contact will be made all up and down the web through the spring gasket to the PCI Card bracket thus grounding the PCI card as was the intention of the spring gasket. The problem as shown in the following figure is that the traditional method of manufacturing a straight formed bulkhead will bow out and away from the PCI card bracket and thus loose contact at the middle of the connection;

However by bowing the bulkhead in toward the PCI bracket a normally straight wall is achieved after contact of the PCI card bracket with the bulkhead;
