Abstract: A power supply enclosure device and method for suppressing the radiation of EMI from a power supply along power lines and for suppressing the entry of RF EMI into the power supply through the use of multiple tuned waveguides.

Abstract: A surrogate card assembly is configured to mimic the profile of a printed circuit board. The surrogate card assembly takes the place of a printed circuit board in an array of boards in a chassis or housing and mimics the active printed circuit boards with respect to directing air flow and providing EMC shielding.

Abstract: A flexible slotting system in a chassis easily accommodates printed circuit board assemblies having varying widths. A rib assembly is removably attached to the chassis frame to yield slots of the desired width. EMC gaskets over the entire length of the rib to prevent electromagnetic energy from leaking from the chassis.

Abstract: A chassis divides vertically, with front and rear sections of the chassis joined immediately adjacent a midplane printed circuit board that supports interconnectivity of electronic circuits. Wiring within the chassis is eliminated through directed connections of all components to the midplane. Minimal hardware is required for securing the front and rear sections together, and therefore accessing the midplane for assembly and service is convenient. All components except the midplane are installed and removed from either the front or rear of the chassis without opening or disassembling the chassis. The chassis layout and features facilitate effective cooling of the components in the chassis.
