ABSTRACT:
A chassis for containing a circuit board and a method of mounting a circuit board to a chassis. The chassis includes: (1) an outer chassis portion having a conductive material and having a plurality of associated pairs of integral circuit board mounts and outer chassis apertures formed in a substantially planar wall thereof, the circuit board mounts protruding toward an interior of the outer chassis portion and (2) an inner chassis portion having a plurality of associated pairs of integral spring members and inner chassis apertures formed in a substantially planar wall thereof, the plurality of circuit board mounts registerable with the plurality of inner chassis apertures to allow the plurality of circuit board mounts to pass through the plurality of inner chassis apertures as the wall of the inner chassis portion is brought into proximity with the wall of the outer chassis portion, the wall of the inner chassis portion substantially occluding the outer chassis apertures and the wall of the outer chassis portion substantially occluding the inner chassis apertures to form an electromagnetic interference ("EMI") shield, the plurality of circuit board mounts and the plurality of spring members cooperable to mount a circuit board to the chassis and to provide a grounding path from the circuit board to the chassis for electrical currents associated with the circuit board.
