Abstract:

In a mounting system for an assembly in a high-frequency desktop device, a chassis element ("element") provides ground. For best ground, features formed in the element near a first edge of the assembly force the two together with no fastener there. Fasteners or other provisions secure the assembly, near its second edge, to the element. The features capture the first edge at installation; the fasteners etc. secure the assembly, near its second edge so that the features pinch the first. In another form of the system (1) first raised shapes formed in the element support the assembly near its first edge; (2) features, also formed in the element next to the first shapes, engage and capture the first edge; (3) second raised shapes, formed in the element, support the assembly near its second edge; and (4) fasteners etc. secure the assembly, near its second edge. Preferably the features are so spaced above the first raised shapes as to slightly flex the assembly; no separate fastener holds the assembly to the element near the first raised shapes; the first or second shapes, or both, are metallic and engage grounding pads; and the element is formed metal, structurally integrated with other chassis and case pieces.
