ABSTRACT:
A shield frame (800) is provided that allows for narrow width tracks to be used in a radio frequency (RF) shielding apparatus (900). The shield frame (800) is formed of a sheet metal frame (700) overmolded with a conductive elastomer (802) to form narrow edges (808, 810) that provide compliance in a +/−z-axis (814) directions while thicker portions of the overmolded conductive elastomer prevent buckling of the elastomer. The shield frame (800) can be sandwiched between two substrates (902, 908) of a communication device (900) having components (904) requiring RF shielding. Narrowing of the conductive elastomer overmold (802) allows ground tracks/runners (906) to be used on a substrate (902) which are narrower in width (912) than the shield frame width (702) thereby providing increased area for component placement.
