    • 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.
    • 提供了一种屏蔽框架(800),其允许在射频(RF)屏蔽装置(900)中使用窄宽度的轨道。 屏蔽框架(800)由金属板框架(700)形成,该金属框架(700)用导电弹性体(802)包覆成型,以形成窄边缘(808,810),其沿+/- z轴(814)方向提供柔性,同时较厚 包覆成型的导电弹性体的一部分防止弹性体的翘曲。 屏蔽框架(800)可以夹在需要RF屏蔽的组件(904)的通信设备(900)的两个基板(902,908)之间。 导电弹性体包覆模制(802)的缩窄允许在比屏蔽框架宽度(702)宽的窄(912)的基底(902)上使用接地轨道/跑道(906),由此为组件放置提供增加的面积。
