摘要： A light guide/shield assembly for use with a circuit board includes an upstanding, electrically conductive shield wall adapted to be mounted on and electrically grounded to the circuit board. The shield wall defines an opening. A light guide member including a light transmissive guide body and an electrically conductive shield layer is mounted on the shield wall such that the shield layer overlies the opening. The light guide/shield assembly thereby defines an RF shielded chamber. The light guide/shield assembly may further include an LCD panel mounted on the light guide member. An RF shielded PCB assembly includes a circuit board including an electrical ground and the light guide/shield assembly mounted thereon.

摘要： The present invention provides an improved keyboard for a cellular telephone or the like. The improved keyboard includes an additional shielding layer which is added to the keypad to prevent RF leakage in the direction of the user. The shielding layer includes an insulating layer and a conductive layer. The conductive layer may be added in one of two ways. First, a conductive layer made of nickel foil or other suitable material may be molded directly into the keypad. Second, the conductive layer may be plated or painted on the surface of the keypad. In any such process, a layer of insulating material is added to the bottom surface of the conductive layer to prevent shorts. Finally, doping of the keypad may be used to improve the effectiveness of the shielding by using it with either of the aforementioned methods of implementation.

摘要翻译： 本发明提供了一种用于蜂窝电话等的改进的键盘。 改进的键盘包括附加的屏蔽层，其被附加到键盘以防止在用户的方向上的RF泄漏。 屏蔽层包括绝缘层和导电层。 导电层可以以两种方式之一加入。 首先，可以将由镍箔或其它合适材料制成的导电层直接模制到键盘中。 第二，导电层可以被电镀或涂在键盘的表面上。 在任何这样的工艺中，将绝缘材料层加到导电层的底表面以防止短路。 最后，可以使用键盘的掺杂来通过使用上述实施方法中的任一种来提高屏蔽的有效性。
