    • Passive device assembly (202) for accurate ground plane control is disclosed. A passive device assembly includes a device substrate (214) conductively coupled to a ground plane separation control substrate (216). A passive device (204) disposed on a lower surface (220) of the device substrate is separated from an embedded ground plane (210) mounted on a lower surface of the ground plane separation control substrate by a separation distance (D1). The separation distance is accurately controlled to minimize undesirable interference that may occur to the passive device. The separation distance is provided inside the passive device assembly. Conductive mounting pads (212) are disposed on the lower surface of the ground plane separation control substrate to support accurate alignment of the passive device assembly on a circuit board. By providing sufficient separation distance inside the passive device assembly, the passive device assembly can be precisely mounted onto any circuit board regardless of specific design and layout of the circuit board.
    • 公开了用于精确地平面控制的无源装置组件(202)。 无源器件组件包括导电耦合到接地平面分离控制衬底(216)的器件衬底(214)。 布置在器件基板的下表面(220)上的无源器件(204)与安装在接地平面分离控制基板的下表面上的嵌入式接地平面(210)隔开分离距离(D1)。 精确控制分离距离以最小化无源设备可能发生的不希望的干扰。 分离距离设置在无源装置组件内部。 导电安装垫(212)设置在接地平面分离控制衬底的下表面上,以支持无源装置组件在电路板上的精确对准。 通过在无源器件组件内提供足够的分离距离,无源器件组件可以精确地安装到任何电路板上,而不管电路板的具体设计和布局。
