摘要:
An apparatus, system, and method provide electrostatic discharge (ESD) protection in electronic devices by guiding electrostatic charges to a ground through ESD channels within electrical insulation sheet. The ESD channels are positioned within the electrical insulation sheet to provide electrical paths to ground having a lower impedance than electrical paths to protected areas covered by the electrical insulation sheet. Accordingly, an ESD follows the path of least resistance safely to ground rather than to a critical component within the electronic device. In the exemplary embodiment, the ESD channels are openings in a dome contact layer of a keypad where the openings are positioned over one or more ground areas of a printed circuit board (PCB) and the insulting material of the dome contact layer covers areas of the PCB that are protected from ESD. By implementing dedicated GPIO lines, grounded metal domes cover the signal pads in the target discharge area to protected the GPIO lines from ESD. Device components are protected from ESD without additional ports or insulation.

a chassis assembly that reduces the amount of electromagnetic radiation entering or leaving the interior of the chassis assembly. The chassis assembly includes a chassis cover and chassis back. The chassis cover includes a plurality of dimpled spring contacts and hemmed edges and hemmed lips. The chassis back includes a chassis back top portion adapted to mate with the chassis cover, such that the chassis back top portion is in good contact with the one or more dimpled spring contacts, providing good electrical conductivity. Further, the chassis assembly is designed such that the mating between the chassis cover and chassis back provides a tortuous path to any electromagnetic radiation disposed to enter or leave the chassis assembly.

A method of manufacturing a chassis assembly to reduce electromagnetic interference is disclosed. The method includes forming a chassis having a chassis cover top portion, a chassis cover step portion, a chassis cover pre-step portion, a hemmed edge, a hemmed lip, and one or more dimpled spring fingers, by forming a first bend at the hemmed edge residing between the hemmed lip and the chassis cover pre-step portion, forming a second bend between the chassis cover step portion and the chassis cover pre-step portion, and forming a third bend between the chassis cover top portion and the chassis cover step portion. The method further including forming a fourth bends between a chassis back top portion and a chassis back. The formed chassis cover is then seated with the chassis back to create a tortuous path.

A patch antenna includes a radiating element positioned on one side of a printed circuit board and an electromagnetic shield positioned on the opposite side of the printed circuit board. The electromagnetic shield forms at least a portion of a counterpoise and is connected to the ground of the PCB in at least one location. Design flexibility in positioning the antenna within a portable communication device is maximized while the size of the portable communication device is minimized.
