Abstract:
According to various aspects, exemplary embodiments are disclosed of soft and/or flexible electromagnetic interference (EMI) shields. In an exemplary embodiment, a shield is suitable for use in providing EMI shielding for one or more components on a substrate. The shield generally includes one or more contacts configured for installation on the substrate and an electrically-conductive cover configured for installation on the contact(s).
Abstract:
An assembly (1000) includes a substrate (1002) and a heat emissive electrical component (1001) disposed on the substrate. A shield (1003) is disposed on the substrate, thereby enclosing the heat emissive electrical component. A display assembly (101) is disposed above the shield. A compressible pad (1004) is disposed between the shield and the display assembly. The compressible pad defines an aperture (1005) above the heat emissive electrical component. The aperture can have dimensions that are a function of a shield area and a heat emissive electrical component area.
Abstract:
본 발명은 롤 공급 금속판재를 이용하여 프레스 가공방식으로 쉴드캔을 제조하는 방법 및 이를 통해 제조된 쉴드캔에 관한 것이다. 본 발명은 기존에 쉴드캔과 같이 일부에서 타공이 이루어져야 하는 전자부품에 대하여 프로그레시브 프레스 방식을 적용하는데 있어서 이송시 발생하는 지속적인 누적오차로 인하여 적용이 어려웠던 문제점을 해결하기 위하여 프레스 적용 이전에 피어싱 공정을 통한 피치홀을 생성하고 상기 피치홀의 간격으로 금속판재를 이송시켜 일정간격으로 금속판재가 이송되는 동시에 각 피치홀마다 프레스에 의한 타공위치를 초기화시킬 수 있어 오차가 누적되는 것을 방지함으로써, 프로그레시브 프레스 방식의 적용시에도 제품 수율과 품질을 극히 향상시킬 수 있는 효과가 있다.
Abstract:
Electronic components on a substrate may be shielded using electromagnetic shielding structures. Insulating materials may be used to provide structural support and to help prevent electrical shorting between conductive materials and the components. The shielding structures may include compartments formed using metal fences that surround selected components or by injection molding plastic. The shielding structures may be formed using metal foil wrapped over the components and the substrate. Electronic components may be tested using test posts or traces to identify components that are faulty. The test posts or traces may be deposited on the substrate and may be used to convey test signals between test equipment and the components. After successful testing, the test posts may be permanently shielded. Alternatively, temporary shielding structures may be used to allow testing of individual components before an electronic device is fully assembled.
Abstract:
The invention relates to a ground connection system (1) for electronic components that are exposed to vibrations. Said system comprises a frame (2), at least one printed circuit board (4) and a casing cover (3). One or more electrically conducting terminal elements (5) are arranged on the casing cover (3) in such a manner that they can resiliently engage in at least one recess (6) of the frame (3) and establish an electrically conducting connection between the casing cover (3) and the frame (2).
Abstract:
An RF module (20) adapted for direct surface mounting to the front end of a picocell or microcell . The module includes a circuit board (22) with a plurality of electrical components mounted thereon and defining respective RF signal transmit and receive sections. The signal transmit section is defined by at least a transmit bandpass filter (25) , a power amplifier (26) , an isolator (28) , a coupler (30) , and a duplexer (34) . The signal receive section is defined by at least the duplexer (34) , a receive low pass filter (36) , a low-noise amplifier (39) , and a receive bandpass filter (40) . A lid (45) covers selected ones of the electrical components except for at least the power amplifier. Through-holes (136) in the circuit board below the power amplifier allow for the transfer of heat from the power amplifier.
