Abstract:
A method of providing support for an electronic component (17) in an electronic device comprising a PCB (printed circuit board) (14) and a structural element (15) covering at least a part of the PCB (14). The method comprises the steps of mounting the electronic component (17) on the PCB (14), applying an elastically compressible and shock-absorbing material (18) to the structural element (15) at an area (22) thereof that is adapted to cover the component (17), and assembling the PCB (14) and the structural element (15) in such manner that the elastically compressible and shock-absorbing material (18) exerts a pressure on the electronic component (17) towards the PCB (14). An electronic device comprising an elastically compressible and shock-absorbing material between the structural element and the PCB is also disclosed.
Abstract:
A multi-functional metal shield case and a method for making the same are provided. The multi-functional metal shield case includes a metal main body and an electrically non-conductive and heat conductive silicon layer. The metal main body includes a base and sidewalls integrally bent along edges of the base, and the electrically non-conductive and heat conductive silicon layer is formed on inner sides of the base and the sidewalls. Accordingly, heat can be rapidly transferred to the metal main body and emitted to an outside. Since the heat conductive silicon layer is non-conductive, an electric shock does not occur between the electronic component and the metal shield case. Further, since the heat conductive silicon layer is in contact with the electronic component, heat can be transferred more rapidly.
Abstract:
The invention relates to a screen that prevents the penetration of electromagnetic radiation towards or from electric or electronic circuit elements of an electric circuit that are arranged on a substrate. The inventive screen consists of a metal housing that comprises a frame (2) configured by lateral walls (21 to 24) and inner walls (41, 42) that are located within the frame (2) and that define at least one chamber. Said inner walls together with the lateral walls (21 to 24) are punched from one piece of metal. The screen further comprises a lid that can be linked with the lateral walls (21 to 24) and/or the inner walls (41, 42). The lateral walls (21 to 24) and the inner walls (41, 42) consist of perpendicular lateral wall sides (211 to 242) and inner wall sides (411 to 422). Respective side portions, namely the narrow lateral wall sides (212, 222, 232, 242) and the narrow inner wall sides (412, 422) are linked with the substrate and their width is adapted to the width of the soldered tracks that are located on the substrate.
Abstract:
Electromagnetic interference (EMI) shields are provided to be placed on and cover an electronic component. The EMI shields at least partially surround the electronic component, and include an undulated edge. In some cases, an EMI absorbing material is placed along the undulated edge.
Abstract:
Der Frequenzumrichter weist eine Umhausung auf, in welcher elektrische und elektronische Bauelemente (5, 6, 7, 22) angeordnet sind und die zumindest teilweise als Faradayscher Käfig ausgebildet ist. Innerhalb der Umhausung sind mindestens zwei Faradaysche Käfige (4, 9, 15, 29) vorgesehen, um die EMV zu verbessern.
Abstract:
The present invention relates to a shield case and an antenna set comprising the same, wherein the shield case includes a shield surface for shielding embedded electronic elements against electromagnetic wave, a fixing unit coupled with a substrate mounted with the electronic elements, signal receivers for receiving a signal of desired frequency, and two strip antennas connected to a border of the shield surface, each antenna facing the other across the shield surface.
Abstract:
The present invention relates to a one-piece shielding hood with one or more pins (100) for attaching a second device, a blank of a supple material and an arrangement of a first and a second device. The one-piece shielding hood is adapted to sheath a first device mounted on a carrier surface in an interior of the shielding hood and to reduce electromagnetic interference between electromagnetic radiation in an exterior of the shielding hood and electromagnetic radiation in the interior of the shielding hood. The shielding hood is adapted for mounting on the carrier surface. According to the invention the shielding hood further comprises one or more pins (100) for attaching a second device to a side of the shielding hood facing to the exterior of the shielding hood, wherein the pins (100) are at least partially cut and bent out of the shielding hood. This allows both shielding a first device of a first printed circuit board and connecting a second device to the first printed circuit board with means of single one-piece shielding hood.
Abstract:
An RF module adapted for direct surface mounting to the front end of a picocell or microcell. The module includes a circuit board 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, a power amplifier, an isolator, a coupler, and a duplexer. The signal receive section is defined by at least the duplexer, a receive low pass filter, a low-noise amplifier, and a receive bandpass filter. A lid covers selected ones of the electrical components except for at least the power amplifier. Through-holes in the circuit board below the power amplifier allow for the transfer of heat from the power amplifier.
