Abstract:
A low Z profile consolidated thermal module suitable for securing and removing excess heat generated by an integrated circuit (208) mounted to a printed circuit board (214) and operating in a compact computing environment is disclosed. The consolidated thermal module comprises a heat removal assembly (202, 204, 206) with a reduced footprint and disposed on a first surface of the printed circuit board and in thermal contact with the integrated circuit. A retaining mechanism (210) is disposed on a second surface of the printed circuit board and a backer plate (218) is disposed between the retaining mechanism and the printed circuit board. At least one fastener (212) secures the heat removal assembly to the backer plate and the retaining mechanism, wherein the retaining mechanism causes a substantially uniform retaining force to be applied across the backer plate, thereby minimizing an amount of torque applied to the integrated circuit.
Abstract:
A sheet-shaped flexible electronic device (10;20;40) comprising a reinforced portion (11;25), wherein a boundary (12;24) between the reinforced portion (11;25) and a portion (13;26) of the flexible electronic device adjacent to the reinforced portion (11;25) is at least macroscopically curved to inhibit bending of the flexible electronic device (10;20;40) along the boundary (12;24). Hereby, the robustness and reliability of the sheet-shaped electronic device can be improved.

Abstract:
A strain-resistant electrical connection and a method of making the same is provided. An antenna (36, 38) or other conductive lead is connected to a circuit (32) in a manner that makes the connection more resistant to mechanical stresses such as movement or rotation of the antenna (36, 38) or conductive lead relative to the circuit (32). The antenna (36, 38) or conductive lead is at least partially coiled to provide additional ability to withstand mechanical stresses. The antenna (36, 38) or conductive lead may be encase along with is connected circuit in an elastomeric material.
Abstract:
A microelectronic spring contact for making electrical contact between a device and a mating substrate and method of making the same are disclosed. The spring contact has a compliant pad adhered to a substrate of the device and spaced apart from a terminal of the device. The compliant pad has a base adhered to the substrate, and side surfaces extending away from the substrate and tapering to a smaller end area distal from the substrate. A trace extends from the terminal of the device in a coil pattern over the compliant pad to its end area, forming a helix. At least a portion of the compliant pad end area is covered by the trace, and a portion of the trace that is over the compliant pad is supported by the compliant pad. In an alternative embodiment, the pad is removed to leave a freestanding helical contact.
Abstract:
An interconnection element (255) is described including a first part (405) for connection to a first port of a transmission line (205) and a second flexible part (410) for connection to a second port of the transmission line (210), wherein in a first operating mode the first part is fixed to the first port and the second flexible part is biased such that it contacts the second port to interconnect the first and second port via the interconnection element; and in a second operating mode the first part is fixed to the first port and the second flexible part is forced away (105, 240) against the bias from the second port such that an open circuit is created between the first port and the second port.
Abstract:
An electronic device (100) includes an exterior portion (110) of a conductive material, a circuit portion (120) including circuit elements, and a protection circuit portion (130) connected between the exterior portion and the circuit portion. The protection circuit portion (130) includes a switching unit (132) to intercept leakage current that flows from the circuit portion and leaks to the exterior portion, and a conversion unit (131) to reduce a voltage level of an electrostatic component that flows through the exterior portion and to transfer the electrostatic component to the switching unit.
Abstract:
The invention relates to a printed board arrangement (20) having at least two printed boards (11; 12') resting side-by-side on a joint, electrically conductive base plate (13'), and which with two edges are positioned opposite each other thus forming a gap (14), and which are interconnected, bridging the gap (14) by way of electrical connections (21) for transmitting highest frequencies. With a printed board arrangement such as this, high-frequency suitable electrical connections between the printed boards are established when the printed boards are installed on the base plate, in a simple and space-saving manner and without the need for any additional or subsequent work such that the respective electrical connections are established via at least one contacting element (21), by way of which the printed boards detachably establish electrical contact during the installation on the base plate (13').
