Abstract:
The invention relates to a transmission-line network of the foam stripline type. To reduce dielectric losses in the foam (6, 7), at least a part of the foam in the region of the stripline (1) is removed such that the wave properties of the transmission-line network are not impaired. Moreover the ducts (9, 10) that are formed may be used for the forced cooling of the stripline (1) using air or another cooling agent.

Abstract:
An electromagnetic interference shielding structure is disclosed. The electromagnetic interference shielding structure includes an insulating member covering at least one circuit element mounted on a printed circuit board (PCB), a shielding member covering the insulating member, and a heat dissipator having a surface adhering to the shielding member to transfer heat emitted from the at least one circuit element to a place where temperature is relatively low.
Abstract:
Aspects of the embodiments include an edge card and methods of making the same. The edge card can include a printed circuit board (PCB) comprising a first end and a second end, the first end comprising a plurality of metal contact fingers configured to interface with an edge connector, and the second end comprising a through -hole configured to mate with a post of a screw, the PCB further comprising an aperture proximate the second end or the PCB. The PCB can also include a thermal conduction element secured to the PCB, the thermal conduction element supporting an integrated circuit package, the integrated circuit package received by the aperture, wherein the thermal conduction element contacts the PCB proximate the through-hole and the thermal conduction element is configured to conduct heat from the integrated circuit towards the second portion of the printed circuit board.

Abstract:
Eine Mehrfunktionale Hochstromleiterplatte umfasst eine Hochstrom führende Stromleitungsschicht (4) und eine Schaltschicht (3), an die mindestens eine Wärmequelle (15, 21) angeschlossen ist, wobei Hochstrom führende Potentiale in die Schaltschicht (3) geführt sind.
Abstract:
A method for forming cooling channels in an interface for soldering to a semiconductor structure. The method includes: forming a metal seed layer on a surface of a substrate; patterning the metal seed layer into a patterned, plating seed layer covering portions of the substrate and exposing other portions of the substrate; using the patterned plating seed layer to form channels through the exposed portions of the substrate; and plating the patterned plating seed layer with solder. A heat exchanger having cooling channels therein is affixed to one surface of the interface and the semiconductor structure is soldered to an opposite surface of the interface. The cooling channels of the heat exchanger are aligned with the channels in the interface.
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.
