In accordance with at least one aspect of this disclosure, a system includes a heat sink. In embodiments, the heat sink can include, a fin body, having a first face and a second face, one or more fins extending vertically from the fin body, and a clip disposed on one of the first face and/or the second face configured to attach to a heat generating component of a LRU to dissipate heat energy from the heat generating component of the LRU to an ambient environment. In embodiments, the heat generating component can include a bus bar, for example.

A connector assembly is provided and includes a guide shielding cage and a heat sink module. The guide shielding cage has at least one insertion space positioned inside. The heat sink module includes a heat dissipating member, a pressure applying elastic member, a lever member and a supporting elastic member. The heat dissipating member has a thermal coupling portion formed downwardly, the lever member is pivoted to the guide shielding cage, the lever member has a pushed end and a pressure applying end, the supporting elastic member upwardly and elastically supports the heat dissipating member. The heat dissipating member is capable of moving between a releasing position which is higher relative to the insertion space and an acting position which is lower relative to the insertion space and where the thermal coupling portion enters into the insertion space.

Systems and methods are disclosed relating to welding-type power supplies. In some examples, the power supplies may have no vents, which may help prevent environmental contaminants from entering the power supplies. Instead, the power supplies include one or more thermal interfaces configured to conduct heat generated by internal circuitry of the power supply from the interior of the power supply to an exterior of the power supply. Additionally, the thermal interface(s) may be configured for attachment to one or more exterior heat dissipating devices.

A semiconductor package assembly includes a circuit board, a heat dissipating element and a semiconductor device. The circuit board includes a conductive pattern. The heat dissipating element is located on the circuit board, where the heat dissipating element is connected to the conductive pattern.

This application relates to modifications and enhancements to assemblies used with integrated circuits. In the described embodiments, multiple thermal components (e.g., vapor chambers, fin stacks, heat pipes) can be used to provide a dual-sided thermal energy extraction solution for a circuit board and an integrated circuit located on the circuit board. The thermal components can provide thermal energy dissipation capabilities for additional heat-generating components on the circuit board. Additionally, multiple plates can provide a compression force used to maintain contact between the integrated circuit and the circuit board, and in particular, between contact pads of the integrated circuit and pins, or springs, of a socket located on the circuit board.

A circuit board assembly for electronic devices includes a circuit board having a first surface and a second surface opposite the first surface, and a heat sink carrier disposed on the first surface of the circuit board. The heat sink carrier includes at least one clamp portion. The assembly also includes a heat sink. The heat sink is positioned in the at least one clamp portion of the heat sink carrier to transfer heat from one or more electronic devices to the heat sink via the heat sink carrier.

In an apparatus for coupling integrated circuits to printed circuit boards, a backing plate with manufactured features on the top surface includes a module lid; a planar structure; a device seated in the planar structure, with the module lid in contact with the top surface of the device; and a backing plate that contains manufactured features on one side.
