Abstract: The connector portion of a flex connector may be integrated into a socket, by forming a complete cutout in the socket in which the connector is located, or by forming the socket with a portion having a reduced thickness relative to the rest of the socket, with the connector being positioned in this portion of reduced thickness between the socket and an MLB. Another flex connector may be formed vertically above the first flex connector, mounted to the top surface of the package and clamped in place by a heat sink on top of the stack. Providing both top and bottom flex connectors may multiply the number of available connections for a given footprint. A heatsink positioned on top of the stack may include a spring assembly on a bottom portion to engage specified portions of the stack with a predefined force to ensure correct loading.

Abstract: A heat sink may be clamped to a thermoelectric cooler and vapor chamber using a U-shaped retention band. The band may attach underneath the vapor chamber, extending around the thermoelectric cooler, and over a heat sink. The heat sink may include a plate to distribute the force of the band across the heat sink. Bolts may be utilized to transfer the force from the free ends of the U-shaped retention band to a vapor chamber support frame. Thus, in some embodiments of the present invention, a thermoelectric cooler may be clamped to a heat sink without wasting heat transfer area through the use of bolts, without unnecessary bending, and without requiring a relatively thick base on the heat sink.

Abstract: A heat sink assembly may be plugged into a receiving element in a printed circuit board. A retention element includes upper and lower portions. The lower portion may be plug locked onto a printed circuit board. The upper portion then telescopes into and releaseably locks in the lower portion. The upper portion may include a rod which may be rotated to free the upper portion from the lower portion for disassembly.
