Abstract: A socket for connecting to an integrated circuit module containing pin grid array contacts and land grid array contacts thereon. The socket has a first portion containing openings therein for the pin grid array contacts and a second portion for contacting the land grid array contacts. The first portion of the socket is disposed around the second portion of the socket, and the second portion is movable with respect to the first portion. The second portion is located in a position wherein the pin grid array contacts on the integrated circuit module are received in the openings in the first portion before the land grid array contacts on the integrated circuit module contact the second portion, the second portion being biased toward the integrated circuit module by a spring.

Abstract: An adjustable size hot plug assembly includes a frame, an actuator and at least one arm connected thereto. The arm includes an adjustable clip and a fixed clip to retain a printed circuit board. Where more than one arm is employed (preferably three are employed in the invention), the middle arm and one end arm are adjustable toward or away from one another and toward or away from the other end arm which may be fixed. The invention allows the hot plug assembly to be universal in that it can be adapted to fit any Peripheral Component Interconnect (PCI) card.

Abstract: A cold plate, planar in shape, is machined to provide an interior cavity having a plurality of thermally conductive members which transfer any thermal energy absorbed by the cold plate to a chilled water stream flowing through the interior cavity. Electronic cards are mechanically and thermally married to copper conduction plates which mount on a surface of the cold plate. The cold plate can hold up to nineteen pairs of conduction plate/electronic card assemblies. Thermal energy generated by the electronic circuit cards flows into the conduction plate and then into the chilled water stream flowing in cold plate. The chilled water is provided by a cooling system as known in the art. The cold plate also provides a large central through-hole through which the electronic cards are electrically connected to a computer system. The cold plate through-hole allows the cold plate to enjoy close proximity to the thermal source providing a path of high conductance for the thermal energy to be dissipated.
