A system and method for cooling a plurality of connectors interfacing electrical and optical signals to circuit boards in an electronics cabinet, such as backplane connectors routing signals to circuit boards housed in card cage assemblies. Heat pipes coupled to the connectors efficiently remove heat from the connectors and sink the connector heat to a cold junction of a liquid cooling system, which cooling system may also extract heat from air flow cooling the circuit boards such that the system is room neutral, meaning that the ambient temperature remains constant during operation of the system. The heat connector cooling system is effective where connectors are outside of an air flow cooling envelope that may cool the circuit boards.

A system and method for cooling individual electronic components utilizes individual manifolds to create individual flows of a negatively pressurized cooling fluid. This permits components with significantly different cooling loads to be located immediately adjacent each other on a circuit board, but without loss of space and computation time efficiencies, because cooling the components individually avoids heat generated by each component from adversely affecting the performance of the cooling system for adjacent components. A heat sink can be coupled to the components for increased heat transfer, and a preferred design of heat sink both dissipates heat and directs the flow of the fluid in an optimum manner.

System and method for cooling electronic components

An information handling system includes stacks of printed circuit boards interconnected using an interconnection system. The printed circuit boards include network boards, system interface boards, memory boards, and central processing unit boards. The interconnection system for electrically connecting the various printed circuit boards includes a set of interconnection modules placed adjacent one another to form a substantially aligned row. The interconnection modules can be used to connect one stack to an orthogonally oriented stack or to a parallel oriented stack. The printed circuit board used in the interconnection system includes an inner rail positioned near the edge of the printed circuit board, an outer rail positioned near the edge of the printed circuit board, and an alignment stop attached to or positioned near one of the inner or outer rail. The most distant interconnection module of a row of aligned modules includes a spring attached thereto. The spring biases the set of interconnection modules toward the alignment stop to lessen the amount of stack up tolerance or float between the individual modules in the aligned row of interconnection modules. Electrical contact points located between the inner and the outer rail. The modules include alignment feet which have corresponding contact points. The inner and outer rail includes slots therein for clearance of the interconnection modules with the contact points.

Stop align lateral module to module interconnect

The invention comprises a plurality of stacked planar processing circuit boards surrounded on at least one side by a plurality of memory boards located substantially perpendicular to the planar processing boards, the processing and memory boards connected by orthogonal interconnect modules. The orthogonal interconnect modules allow closely-spaced orthogonal connection of the processing boards to the memory boards. The memory boards are of a densely packed design having a plurality of removeable memory chip stacks located on the memory boards.

High density interconnect apparatus

An apparatus and method of making a beam of directed energy used to bond leads to bonding areas is disclosed. The masking tool preferably includes a groove adapted to allow the beam to strike the lead while masking the surrounding substrate to prevent damage to it. The tool preferably reflects the energy striking it away from the substrate. The method can include the use of an external heat source to provide heat to the bonding process or, in the alternative, provide heat sinking to protect the electrical components from heat damage. Alternate embodiments of the tool can include a plurality of grooves or slots to allow scanning of the beam in the bonding process.
