Patent number: 7380409Abstract: An isolation valve assembly, a coolant connect/disconnect assembly, a cooled multi-blade electronics center, and methods of fabrication thereof are provided employing an isolation valve and actuation mechanism. The isolation valve is disposed within at least one of a coolant supply or return line providing liquid coolant to the electronics subsystem. The actuation member is coupled to the isolation valve to automatically translate a linear motion, resulting from insertion of the electronics subsystem into the operational position within the electronics housing, into a rotational motion to open the isolation valve and allow coolant to pass. The actuation mechanism, which operates to automatically close the isolation valve when the liquid cooled electronics subsystem is withdrawn from the operational position, can be employed in combination with a compression valve coupling, with one fitting of the compression valve coupling being disposed serially in fluid communication with the isolation valve.Type: GrantFiled: September 30, 2004Date of Patent: June 3, 2008Assignee: International Business Machines CorporationInventors: Levi A.

Patent number: 6262582Abstract: A fixture to hold an electronic substrate having probe areas on a top surface. The top surface of the electronic substrate is left open to provide a maximum area to couple interconnect wires for a device under test. In addition, a bottom surface of the substrate is left open to provide a maximum area to couple with a probe card in one embodiment, or a test head in another embodiment. This open bottom and open top minimize the mechanical interference with electrical connections. The substrate is planarized to a frame by one or more clamps that are attached to the frame. The clamps provide adjustment of the pressure down on the substrate in a Z-axis direction which is normal to the top surface of the substrate for providing a good connection with a planar card. In addition, the clamps provide adjustment in the an X-Y plane parallel to the frame and rotational correction about the Z-axis.Type: GrantFiled: October 15, 1999Date of Patent: July 17, 2001Assignee: International Business Machines CorporationInventors: Dennis R.
