Patent number: 9301430Abstract: An electronic module is provided in which a chip is disposed over a substrate and electrically connected to the substrate by a plurality of electrical connect structures disposed between the chip and the substrate. A heat distributor, fabricated of a thermally conductive material, is disposed between the chip and the substrate and sized to extend beyond an edge of the chip to facilitate conduction of heat laterally out from between the chip and substrate. The heat distributor includes openings sized and positioned to allow the electrical connect structures to pass through the heat distributor without electrically contacting the heat distributor. The heat distributor is electrically isolated from the electrical connect structures, the chip and the substrate. In one implementation, the heat distributor physically contacts a thermally conductive enclosure of the electronic module to facilitate conduction of heat from between the chip and substrate to the enclosure.Type: GrantFiled: September 9, 2013Date of Patent: March 29, 2016Assignee: INTERNATIONAL BUSINESS MACHINES CORPORATIONInventors: Arvind K. Sinha, Kory W. Weckman

Publication number: 20160007515Abstract: Embodiments of the invention relates to a method for rework of a BGA package. Memory shape material is placed adjacent to a plurality of solder joints of the package. Stimulation is applied to the material, with the stimulation causing the material to change from a non-stimulated shape to a stimulated shape. This stimulation causes an expansion of the material. As the material expands, it exerts a tensile force on the BGA package and an adjacently positioned carrier, causing a separation of the two components, while mitigating collateral heat of adjacently positioned components.Type: ApplicationFiled: August 26, 2015Publication date: January 7, 2016Applicant: INTERNATIONAL BUSINESS MACHINES CORPORATIONInventors: Eric V. Kline, Arvind K. Sinha

Publication number: 20150318231Abstract: An apparatus for cooling an electrical heat source is disclosed. A heat exchanger has two principal sub-assemblies. A closed-loop fluid flow is provided through a second sub-assembly, disposed next to a heat source. An open-loop fluid flow is provided though a first sub-assembly in communication with a second sub-assembly. Each of the first and second sub-assemblies has a rotational element. The fluid flow entering the first sub-assembly rotates the first rotational element, and magnetic communication between the rotational elements causes movement of the second rotational element, thereby achieving fluid movement within the second sub-assembly. Operationally, the closed-loop sub-assembly removes heat from the heat source and transfers it to the open-loop sub-assembly for subsequent heat transfer in a downstream fluid flow.Type: ApplicationFiled: July 10, 2015Publication date: November 5, 2015Applicant: International Business Machines CorporationInventors: Maurice F.
