20080220998 | REVERSIBLE THERMAL THICKENING GREASE - A reversible thermal thickening grease for microelectronic packages, in which the grease contains filler particles; at least one polymer; and a binder; in which the filler particles are dispersed within the binder, in which one or more segments of the at least one polymer may be attached to the filler particles prior to dispersion in the binder, and in which the polymer collapses at temperatures below a Theta temperature and swells at temperatures above a Theta temperature. During the operation of a microelectronic package, grease pump-out and air proliferation are minimized with use of the reversible thermal thickening grease, while grease fluidity is retained under repetitive thermal stresses. | 09-11-2008 |
20080225484 | THERMAL PILLOW - Methods, apparatus and assemblies for enhancing heat transfer in electronic components using a flexible thermal pillow. The flexible thermal pillow has a thermally conductive material sealed between top and bottom conductive layers, with the bottom layer having a flexible reservoir residing on opposing sides of a central portion of the pillow that has a gap. The pillow may have roughened internal surfaces to increase an internal surface area within the pillow for enhanced heat dissipation. In an electronic assembly, the central portion of the pillow resides between a heat sink and heat-generating component for the thermal coupling there-between. During thermal cycling, the flexible reservoir of the pillow expands to retain thermally conductive material extruded from the gap, and then contracts to force such extruded material back into the gap. An external pressure source may contact the pillow for further forcing the extruded thermally conductive material back into the gap. | 09-18-2008 |
20080299707 | THERMAL PASTE CONTAINMENT FOR SEMICONDUCTOR MODULES - A semiconductor module structure and a method of forming the semiconductor module structure are disclosed. The structure incorporates a die mounted on a substrate and covered by a lid. A thermal compound is disposed within a thermal gap between the die and the lid. A barrier around the periphery of the die extends between the lid and the substrate, contains the thermal compound, and flexes in response to expansion and contraction of both the substrate and the lid during cycling of the semiconductor module. More particularly, either the barrier is formed of a flexible material or has a flexible connection to the substrate and/or to the lid. The barrier effectively contains the thermal compound between the die and the lid and, thereby, provides acceptable and controlled coverage of the thermal compound over the die for heat removal. | 12-04-2008 |
20090109628 | Chip Cooling System with Convex Portion - Integrated circuit chip cooling methods and systems are disclosed. A method for cooling an integrated circuit chip may comprise: providing a cooling mechanism; positioning an interface medium between the cooling mechanism and the integrated circuit chip; and interfacing the cooling mechanism and the integrated circuit chip through the interface medium; wherein at least one of the cooling mechanism, the integrated circuit chip, or the interface medium includes a convex portion on an interface surface thereof. | 04-30-2009 |
20100147497 | PATTERNED METAL THERMAL INTERFACE - The present invention is a patterned metal thermal interface. In one embodiment a system for dissipating heat from a heat-generating device includes a heat sink having a first surface adapted for thermal coupling to a first surface of the heat generating device and a thermal interface having at least one patterned surface, the thermal interface being adapted to thermally couple the first surface of the heat sink to the first surface of the heat generating device. The patterned surface of the thermal interface allows the thermal interface to deform under compression between the heat sink and the heat generating device, leading to better conformity of the thermal interface to the surfaces of the heat sink and the heat generating device. | 06-17-2010 |
