Patent number: 8107800Abstract: An article supports a workpiece during thermal processing. At least three elongated support members, e.g., support pins, extend upwardly from an element such as support arms for supporting the workpiece. Each of the support members includes a first portion adjacent to the workpiece. A second portion extends downwardly from the first portion. The first portion can have a thermal response faster than the thermal response of the workpiece and the second portion can have a slower thermal response. A removable element may be mounted to the support member for adjusting the thermal response of the support member. With removable elements, the support members can be adjusted to cause no net transfer of heat to or from the workpiece.Type: GrantFiled: January 8, 2008Date of Patent: January 31, 2012Assignee: International Business Machines CorporationInventors: Raschid J.

Patent number: 7095614Abstract: Methods of engaging an electronic module interconnected to a circuit board to a heat sink using clamping assemblies that maintain integrities of an interconnection grid array and the electronic module. A loading block having a plurality of legs is positioned at a backside of the module toward the circuit board in a location corresponding to a central area of the interconnection grid array. A spring having a central fastening means and plurality of peripheral securing means is positioned adjacent the loading block. The fastening means is actuated whereby central backside compressive forces are directed at and force the loading block against the circuit board, while forces are applied to the securing means for engaging the securing means into the heat sink such that the electronic module is engaged with the heat sink. The clamping assembly relocates the regions of highest compression on the interconnection array, thereby maintaining the integrity thereof.Type: GrantFiled: April 20, 2004Date of Patent: August 22, 2006Assignee: International Business Machines CorporationInventor: Lewis S.

Patent number: 6678949Abstract: A structure for mounting electronic devices. The structure uses a non-conductive, compliant spacer interposed between an underlying carrier and an overlying thin film. The spacer includes a pattern of through-vias which matches opposing interconnects on opposing surfaces of the carrier and the thin film. In this way, solder connections can extend in the through-vias to electrically connect the thin film to the carrier and smooth out topography. In a related process for forming the structure, the thin film is built on a first sacrificial carrier and then further processed on a second sacrificial carrier to keep it from distorting, expanding, or otherwise suffering adversely during its processing. The solder connections between the thin film and the carrier are formed using a closed solder joining process. The spacer is used with laminate cards to create thermal stress release structures on portions of the cards carrying a thin film.Type: GrantFiled: June 21, 2001Date of Patent: January 20, 2004Assignee: International Business Machines CorporationInventors: Chandrika Prasad, Roy Yu, Richard L. Canull, Giulio DiGiacomo, Ajay P. Giri, Lewis S. Goldmann, Kimberley A. Kelly, Bouwe W. Leenstra, Voya R. Markovich, Eric D. Perfecto, Sampath Purushothaman, Joseph M. Sullivan
