Publication number: 20080290510Abstract: A microelectronic package having integrated circuits is provided. The microelectronic package includes multiple dielectric laminate layers, copper circuitry between the dielectric laminate layers where the copper circuitry includes circuit traces, and ball grid arrays/land grid arrays operatively connected to the copper circuitry such that conduction occurs. Further, proximate to the connection of the copper circuitry and the ball grid arrays/land grid arrays, a protective copper tongue is below an extension of the circuit traces, such that the protective copper tongue prevents the circuit traces from being affected by cracking propagated in the dielectric laminate layers or the ball grid arrays/land grid arrays.Type: ApplicationFiled: May 23, 2007Publication date: November 27, 2008Applicant: INTERNATIONAL BUSINESS MACHINES CORPORATIONInventors: Jean Audet, Anson J.

Publication number: 20080266809Abstract: A thermal conducting mixture is provided which is used to make thermal conducting formulations such as a paste having a high thermal conductivity and a relatively low viscosity. The paste is used to provide a thermal conductor connection between an electronic component and a cooling device to increase the heat transfer rate between the component and the device cooling the electronic component. The formulation contains the mixture of thermally conductive particles in various particle size ranges typically dispersed in a non-aqueous dielectric carrier containing an antioxidant and a dispersant with the thermally conductive particles mixture being specially correlated in the mixture by volume % based on particle size range and by particle size ratio of each particle size range. The mixture may be used to make other similar products such as thermal gels, adhesives, slurries and composites, for electronic and cosmetics, pharmaceuticals, automotive, and like products.Type: ApplicationFiled: April 25, 2007Publication date: October 30, 2008Applicant: INTERNATIONAL BUSINESS MACHINES CORPORATIONInventors: Rajneesh Kumar, Steven P.

Publication number: 20070290378Abstract: The present invention provides chip containing electronic devices such as Multichip Ceramic Modules (MCM's) containing a plurality of chips on a substrate which chips are underfilled with a reworkable composition which allows one or more chips to be removed from the device and replaced. The reworkable compositions contain a base resin which is not cross-linkable and which forms a matrix with a linear curable component or preferably a combination of linear curable components which curable components are cross-linkable and when cured form a cross-linked domain in the base resin matrix. A suitable cross-linking catalyst such as Pt is used and optionally a filler preferably silane surface treated silica. The preferred base resin is linear polydimethylsiloxane and the preferred curable components are vinyl terminated linear poly dimethyl siloxane and hydrogen terminated linear poly dimethyl siloxane.Type: ApplicationFiled: June 20, 2006Publication date: December 20, 2007Applicant: INTERNATIONAL BUSINESS MACHINES CORPORATIONInventors: Jeffrey T.

Patent number: 7079393Abstract: A cooling system for an electronic component on a component carrier is provided. The system includes a frame, a spray manifold, and a sealing member. The frame has an opening and is connectable to the component carrier so that an annular area is defined between the opening and the electronic component. The spray manifold is sealed over the opening to define a spray area over a back surface of the electronic component. The spray manifold sprays a cooling fluid on the back surface. The sealing member seals the annular region so that input/output connectors on the component carrier are isolated from the cooling fluid.Type: GrantFiled: November 16, 2004Date of Patent: July 18, 2006Assignee: International Business Machines CorporationInventors: Evan G. Colgan, Frank L. Pompeo, Glenn G. Daves, Hilton T. Toy, Bruce K. Furman, David L. Edwards, Michael A. Gaynes, Mukta G. Farooq, Sung K. Kang, Steven P. Ostrander, Jaimal M.

Patent number: 6908025Abstract: A process and apparatus for preparing an MCM for hat removal where the hat includes a piston thermally coupled to a corresponding chip. The apparatus includes a heater positioned to reflow a joint between the piston and a base of the hat; and a retractor for biasing the piston away from the corresponding chip. Implementation of the apparatus and process prevent a piston, as it moves across the top of a corresponding chip during mechanical shear to remove the hat, to impact chip(s) and surrounding components. In addition, since piston(s) are retracted, the likelihood of piston impact with or cracking of a chip is reduced. In addition, cutting into a corresponding chip having a tilted back surface is prevented. The need to replace chips and other electronic components when making other repairs may, therefore, be greatly reduced.Type: GrantFiled: June 26, 2003Date of Patent: June 21, 2005Assignee: Internatioanl Business Machines CorporationInventors: Patrick A. Coico, Steven P. Ostrander, Sudipta K. Ray

Patent number: 6827505Abstract: An optical-electronic package for an electronic device provides electrical connections to the electronic device and optical fiber connections to the electronic device. The package includes a high thermal conductivity base which has a pedestal to support and provide heat transfer connection to the electronic device. A seal band is formed on the base and a casing is bonded to the seal band. The casing has side feedthroughs for the electrical connections from the electronic device, and the casing has top feedthroughs or grooves for the optical fiber connections from the electronic device. A lid is hermetically sealed to the top of the casing. The lid has retractable means for forming a bend in the optical fibers to provide strain relief when the lid is placed on the casing. The retractable means for forming a bend in the optical fibers is retractable once the lid is sealed on the casing.Type: GrantFiled: December 16, 2002Date of Patent: December 7, 2004Assignee: International Business Machines CorporationInventors: Subhash L.

Patent number: 6821026Abstract: A redundant configurable VCSEL laser array optical light source which provides for integrating optical communications capabilities into manufacturing processes for a substrate or submount such as a silicon or ceramic substrate, a multi-chip module, a package board, backplane or similar component. Multiple, spatially proximate lasers and photodetectors are provided as part of an optical transmitter or receiver module to simplify assembly of the module, particularly alignment of a laser or photodetector to an optical fiber or waveguide. A feedback loop and control logic select those laser(s) or photodiodes(s) which are most strongly coupled to the transmission medium to produce the best signals. This approach greatly simplifies optical alignment, to improve yield and relax mechanical tolerances, leading to lower assembly costs and higher manufacturing yields.Type: GrantFiled: September 4, 2002Date of Patent: November 23, 2004Assignee: International Business Machines CorporationInventors: William T. Devine, Jeffrey A. Kash, John U. Knickerbocker, Steven P. Ostrander, Jeannine M. Trewhella, Ronald P. Luijten
