  • Patent number: 8119206
    Abstract: A method of forming a negative coefficient of thermal expansion particle includes flattening a hollow sphere made of a first material, annealing the flattened hollow sphere at a reference temperature above a predetermined maximum use temperature to set a stress minimum of the flattened hollow sphere, and forming a coating made of a second material on the flattened hollow sphere at the reference temperature, the second material having a lower coefficient of thermal expansion than that of the first material, the negative coefficient of thermal expansion particle characterized by volumetric contraction when heated.

  • Patent number: 7823278
    Abstract: An interposer having one or more hollow electrical contact buttons disposed in a carrier. The interposer is formed by disposing sacrificial posts in vias of the carrier. The electrical contact buttons are formed on the sacrificial posts by a metallizing process in desired pattern using a mask. The sacrificial posts are made of a material that thermally decomposes upon application of heat without altering the carrier or the electrical contact buttons.

  • Patent number: 7736152
    Abstract: Methods for fabricating Land Grid Array (LGA) interposer contacts that are both conducting and elastic. Also provided are LGA interposer contacts as produced by the inventive methods. Provided is LGA type which utilizes a pure unfilled elastomer button core that is covered with an electrically-conductive material that is continuous from the top surface to the bottom surface of the button structure. In order to obviate the disadvantages and drawbacks which are presently encountered in the technology pertaining to the fabrication and structure of land grid arrays using electrically-conductive interposer contacts, there is provided both methods and structure for molding elastomer buttons into premetallized LGA carrier sheets, and wherein the non-conductive elastomer buttons are surface-metallized in order to convert them into conductive electrical contacts.

  • Publication number: 20090214780
    Abstract: A negative coefficient of thermal expansion particle includes a first bilayer having a first bilayer inner layer and a first bilayer outer layer, and a second bilayer having a second bilayer inner layer and a second bilayer outer layer. The first and second bilayers are joined together along perimeters of the first and second bilayer outer layers and first and second bilayer inner layers, respectively. The first bilayer inner layer and the second bilayer inner layer are made of a first material and the first bilayer outer layer and the second bilayer outer layer are made of a second material. The first material has a greater coefficient of thermal expansion than that of the second material.
