  • Patent number: 9312231
    Abstract: A semiconductor device package that incorporates a combination of ceramic, organic, and metallic materials that are coupled using silver is provided. The silver is applied in the form of fine particles under pressure and a low temperature. After application, the silver forms a solid that has a typical melting point of silver, and therefore the finished package can withstand temperatures significantly higher than the manufacturing temperature. Further, since the silver is an interfacial material between the various combined materials, the effect of differing material properties between ceramic, organic, and metallic components, such as coefficient of thermal expansion, is reduced due to low temperature of bonding and the ductility of the silver.

  • Patent number: 8492004
    Abstract: The invention provides a friction joining structure comprising steel products, a friction joining steel plate inserted there between, and a fastening device, which are mutually friction joined by a compressive force derived from the fastening device. A portion of projected streaks on the friction joining steel plate is designed to have a Vickers hardness at least 3 times greater than the surface of the steel products, which allows the projected streaks to more easily enter the steel products thereby increasing the friction coefficient between the steel products. The friction joining structure is constituted by a slip resistance mechanism which can be easily validated from a theoretical or an experimental point of view and is also small in variance of the friction coefficient. Therefore, a friction coefficient used in design can be set at a high value with high accuracy to realize a rational design.

    Abstract: Superalloy components are joined by mating a recess formed in one component with a corresponding projection formed in another component along a contact surface. The components are compressed along the contact surface and resistance heat brazed to each other. Current is passed between the components at a selected flow rate and application time until brazing alloy melting occurs along the contact surface, and they are mutually affixed to each other. When repairing a damaged surface portion of a superalloy material component, the damaged portion is removed to form an excavated recess. A repair splice is formed, preferably of a same material with similar mechanical structural properties, having a mating projection with profile conforming to the corresponding recess profile. The splice and substrate are resistance heat brazed under compression pressure until brazing alloy melting occurs along the contact surface, so that they are mutually affixed.

  • Patent number: 7968144
    Abstract: A system for forming a surface coating on an outer surface of a foam for use with cooling system of turbine engines. The system may include removing filler from the outer surface of the foam to expose a porous structure of the foam, whereby portions of the porous structure extend outwardly from a newly formed outer surface of the filler. A surface layer may be applied to the outer surface of the filler and exposed portions of the porous structure, whereby the surface layer is attached to the porous structure at least in part due to mechanical interaction with the portions of the porous structure extending outwardly from the newly formed outer surface of the filler. The filler material may then be removed from the porous structure.

  • Patent number: 7250221
    Abstract: A method of producing a clad metal ingot suitable for rolling to form a clad metal sheet, and the clad metal ingot so produced. The method involves providing a solid core ingot having an upper side with a rolling face thereon having cavities extending inwardly into the ingot from the rolling face. All or all-but-one of the cavities are blocked against molten metal entry and casting cores extending outwardly from the rolling surface are provided in alignment with the cavities. Molten cladding metal is cast on the rolling face around the casting cores to produce a composite ingot and the casting cores are removed to produce voids in the cladding layer, and the cavities are unblocked. The resulting interconnected cavities and voids are filled with a molten metal to form cast-in-place metal lugs keying or pinning the cladding layer to the core ingot.

  • Patent number: 7097914
    Abstract: A plate-shaped composite material has a first member and a second member. The first member is an expanded metal formed of a metal plate. The coefficient of linear expansion of the metal plate is less than or equal to 8×10?6/degrees Celsius. The first member suppresses thermal expansion of the composite material. The coefficient of thermal conductivity of the second member is greater than or equal to 200 W/(m×K). The second member maintains the coefficient of thermal conductivity of the composite material. This structure provides a reliable coefficient of thermal conductivity and high strength. The structure is suitable for a cooling substrate on which electronic elements such as semiconductors are mounted.

  • Patent number: 6994917
    Abstract: A plate of an expanded metal and two metal plates are overlaid on one another. The expanded metal plate has a plurality of meshes. The linear expansion coefficient of the expanded metal is equal to or less than 8×10?6/° C., and the thermal conductivity of the metal plates is equal to or more than 200 W/(m·K). Then, the metal plates and the expanded metal plate are subjected to hot rolling to be rolled and joined. The rolling and joining are performed in two stages. In the first stage, the meshes of the expanded metal plate are filled with the material of the metal plates. In the second stage, the rolling and joining are performed such that the composite material has a predetermined thickness. The volumetric ratio of the expanded metal plate to the composite material is in a range between 20% and 70%, inclusive. The composite material, which has an improved thermal conductivity and strength and is suitable for heat dissipating substrate, is manufactured at a reduced cost.

  • Patent number: 6991856
    Abstract: Reactive foils and their uses are provided as localized heat sources useful, for example, in ignition, joining and propulsion. An improved reactive foil is preferably a freestanding multilayered foil structure made up of alternating layers selected from materials that will react with one another in an exothermic and self-propagating reaction. Upon reacting, this foil supplies highly localized heat energy that may be applied, for example, to joining layers, or directly to bulk materials that are to be joined. This foil heat-source allows rapid bonding to occur at room temperature in virtually any environment (e.g., air, vacuum, water, etc.). If a joining material is used, the foil reaction will supply enough heat to melt or soften the joining material, which upon cooling will form a strong bond, joining two or more bulk materials.

The Ni-based metal layer has a maximum-to-minimum thickness ratio T1/T2 of 1.4 to 15. The lid material is produced by press-bonding a Ni-based metal foil onto a core sheet for formation of the Ni-based metal layer on the core layer, then diffusion-annealing the Ni-based metal layer and the core layer, and press-bonding a brazing material foil onto the Ni-based metal layer with a reduction ratio of 30 to 65%.
