摘要： A metal alloy feedstock and method for metal injection molding is disclosed. The alloy includes at least two components, such as a first component and a second component. The first component has a first melting point and the second component has a second melting point higher than the first melting point. The first melting point and the second melting point match to the temperature gradient of the heated barrel of an injection molding machine whereby when fed into the injection molding machine the first component melts prior to the second component melts and enables the second component to solute into the first component. Additional components may also be used.

摘要： The present invention discloses a method of providing an integral thermal interface on an interface surface of a heat dissipation device, such as a heat sink. In accordance with the present invention, the phase change material is applied directly onto the interface surface of the heat sink to form an integral interface layer directly on the heat sink during the manufacturing process. This process includes the steps of providing a heat dissipating device having an interface surface, liquefying the phase change material at a controlled temperature so as to decrease the material viscosity to a flowable form, applying the liquefied phase change material directly onto the mating surface of the heat dissipating device either by directly dispensing the material, screen printing or stencil printing and cooling the material causing it to cure on the surface of the heat dissipating device.

摘要： A method of manufacturing a heat pipe construction includes first providing a tubular pipe with an open end. A thermally conductive material, such as a metallic material or a filled polymer composite material is overmolded over or cast around the tubular pipe. Additional heat dissipating elements, such as insert molded pins, may be provided in the overmolded or cast material to enhance thermal conductivity of the heat sink assembly. The tubular pipe is then filled with heat pipe media, such as water or ammonia, and then immediately sealed therein to effectively form an embedded heat pipe within a thermally conductive cast or overmolded structure. With the method of the present invention, an heat pipes can be overmolded with or cast into other heat dissipating material structure to improve overall performance of the heat pipe without damaging the heat pipe.

摘要： A net-shape molded elastomeric gasket for dissipating heat and providing electro-magnetic interference (EMI) shielding for an electronic device is formed by loading a base elastomeric matrix material with thermally conductive filler and EMI reflective metallic filler and injecting the mixture into a mold cavity. The gasket of the present invention provides superior sealing between the case sections of an electronic device by shielding the device from EMI infiltration along the seam between the sections. In addition, the gasket of the present invention is in thermal communication with the case sections of the electronic device to provide thermal transfer and dissipation between the separate parts of the device.

摘要： The present invention provides a novel visible light curable composition for forming a thermally conductive interface and a method of using the same. The composition is used to promote the transfer of heat from a source of heat such as an electronic device to a heat dissipation device such as a heat sink. The composition includes an elastomeric base matrix containing a light curable catalyst, loaded with a thermally conductive filler material such as boron nitride grains or ceramic filler. After the compound is prepared, it is screen or stencil printed onto the desired surface and cured by exposure to visible light. The present invention provides a thermal interface that is bonded to the surface of the desired surface and has sufficient compressibility to allow it to overcome the voids in the mating surface to which the assembly is mounted.
