  • Patent number: 10804181
    Abstract: Embodiments of the present invention relate to an heterogenous thermal interface material (TIM). The heterogenous TIM includes two or more different materials. One material has a low elastic modulus, also known as Young's modulus, and is utilized primarily to transfer heat from one component to another component. Another material has a higher elastic modulus and is primarily utilized to bond or connect the corners and/or edges of one component to the other component. The high elastic modulus material is generally located within the heterogenous TIM where TIM strain is or is expected to be high. For example, the high elastic modulus material may be located at the corner and/or edge regions of the heterogenous TIM.

  • Patent number: 9054074
    Abstract: A series of hierarchical channels are formed in a first member surface of a first member using a continuous-feed manufacturing process. The channels are configured to control particle stacking. The first member is pressed to a second member with a layer of particle-filled viscous material between the first member surface and a second member surface of the second member. An inventive assembly includes mating surfaces with at least one surface formed with a series of parallel hierarchical channels configured to control stacking of the particles during pressing together of the surfaces.

  • Patent number: 9041192
    Abstract: Flip chip packages are described that include two or more thermal interface materials (TIMs). A die is mounted to a substrate by solder bumps. A first TIM is applied to the die, and has a first thermal resistance. A second TIM is applied to the die and/or the substrate, and has a second thermal resistance that is greater than the first thermal resistance. An open end of a heat spreader lid is mounted to the substrate such that the die is positioned in an enclosure formed by the heat spreader lid and substrate. The first TIM and the second TIM are each in contact with an inner surface of the heat spreader lid. A ring-shaped stiffener may surround the die and be connected between the substrate and heat spreader lid by the second TIM.
