  • Publication number: 20220380547
    Abstract: A thermal interface material delivered as a single-component precursor mixture which reacts to form a soft, solid material. Thermally conductive particles are dispersed in the reactive polymer matrix resulting in a composite material with high thermal conductivity. A reaction inhibitor is provided so that the one-component system is stable in storage and handling at room temperature, and curable at an elevated temperature. The uncured precursor material is easily dispensed using conventional single-component automated pumping equipment, and subsequently cured in place.

  • Patent number: 8430264
    Abstract: A package for delivery of a tacky product includes a carrier with a plurality of cavities separately disposed along a length and width thereof. Each of the cavities in the carrier tape includes a base that is sized to operably receive and support the product within the cavity. The base of each cavity includes a surface profile which defines a contact surface area that is sufficiently low so as to facilitate removal of the product from the cavity without damage to the product. In some cases, the contact surface area is less than about 50% of a base surface area of the base. The carrier may be configured to stack with other carriers without risk of damage to the tacky product.

  • Patent number: 6984685
    Abstract: A stabilized thermally conductive mechanical compliant laminate pad to be interposed between opposed surfaces of a generating semi-conductor device and a heat sink, with the laminate pad comprising upper and lower laminae on opposed surfaces of a central stabilizing apertured grid. The laminae are subjected to a compressive force at an elevated temperature until portions of the laminae extend through the apertures to form a continuum. The laminae comprise a polymer matrix having a quantity of a low melting indium or gallium alloy and a thermally conductive particulate dispersed there through, with the polymer matrix being a hot wax or melt resin. With the upper and lower laminae positioned on opposed surfaces of a central stabilizing apertured grid a compressive load is applied to force portions of said laminae to pass through apertures in the mesh grid to form a continuum.
