Abstract: A conveying apparatus used for conveying an object is provided. The conveying apparatus includes a first conveying unit, a second conveying unit, and a supporting unit. An object leans against the first conveying unit and the second conveying unit and moves from the first conveying unit toward the second conveying unit along a conveying path. The supporting unit is configured between the first conveying unit and the second conveying unit to support and guide the object.

Abstract: The disclosed is a thermal interface layer disposed between a heat-generating apparatus and a thermal dissipation component. The thermal interface layer is composed of a mixture of a resin matrix and highly thermal conductive powders, wherein the resin matrix is obtained by reacting epoxy resin, diisocyanate, and amino curing agent. Tuning the ratio of the diisocyanate and the epoxy resin may modify the hardness and the viscosity of the thermal interface material. After repeated tested at high temperature for long period, the described thermal interface layer still remained viscose, soft, and thermally resistant. The filling effect of the thermal interface material in the voids between the electronic device and the sink is largely improved. The thermoplastic thermal interface material may fill the void or cavity on the surface of the electronic apparatus, thereby improving the heat spreading efficiency of the whole structure.
