    摘要: An integrated circuit package with a fully-exposed heat sink is provided. The integrated circuit package includes a substrate having a first side being formed with first conductive traces and a second side being formed with second conductive traces. At least one chip is mounted on the substrate and electrically connected to the first conductive traces. A plurality of solder balls are provided at the terminal ends of the second conductive traces to allow external connection of the chip. The fully-exposed heat sink is mounted on the substrate. The heat sink is formed with a plurality of supportive legs arranged in such a manner as to allow a bottom surface of the heat sink to be separated from the chip and a top surface of the heat sink to be tightly attached to a cavity in a mold used to form an encapsulant for enclosing the chip. A plurality of positioning tongues are formed on the heat sink for securing the heat sink in position when performing a molding process for forming the encapsulant. With this integrated circuit package, no jig is required in the assembly of the integrated circuit package. Moreover, since there is no need to use adhesives to adhere the supportive legs onto the substrate, the integrated circuit package would not suffer from delamination as in the case of the prior art. The fully-exposed heat sink allows an increased heat-dissipating efficient as compared to the prior art.

    摘要: An externally-embedded heat-dissipating device is designed for use with a BGA (Ball Grid Array) IC package for dissipating the IC-produced heat during operation to the atmosphere. that can help further increase the efficiency of heat dissipation from the BGA IC package. The heat-dissipating device is characterized in that it can be externally embedded in the top surface of the encapsulant without having to be supported on the substrate, and also in that it can help reduce the heat path from the IC chip to the heat-dissipating device so that heat-dissipation efficiency can be further increased as compared to the prior art. Further, the heat-dissipating device can help reduce manufacture cycle time and cost and also help prevent delamination, flash, and popcorn effect that would otherwise occur in the case of the prior art. It also can help save layout space over the substrate for compact design of the package. Overall speaking, the proposed heat-dissipating device is more advantageous to use than the prior art.

    摘要: A heat dissipation unit and a semiconductor package having the same are disclosed. The semiconductor package includes a carrier; an electronic component mounted on and electrically connected to the carrier; a heat dissipation unit, which includes a flat section attached to the electronic component, extension sections connected to the flat section, and a heat dissipation section connected to the extension sections; and an encapsulant encapsulating the electronic component and the heat dissipation unit, wherein stress releasing sections are at least disposed at intersectional corners between the extension sections and the flat section so as to prevent projections from being formed by concentrated stresses in a punching process of the heat dissipation unit, thereby maintaining flatness of the flat section and further preventing circuits of the electronic component from being damaged due to a contact point produced between the electronic component and the flat section in a molding process.
