  • Patent number: 10806046
    Abstract: A package structure of a power module is provided. The package structure includes a body having a sidewall, a first protruding structure protruding outward from one end of the sidewall, a second protruding structure protruding outward from another end of the sidewall and opposite to the first protruding structure, and a spring having two ends embedded in the first and the second protruding structures, respectively. The stress is transferred to the first and the second protruding structures via the spring, respectively. The equivalent stiffness of the spring is different from that of the body so that the package structure as a whole suffers the stress uniformly.

  • Patent number: 9999145
    Abstract: A power module having a packaging structure includes a substrate having a first conductive area, a second conductive area, a third conductive area, a first fixing area and a second fixing area. The first, the second and the third conductive areas are electrically connected to a first terminal, a second terminal and a third terminal, and the first and the second fixing areas are electrically connected to a first switch set and a second switch set, so that they are in a parallel arrangement. The first terminal is a current input end, the second terminal is an intermediate end, and the third terminal is a current output end. When a current flows from the current input end to the intermediate end, or from the intermediate end to the current output end, the current flows straightly in order to reduce a crossover area and lower the stray inductance.

  • Patent number: 7528472
    Abstract: A chip package mechanism. A substrate is disposed in a receiving chamber of a base. A chip is disposed on a target surface of the substrate. A plurality of supporting elements is disposed on the target surface and surrounds the chip. A gap for receiving the chip is created in the receiving chamber and between the target surface and the base by means of the supporting elements. A barricade is disposed in the gap to separate glue filled in the receiving chamber from contacting the chip. Outside water and particles cannot enter the chip package mechanism. The chip thus has a prolonged lifespan after packaged in the chip package mechanism.
