  • Publication number: 20250022770
    Abstract: A power module structure is provided. The power module structure includes a substrate, a copper layer, a metal layer, and a chip. The copper layer is disposed on the substrate. The metal layer is disposed on the copper layer. The area of the metal layer is smaller than that of the copper layer. The chip is disposed on the metal layer. The area of the chip is smaller than that of the metal layer.

  • 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: 9848518
    Abstract: An integrated power module packaging structure includes a plastic housing having a cavity; a plurality of step-shaped pins embedded in the plastic housing, a first printed circuit board disposed in the cavity, and a second printed circuit board disposed above the first printed circuit board in the cavity. Each of the step-shaped pins includes a first L-shaped bending portion and a second L-shaped bending portion connected to each other. The first printed circuit board is disposed with at least a power device and is electrically connected to at least a part of the first L-shaped bending portions. Two opposite surfaces of the second printed circuit board are respectively disposed with at least an electronic device, and the second printed circuit board is electrically connected to at least a part of the second L-shaped bending portions.
