  • Patent number: 9735091
    Abstract: The invention discloses a package structure for better heat-dissipation or EMI performance. A first conductive element and a second conductive element are both disposed between the top lead frame and the bottom lead frame. The first terminal of the first conductive element is electrically connected to the bottom lead frame, and the second terminal of the first conductive element is electrically connected to the top lead frame. The third terminal of the second conductive element is electrically connected to the bottom lead frame, and the fourth terminal of the second conductive element is electrically connected to the top lead frame. In one embodiment, a heat dissipation device is disposed on the top lead frame. In one embodiment, the molding compound is provided such that the outer leads of the top lead frame are exposed outside the molding compound.

  • Patent number: 9484290
    Abstract: A composite substrate made of a conductive pattern structure mounted on a lead frame is used for an electronic system package. High heat generated electronic components are adapted to mount on the lead frame and relatively low heat generated electronic components are adapted to mount on the conductive pattern structure. Metal lines are used for electrical coupling between the circuitry of the IC chip and the conductive pattern structure. An electronic system with the composite substrate gains both advantages—good circuitry arrangement capability from the conductive pattern structure and good heat distribution from the lead frame.

  • Patent number: 8269330
    Abstract: A MOSFET pair with a stack capacitor is disclosed herein. It can regulate the input voltage and optimize a short EMI loop. It has a bottom lead frame and an up lead frame, which can simultaneously dissipate the heat generated by two MOSFETs to achieve excellent thermal-dissipation. It can adopt solder, Ag epoxy, or gold balls to implement the electrical bonding of two MOSFETs with the bottom lead frame and the up lead frame to achieve excellent structural flexibility. A device, such as an IGBT, a diode, an inductor, a choke, and a heat sink, can be stacked above the up lead frame to form a powerful SiP module. A corresponding method of manufacturing the MOSFET pair with a stack capacitor is also disclosed herein, which is simple, time-saving, flexible, cost-effective, and facile.
