  • Patent number: 8207601
    Abstract: An electronic component includes a lead frame assembly, an insert, a semiconductor chip and an encapsulation compound. The lead frame assembly includes a mounting hole, a die pad, a plurality of bonding fingers and a plurality of lead fingers. The insert includes a hollow center and is provided at the mounting hole of the lead frame assembly. The semiconductor chip is arranged on the die pad and includes contact areas on its surface. A plurality of electrical contacts respectively links the contact areas of the semiconductor chip to the bonding fingers of the lead frame assembly. An encapsulating compound encloses the insert, the semiconductor chip, and the electrical contacts, however, leaves the hollow center of the insert uncovered.
