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.
