    摘要: A chip package structure includes a lead frame having first and second patterned metal layers and an insulation layer, a chip, and an encapsulant covering the first patterned metal layer and the chip. The first patterned metal layer includes a chip pad with first recesses and bonding pads in the first recesses. A first groove exists between each bonding pad and the chip pad. The second patterned metal layer connecting the first patterned metal layer includes terminal pads and a heat dissipation block thermally coupled to the chip pad. The heat dissipation block includes second recesses where the terminal pads are located and electrically connected to the corresponding bonding pads. A second groove exists between each terminal pad and the heat dissipation block. The insulation layer is located between the bonding pads and the terminal pads. The chip on the chip pad is electrically connected to the bonding pads.
