Abstract:
1. A package structure, comprising: a circuit substrate, having a first surface, a second surface opposite to the first surface, a plurality of side surfaces connected between the first surface and the second surface, and a plurality of contacts disposed on the first surface; at least a chip, disposed on the second surface of the circuit substrate and electrically connected to the circuit substrate; a plurality of leads, disposed on the periphery of the second surface of the circuit substrate to surround the chip, wherein each of the leads has an inner lead portion and an outer lead portion, and each lead is electrically connected to the circuit substrate via the inner lead portion thereof; an encapsulant, encapsulating the circuit substrate, the chip and the inner lead portion of each lead and exposing the first surface of the circuit substrate and the outer lead portion of each lead, wherein an upper surface of the encapsulant and the first surface of the circuit substrate are coplanar with each other; and a heatsink, embedded inside the encapsulant and contacting the inner lead portions of the leads, wherein the heatsink has a frame shape and surrounds the circuit substrate, an end of the heatsink is attached to the inner lead portion of each of the plurality of leads, and another end of the heatsink is leant against the side surfaces of the circuit substrate.
