Abstract:
1. A manufacturing method of a chip package structure, comprising: providing a circuit substrate, the circuit substrate has a first surface, a second surface and a through hole connecting to the first surface and the second surface; providing a chip, the chip has an active surface and a plurality of bonding pads, wherein the bonding pads are disposed on the active surface; fixing the chip on the circuit substrate, wherein the second surface of the circuit substrate and the active surface of the chip are opposite to each other, and the through hole exposes the bonding pads; forming a plurality of bonding wires passing through the through hole, and the bonding pads are electrically connected to the first surface of the circuit substrate through the bonding wires; sticking a flexible film on the first surface of the circuit substrate, wherein the flexible film has an opening, and the opening exposes the bonding wires, the bonding pads, the through hole and a part of the first surface; forming an encapsulant in the opening and the through hole to cover a part of the active surface, the bonding wires and a part of the first surface; and removing the film.
