Abstract:
1. A package structure for preventing gold bonding wires from collapsing, which is especially useful for those chips whose bonding pads are on the chip center to be packaged on a BGA substrate, the package structure comprising: a BGA substrate; a BGA chip whose bottom is connected to the BGA substrate by an insulating sealant, and the BGA chip having at least two arrays of bonding pads; two dummy dies connecting to an upper surface of the chip, the upper surface of the dummy dies having redistribution layers which corresponds to the bonding pads; two first gold bonding wires respectively connecting from the bonding pads in a first and a second arrays to one end of the redistribution layers of the two dummy dies, and the redistribution layers having the other end connecting to gold fingers on the upper surface of the BGA substrate by two second gold bonding wires.
