Patent ID: 7030502

Claim:
A flip chip ball grid array (BGA) package with a power ballout assignment of wire bonding packaging comprising: a substrate with a first layout layer and a second layout layer comprising: a first power ring positioned on the first layout layer of the substrate for transmitting a first operating voltage; a second power ring positioned on the first layout layer of the substrate for transmitting a second operating voltage; a plurality of first ballouts arranged to match first operating voltage contacts of a predetermined wire-bonding package circuit board to receive the first operating voltage provided by the circuit board, the first ballouts being positioned on a first conductive block of a the second layout layer of the substrate, the first conductive block being electrically connected to the first power ring through at least a first via; and a plurality of second ballouts arranged to match second operating voltage contacts of the circuit board to receive the second operating voltage provided by the circuit board, the second ballouts being positioned on a second conductive block of the second layout layer of the substrate, the second conductive block being electrically connected to the second power ring through at least a second via; a die comprising: a core circuit for performing a predetermined operation; and at least an input/output circuit (I/O circuit) electrically connected to the core circuit for controlling signals inputted into the core circuit and signals outputted from the core circuit; and a plurality of contacts positioned on the first layout layer, the contacts being electrically connected to the first and second power rings through a third layout layer that lies in between the first and second layout layers; wherein the first power ring and the second power ring are respectively contacted to the core circuit and the I/O circuit of the die; wherein the second power ring is located inside the first power ring; wherein the second ballouts corresponding to the second power ring are disposed inside the first ballouts corresponding to the first power ring.
