Portable telephone
View Patent ↗A portable telephone including an integrated circuit chip module with a first integrated circuit chip including a first power source pad for a first power voltage and an adjacent second power source pad for a second power voltage, the first power voltage being higher than the second power voltage, a second integrated circuit chip including a third power source pad for the first power voltage and an adjacent fourth power source pad for the second power voltage, and a wiring board including a first power source wire electrically connected to the first power source pad, a second power source wire electrically connected to the second power source pad, a third power source wire electrically connected to the third power source pad, and a fourth power source wire electrically connected to the fourth power source pad. Distance between the first and second power source wires is shorter than distance between the first or second power source wires and the third or fourth power source wires, and distance between the third and fourth power source wires is shorter than distance between the first or second power source wires and the third or fourth power source wires.
1. A portable telephone including:
an integrated circuit chip module comprising:
a first integrated circuit chip including a first power source pad for a first power voltage and a second power source pad for a second power voltage, the first and second power source pads being adjacent to each other, the first power voltage being higher than the second power voltage,
a second integrated circuit chip including a third power source pad for the first power voltage and a fourth power source pad for the second power voltage, the third and fourth power source pads being adjacent to each other, and
a wiring board including a first power source wire electrically connected to the first power source pad, a second power source wire electrically connected to the second power source pad, a third power source wire electrically connected to the third power source pad, and a fourth power source wire electrically connected to the fourth power source pad, wherein
a distance between the first and second power source wires is shorter than a distance between the first or second power source wires and the third or fourth power source wires, and
a distance between the third and fourth power source wires is shorter than a distance between the first or second power source wires and the third or fourth power source wires.
2. The portable telephone according to claim 1 , wherein, a distance between a set including the first and second power source wires and a set including the third and fourth power source wires is at least twice the distance between the first and second power source wires.
3. The portable telephone according to claim 1 , wherein the wiring board is a flexible wiring board.
4. The portable telephone according to claim 1 , wherein, the first integrated circuit chip and the second integrated circuit chip are flip-chip mounted on the wiring board.
5. The portable telephone according to claim 1 , including a circuit signal processing an image signal.
6. The portable telephone according to claim 1 , including an image pick-up device.
7. The portable telephone according to claim 6 , including a transmitter and a receiver.
8. The portable telephone according to claim 6 , transmitting in real time a moving picture picked up by the image pick-up device while emitting a wave.
