Patent ID: 7884482

Claim:
A flip-chip mounting substrate comprising: an insulating layer or a solder resist; a plurality of first wiring patterns each including: a first bonding pad exposed from the insulating layer or the solder resist; and a first lead wire continuously extending from the first bonding pad, the first lead wire having first predetermined parts exposed from the insulating layer or the solder resist; and a plurality of second wiring patterns each including: a second boding pad exposed from the insulating layer or the solder resist; and a second lead wire continuously extending from the second bonding pad, the second lead wire having second predetermined parts exposed from the insulating layer or the solder resist, wherein a geometric shape of each of the first bonding pads is different from that of each of the second bonding pads, while a planar area of each of the first bonding pads is equal to that of each of the second bonding pads, and wherein a geometric shape of each of the first predetermined parts in a plan view is different from that of each of the second predetermined parts, while a planar area of each of the first predetermined parts is equal to that of each of the second predetermined parts.
