Patent ID: 8601429

Claim:
A method for determining flip chip connections, comprising: using at least one computing system having at least one processor to perform a process, the process comprising: generating a first projection having representations of bumps arranged over a core of the flip chip by at least drawing a line or a line segment through a bump between a location within a first ring of a flip chip and an outer portion of the flip chip, wherein the representations of the first projection comprise at least one representation of the first ring and at least one representation of a second ring, and the first ring is an inner ring to and is different from the second ring; generating a second projection having representations of fixed I/O pads arranged around the core; and determining connections between bumps and fixed I/O pads based at least in part on representations of respective first and second projections so that no bump—fixed I/O pad connection crosses another bump—fixed I/O pad connection.
