Patent ID: 7631795

Claim:
A system comprising: a bonding sequence decision unit receiving wire bonding information, and generating bonding sequence information; a turning point check unit checking whether a capillary of a wire bonder is in contact with a pre-bonded wire, and deciding whether to change the bonding sequence information based on the pre-bonded wire, and creating a first modified bonding sequence information; a bonding simulation unit performing a bonding simulation based on the first modified bonding sequence information, and creating a second modified bonding sequence information based on the bonding simulation, wherein, the turning point check unit includes: a real pad pitch calculation unit calculating a real pad pitch; a first minimum pad pitch calculation unit for calculating a first minimum pad pitch; and a first pad pitch comparison unit comparing the real pad pitch with the first minimum pad pitch, wherein the first minimum pad pitch is defined as the lower limit between a first and second pad of an IC, where a capillary on the second pad does not touch a pre-bonded wire on the first pad, and wherein if the real pad pitch is greater than the first minimum pad pitch, the turning point is not applied, and if the real pad pitch is smaller than the first minimum pad pitch, the first pad pitch comparison unit determines not to apply wire bonding.
