Patent ID: 8678266

Claim:
A method of bonding a first bond point to a second bond point with a wire per bonding cycle, utilizing a wire bonding apparatus, the method comprising: a first bonding step; an examination and re-bonding step; a looping step; and a second bonding step; wherein the method to continuously perform a cycle of bonding steps of: the first bonding step of, before the examination and re-bonding step, bonding a ball formed at a tip end of a capillary to the first bond point by causing the capillary to descend, thereby forming a first bonding part to the first bond point; the examination and re-bonding step of, between after the first bonding step and before the looping step, examining whether the first bonding part is bonded to the first bond point while ascending the capillary to a reverse starting point when the first bonding part fails to be bonded thereto, re-bonding the non-bonded first bonding part formed at the tip end of the capillary to the first bond point by causing the capillary to descend or when the first bonding part has been completed thereto, no re-bonding to the first bonding point; the looping step of, between after the examination and re-bonding step and before the second bonding step, causing the capillary to move horizontally as far as a bend formation point in a direction opposite from the second bond point, then causing the capillary to ascend as far as a loop top point while paying out the wire, and then causing the capillary to move to directly above the second bond point; and the second bonding step of, after the looping step, bonding the wire to the second bond point while causing the capillary to descend thereto, thereby forming a second bonding part on the second bond point, thus connecting the first bond point and the second bond point with wire without stopping the wire bonding apparatus executing each of bonding steps.
