Abstract
A wire bonding apparatus includes: a first tensioner which forms, nearer a wire supply side than a bonding tool, a first gas flow for applying a tension toward the wire supply side on a wire; a second tensioner which forms, between the first tensioner and a pressing part of the bonding tool, a second gas flow for applying a tension toward the wire supply side on the wire; and a control part which controls the first tensioner and the second tensioner. The control part implements control, in a predetermined period after a first bonding step for bonding the wire to a first bonding point, to turn off at least the second gas flow of the second tensioner among the first tensioner and the second tensioner or to make at least the second gas flow smaller than in the first bonding step.
