Abstract:
1. A bonding method for a bonding apparatus for bonding a wire between a first bonding point and a second bonding point, comprising the steps of: preparing an electrical non-bonding detection step for electrically detecting non-bonding between the first bonding point and the wire by processing electrical conduction state signals acquired by said electrical conduction state acquisition device and indicative of electrical conduction state between the first bonding point and the wire; an optical non-bonding detection step for optically detecting non-bonding between the first bonding point and the wire by processing images acquired by said imaging device; a data acquisition step for acquiring, from said memory unit, data on whether the first bonding point is a predetermined bonding point on which said electrical non-bonding detection step is not applicable; and a non-bonding verification step for verifying non-bonding of the first bonding point using said optical non-bonding detection step when the first bonding point is said predetermined bonding point that is determined, based upon data acquired in said data acquisition step.
