Patent number: 11961819Abstract: A wire bonding apparatus connecting a lead of a mounted member with an electrode of a semiconductor die through a wire comprises a capillary through which the wire is inserted, a shape acquisition part which acquires the shape of the lead to which the wire is connected, a calculating part which calculates an extending direction of a wire tail extending from the end of the capillary based on the shape of a lead to which the wire is connected next, and a cutting part which moves the capillary in the extending direction and cuts the wire to form the wire tail after the lead is connected with the electrode through the wire. Thus, in the wire bonding using wedge bonding, joining part tails (183a, 283a, 383a) formed in continuation to a first bonding point can be prevented from coming into contact with each other.Type: GrantFiled: March 4, 2020Date of Patent: April 16, 2024Assignee: SHINKAWA LTD.Inventors: Naoki Sekine, Yasuo Nagashima
