Title: Wire bonding method
Inventor: ARITA KIYOSHI
IPC: H01L21/60
Filed: 1999-04-05
Abstract: PROBLEM TO BE SOLVED: To provide a wire bonder capable of wire-bonding, without causing damages to a semiconductor device due to accumulated charges on existing mounted components. SOLUTION: A wire bonder for electrically connecting external connecting electrodes of an electronic component mounted on a substrate to circuit electrodes on a board through wires has a cut clamper 16 for clamping a wire 15 which is fed from a spool 14, inserted through a capillary tool and bonded. The clamper 16 is electrically conducted to a ground 21. Since this makes the potential of the wire 15 equal to the ground potential in bonding, charges accumulated on existing mounted components such as chip capacitors are discharged, thereby avoiding breakages of electronic components during wire bonding.
