PROBLEM TO BE SOLVED: To enable highly reliable wire bonding to a lead part by firmly fixing and holding fine and thin inner leads of several hundreds pins of a lead frame and a TAB for high density mounting in a wire bonding device. SOLUTION: In a wire bonding device, a heater block 6 provided with a magnet and a keep jig such as a window clamper 3 consisting of a magnetic material are used. The keep jig is drawn by magnetic force of a magnet of the heater block 6 and is pressed uniformly against a lead frame 4 without being brought into one-sided contact therewith and wire bonding is carried out. |
