PURPOSE:To control the bend of a loop, by pressing down a tool, putting a wire between the tool and a bonding part, rolling the wire and twisting it. CONSTITUTION:A wire 6 is put between an external lead terminal 9 and the bottom side of a capillary 22 by pressing the capillary 22, and is rolled in the direction of an arrow B on the terminal 9 by transferring the capillary 22. One end of a loop 21 is twisted, and its curl is eliminated. Thus a loop 23 is obtained, bend control of which is finished. Then a second supersonic thermal compression bonding is applied, and the wire is cut. By this constitution, defects due to loop contact can be avoided. |
