Abstract:
A capillary holding structure in combination with an ultrasonic horn used in a wire bonding apparatus in which a capillary is held in a capillary attachment hole formed in a tip end of said ultrasonic horn so that a wire passing through said capillary is connected to a plurality of bonding points, said holding structure comprising a perpendicular slit formed on an opposite side of said capillary attachment hole from said tip end of said ultrasonic horn and extending from said attachment hole in a direction away from said tip end, a portion completely surrounding said capillary attachment hole adjacent said tip end through which said perpendicular slit does not extend said portion being decreased in thickness so as to form a thin part relief means on said capillary attachment hole, and a bolt inserted into a bolt insertion hole formed so as to cross said perpendicular slit for tightening said perpendicular slit.
