ABSTRACT:
An ultrasonic wire bonding method that uses an ultrasonic oscillation output from a non-rotatable form, wherein the ultrasonic oscillation output used for bonding the leads that extend in an X-direction which is perpendicular to the axial direction of a horn is set to be larger than the ultrasonic oscillation output used for bonding the leads extending in a Y-direction which coincides with the axial direction of the horn.
