Abstract:
A method for mounting an electronic component by connecting an electrode of the electronic component to a wiring electrode of a substrate via a bump so as to mount the electronic component on the substrate, comprising the steps of:disposing a contact portion of an ultrasonic-wave applying member in contact with the electronic component; positioning the electronic component on the wiring electrode of the substrate via the bump; applying ultrasonic oscillation to the electronic component under a condition in which the oscillating amplitude of the contact portion of the ultrasonic-wave applying member is larger than the oscillating amplitude of the electronic component, and the oscillating amplitude of the electronic component is 0.20 &mgr;m or larger so as to metallically bond the bump and the electrode of the electronic component or the bump and the wiring electrode on the substrate to thereby mount the electronic component on the substrate via the bump.
