Mounting method of ic chip and manufacturing method of head suspension assembly with the ic chip.

摘要

A method of mounting an IC chip on a suspension having connection pads. The IC chip has a circuit for a thin-film magnetic head element and connection terminals connected to the circuit. The method includes a step of increasing a load applied to the IC chip so that metal bumps formed on the connection terminals press the connection pads formed on the suspension, respectively, and a step of starting application of the ultrasonic vibration to the IC chip during the increasing of the load applied to the IC chip.
