Abstract:
1. A component mounting method for mounting a component having a plurality of bump electrodes on one face thereof onto leads of a mounting object, comprising: holding with a mounting head a rear face of the component, the rear face being opposite to the face having the bump electrodes; aligning the component with the mounting object disposed on a supporting base, and contacting the individual bump electrodes of the component to the individual leads of the mounting object; and applying a pressure load and thermal energy to the rear face of the component while providing ultrasonic vibration, a vibrating direction of which is substantially parallel to the rear face, the thermal energy being applied to the rear face of the component by a heater provided in the mounting head; and wherein the rear face of the component is held by a working face of an oscillator that is configured such that vibration provided to an end face thereof causes vibration substantially parallel to the working face and such that a node of an oscillation mode is formed on an axis perpendicular to the working face; wherein the oscillator forms part of the mounting head; and wherein the pressure load is applied to the node of the oscillator.
