A method for manufacturing an electronic device using ultrasonic joining, when the component members of the electronic device includes different structures. The method includes obtaining a joining condition that provides press-down amounts for the materials to be joined at predetermined values. The press-down amount generated by a horn and a supporting member biting into the materials during ultrasonic joining is predetermined for each specific structure of the component member of the electronic device.

Method for manufacturing electronic device

A component-mounting apparatus and a component-positioning unit for positioning a component, having a simple structure with reduced manufacturing cost and a significantly higher component-mounting speed. The component-mounting apparatus includes a holding device that holds a component and moves horizontally and a positioning device having a sloped portion for positioning the component held by the holding device when the component comes into contact with the sloped portion. The positioning device comprises a first rotatable roller member having a sloped side surface with which the component comes into contact; and the horizontal movement speed of the holding device substantially agrees with the horizontal component of the peripheral velocity of the first roller member, with which the component comes into contact.
