Abstract:
A component bonder for press-bonding a component onto a contacting surface by applying load and vibration to the component,said bonder comprising a bonding tool and a pressing mechanism for pressing said bonding tool onto the component, said bonding tool comprising: a lateral horn supported by a fixing part; a transducer arranged to apply vibration to said horn in a first direction which is a length direction of said horn; a protrusion protruding from said horn in a second direction approximately perpendicular to said first direction; and a bonding portion provided on a tip of said protrusion and arranged to contact the component, wherein a phase of expansion and compression vibration waveform of said horn in the second direction, which is generated by said vibration, is set to the same phase as that of bending vibration waveform at said protrusion generated by said vibration.
