摘要:
An electronic component mounting apparatus includes an electronic component mounting head for holding an electronic component and an up/down device for pressing the electronic component against a circuit board, and the electronic component is pressed against the circuit board while ultrasonic vibrations are applied from an ultrasonic transducer of the electronic component mounting head to the electronic component via a component holding unit, so that the electronic component is mounted onto the circuit board. In the electronic component mounting apparatus, the electronic component is heated via the component holding unit by radiant heat from a heater fixed to the component holding unit in a noncontact state, so that even when the electrothermal heater is replaceably attached, characteristics of the ultrasonic vibrations applied to the electronic component can be maintained constant.
摘要:
There is provided an electronic component mounting apparatus including: a component holder which holds an electronic component; a pressing unit which applies pressure to the held electronic component through the component holder; and an ultrasonic transducer which applies ultrasonic vibration to the held electronic component through the component holder. The component holder includes a horn at one end of which is mounted the ultrasonic transducer and a holding tool which is fixed to the other end of the horn by using bolts and holds the electronic component. The horn has a surface A1 and a surface A2 at the other end and the holding tool has a surface B1 in intimate contact with the surface A1 and a surface B2 in intimate contact with the surface A2.

In a direction parallel to a direction 5 of ultrasonic vibrations imparted from an ultrasonic vibrator 1, the shape of a center portion 3a of a tool 3 and the shape of an end portion 3b of the tool 3 are changed such that the cross-sectional areas are different, whereby ultrasonic amplitudes 9 in a direction perpendicular to the direction 5 of ultrasonic vibrations are substantially equal. By this means, the difference in ultrasonic vibration between at the center portion 3a of the tool 3 and at the end portion 3b of the tool 3 can be eliminated or reduced.

摘要:
In the electronic component mounting apparatus, a vertical load and horizontal loads applied to an electronic component are detected by a load sensor that have piezoelectric elements provided in a stack in the mounting direction of the electronic component. Therefore, the size in the horizontal direction of the load sensor can be reduced, and the load applied to the electronic component can be detected at the neighborhood of the mounting position of the electronic component. Moreover, by comparing a position in a two-dimensional space in which the load values in the X-direction and the Y-direction of the horizontal load are served as coordinate values with a tolerance range in the two-dimensional space, mounting failure can be detected from a deviation in the horizontal loads.
