Patent ID: 6931717

Claim:
An apparatus for mounting an electronic part onto a circuit substrate, the apparatus comprising: a table for placing and holding the electronic part, the table being movable in X- and Y-directions perpendicular to each other; a pick-up nozzle for picking up the electronic part placed on the table, the pick-up nozzle being movable in the X-direction; displacement amount detection means for capturing an image of the electronic part held by the pick-up nozzle to detect displacements of the electronic part with respect to a reference attitude, the displacements being obtained in the form of displacements in the X- and Y-directions perpendicular to each other and an angle θ; a mounting nozzle for mounting the electronic part onto the circuit substrate, to which the electronic part is delivered from the pick-up nozzle, and which is movable in the Y-direction and is capable of being rotated with an axis perpendicular to each of the X- and Y-directions as a center; and a substrate stage for holding the circuit substrate, wherein when the electronic part is delivered from the pick-up nozzle to the mounting nozzle, the displacements in the X-direction, the Y-direction and the angle θ are corrected to carry out a control such that the electronic part has a predetermined attitude with respect to the mounting nozzle.
