Abstract:
1. A method of mounting an electronic part, comprising: picking up the electronic part placed on a table by a pick-up nozzle; delivering the electronic part from the pick-up nozzle holding the electronic part to a mounting nozzle; comparing a position of the electronic part held by the mounting nozzle and a position on a circuit substrate where the electronic part is mounted, to thereby correct the mounting position where the electronic part is mounted by the mounting nozzle, including detecting displacements of the electronic part held by the pick-up nozzle with respect to a reference position, the displacements being obtained in the form of displacements in X- and Y-directions perpendicular to each other and an angle θ of rotation; mounting the electronic part onto the circuit substrate by the mounting nozzle, and when delivering the electronic part to the mounting nozzle, correcting the displacements in the X- and Y-directions and the angle θ of rotation to carry out a control such that the electronic part has a predetermined attitude with respect to the mounting nozzle.
