In the present invention, on the basis of a relative positional relationship with respect to an electrode corresponding to solder on a substrate, a target fitting position of a component, and a correction value for the target fitting position, the orientation of positional displacement with respect to the electrode corresponding to the solder and the orientation of the correction of the target fitting position according to the correction value are simultaneously displayed on a display device. It is determined, for a component in which a fitting defect has occurred after component fitting, whether the cause of the fitting defect is in the process for detecting the position of the solder, the process for calculating the correction value, or the process for fitting the component. |
