<p><P>PROBLEM TO BE SOLVED: To provide an apparatus and method for measurement of mounting accuracy of a mounting device, capable of measuring the driving accuracy of a mounting head and an imaging camera, and capable of mounting electronic components precisely based on the measuring results. <P>SOLUTION: A control unit 12 includes: a function to drive a mounting head along a predetermined direction on the lateral side of the reference mark of a measuring substrate, and to form dent marks at the same intervals as the reference mark; a function to sequentially drive a substrate camera along a predetermined direction so that the center of an optical axis may coincide with a coordinate that the reference mark has set in advance, and to take a picture of the reference mark and the dent mark located in a position that corresponds with the reference mark; and a function to obtain deviation between the coordinate of the reference mark and the center of the optical axis of the imaging camera based on the imaging of the substrate camera, to compute the transfer precision of the imaging camera based on the deviation between the coordinate of the reference mark and the center of the optical axis of the imaging camera, and to compute the transfer precision of the mounting head based on the computed transfer precision of the substrate camera and the coordinate of the dent mark. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
