PROBLEM TO BE SOLVED: To determine the possibility of a defect even in the case that a product has part floating with little floating amount or the wettability of a part electrode a little worse than that of a good part.SOLUTION: A defect determination device 100 includes: solder printing means 10 for printing solder on a substrate; part mounting means 11 for mounting a part on the solder-printed substrate; mounted part position measuring means 12 for measuring part coordinates after the part is mounted, and for calculating a first coordinate deviation from part implementation target coordinates; reflow means 13 for heating the substrate after the part is mounted and for soldering the part; after-reflow part position measuring means 14 for measuring part coordinates after reflow and for calculating a second coordinate deviation from the part implementation target coordinates; and fault determination means 15 for determining the possibility of a defect of the part after reflow on the basis of the first coordinate deviation and second coordinate deviation. |
