PROBLEM TO BE SOLVED: To shorten inspection time by reducing losses in an inspection cycle time. SOLUTION: Part packaging coordinate data are sorted into groups having a same level of warpages according to the warpage data of the substrates registered (step S201) in advance. Next, the distances between each point and the other points in the groups are calculated, and two points having the shortest distance therebetween are selected (step S203) and are joined to each other. This step is repeated, in the order of increasing distance, to form a chain (step S204). Then the distances from each chain to respective chains are determined (step S205), and each chain is joined (step S206) to a single chain in the order of increasing distance, to form a single chain. |
