A quality control apparatus is provided with: non-uniformity calculation means, which calculates non-uniformity of feature values related to positions or shapes that should be the same in different parts of an electronic component or bonding locations between an electronic component and a printed circuit board; assessment means, which assesses whether or not the non-uniformity is greater than or equal to a predetermined threshold; and parameter modification means which, if the non-uniformity is greater than or equal to the predetermined threshold, proposes a modification to a user regarding modifying a setting parameter for a solder printing apparatus or a mounter. For the non-uniformity, it is possible to adopt such a value as a difference or ratio between maximum values and minimum values for feature values which should normally be the same in different parts; for example, the non-uniformity can be with respect to such values as heights of electrodes or terminals, or solder lengths or solder angles. |
