PURPOSE:To prevent the unsatisfactory open of the electrodes of an element by a method wherein with a conductive paste for electrode connection use printed on element mounting lands, dummy patterns for position recognition use are printed and an element mounting position is recognized by these dummy patterns and the element is mounted in the position. CONSTITUTION:A pair of dummy patterns 6a and 6b for position recognition use, which are used as a reference, and respective lands 2a and 2b are first discriminated and binarized by a binary-coded image discriminating camera. At the time of mounting of an element 4, the element 4 has only to be installed in such a way that the its central part comes to the center position between the patterns 6a and 6b. According to such a way, even if the shift of printing is caused in a pair of conductive patterns and a pair of the dummy patterns, the patterns are simultaneously printed, are shifted by the same amount and the central positions between the patterns are not shifted. Thereby, the element is mounted in the center between a pair of conductive pastes and the unsatisfactory open of electrodes of the element is prevented. |
