PURPOSE: To inspect the quality of soldering by an online system, providing a judge means constituted so that stored proper image data is compared with the image data of a connected part successively subjected to connection treatment to judge the connection state of the connected part.
CONSTITUTION: Proper image data is preliminarily stored in a proper image data memory part 13 and compared with the image data of a soldered part successively subjected to soldering treatment in a connection state judge part 14 and the quality of soldering is automatically judged on the basis of the difference between the number of picture elements at the soldered part in these image data. The soldered part after the completion of soldering is displayed on a CRT display apparatus 15 by ITV2. The difference between the number of picture elements at the soldered part, that is, the number of picture elements at a Q-part are calculated by operation. If the number of the picture elements are equal to or more than a predetermined value, the connection state judge part 14 judges that the soldered part is inferior. By this method, the judgement of soldering quality can be certainly judged regardless of the individual difference of a soldering inspecting and judging person.
