ABSTRACT:
An inspecting apparatus is arranged on an electronic component mounting line for inspecting whether a mounting state of the component mounted by a mounting apparatus in a precedent process or a printing state of a cream solder by a cream solder printing apparatus in a precedent process is non-defective or defective. The inspecting apparatus includes an input device for taking data of the mounting state of the component to be inspected or the printing state of the cream solder to be inspected, a comparing device for comparing the data of the mounting state or the printing state input through the input device with an absolute decision criterion having a predetermined allowable range to decide whether the mounting state or the printing state is non-defective or defective and an operating state criterion which is within and narrower than the allowable range of the absolute decision criterion and a deciding device for deciding an operating state of the mounting apparatus or the cream solder printing apparatus in the precedent process based the data which is both within the absolute decision criterion and outside the operating state criterion.
