ABSTRACT:
An assembly line includes a printing device for printing solder on a land of a circuit board, a mounting device for mounting an electric component at a predetermined position of the solder, and a soldering device for soldering the land to a terminal of the component. A monitored items detecting device detects predetermined to be monitored items of the board and equipment used in the printing, mounting, or soldering devices, and a control device analyzes a condition of the equipment and quality of the board with reference to warning criterion which do not exceed failure criterion, and then dynamically controls the various devices accordingly.
