ELECTRICAL-CIRCUIT MANUFACTURING ASSISTANCE DEVICE AND ELECTRICAL-CIRCUIT MANUFACTURING ASSISTANCE METHOD

摘要

The present invention efficiently provides quality-related assistance for the manufacture of electrical circuits by means of an electrical-circuit manufacturing line. On the basis of processing-device-related information that includes information on operations performed on substrates by a substrate-processing device and/or information on actions performed on said substrate-processing device, a change in substrate processing conditions is recognized (154); work locations in which said change could affect work quality are identified and at least one of said work locations is selected to monitor (156); and a determination is made regarding change in work quality at said location(s) (158). Said determination is made by comparing the following: comparison data regarding circuit boards processed before the abovementioned change in substrate processing conditions; and comparison data regarding circuit boards processed after said change. Said comparison data includes at least one of the following: operation-dependent data acquired so as to depend on the operations performed by the abovementioned substrate-processing device; and inspection data from an inspection device that inspects work results.
