Abstract:
1. A method of fabricating an electric circuit, comprising a first working process of performing a predetermined first working operation on a circuit substrate, and a second working process of performing a predetermined second working operation on said circuit substrate after the first working operation, wherein an improvement comprises: said first working process including a first substrate-identifying step of obtaining substrate identifying information identifying said circuit substrate on which said predetermined first working operation is to be performed, a specific-information obtaining step of recognizing a specific-information providing portion of said circuit substrate, to obtain specific information indicating at least one specific characteristic of said circuit substrate, a first working step of performing said predetermined first working operation on the basis of the obtained specific information, and a specific-information storing step of storing said specific information in relation to said substrate identifying information; and said second working process including a second substrate-identifying step of obtaining said substrate identifying information identifying said circuit substrate on which said predetermined second working operation is to be performed, and a second working step of performing said predetermined second working operation on the basis of said specific information stored in relation to said substrate identifying information.
