Patent ID: 6885905

Claim:
An electric-circuit fabricating system for fabricating an electric circuit by performing a predetermined working operation on a circuit substrate, comprising: a substrate holding device operable to hold said circuit substrate at a position substantially aligned with a predetermined working position thereof; an imaging device operable to image a surface of the circuit substrate on which the predetermined working operation is to be performed; an imaging control device operable to control said imaging device to take an image of at least one substrate-position fiducial mark provided on said surface of said circuit substrate, and obtain substrate-position information on the basis of said image, said substrate-position information indicating the position at which said circuit substrate is held by said substrate holding device; and a working device operable to perform the predetermined working operation on said circuit substrate, on the basis of said substrate-position information, and wherein said imaging control device includes a substrate-identification control portion operable to control said imaging device to take an image of a substrate ID mark provided on said surface of the circuit substrate as held by said substrate holding device, said substrate-identification control portion obtaining substrate identifying information identifying said circuit substrate, on the basis of said image of said substrate ID mark.
