Abstract:
1. An apparatus for manufacturing an electronic circuit board on which are provided a plurality of first wirings placed side by side, a plurality of second wirings placed in a direction across from the plurality of the first wirings, and electric circuit patterns formed as a combination of the plurality of the first wirings and the plurality of the second wirings, comprising: a defect detecting part detects a defect by electrically inspecting each of the plurality of the first wirings and the plurality of the second wirings and specifies an electric circuit pattern which has the defect; a defect-type specifying part specifies a type of the defect in the electric circuit pattern which has been detected through the electric inspection; a defect position specifying part acquires an image of the specifying electric circuit pattern that contains the defect and detects a position of the defect in the acquired image; a modification specifying part selects a defect existing region information stored in a storage device according to the type of the defect and determines a method of correcting the defect by comparing the position of the defect to the defect existing region information; and a defect correcting part corrects a defect existing area, wherein each of the plurality of the first wirings and each of the plurality of the second wirings forms data wirings and gate wirings; wherein specific position numbers of the gate wirings and the data wirings determines a location of a short-circuit; and wherein the defect type is specified according to which data wirings and gate wirings causes the short circuit.
