METHOD FOR REVISING TWO-TERMINAL COMPONENT MOUNT DIAGRAM

PURPOSE:To provide a method for revising a 2-terminal component mount diagram with very less increase in trouble with respect to the method for revising a 2-terminal component mount diagram in which a net number of a net connecting pins of 2-terminal components are replaced in the CAD system. CONSTITUTION:A printed circuit board component mount diagram having a 2-terminal component mount diagram including the 2-terminal component mount direction and number of a net connecting two pins of each 2-terminal component is read in the step S1, a revision diagram in which the net number of the net connecting two pins of each 2-terminal component is replaced is read in the step S2, the 2-terminal component mount diagram of the printed circuit board mount diagram and the revised diagram are compared in the step S3 to detect the net number of the net connecting pints of each 2-terminal component to be revised, the mount direction of the 2-terminal components in the 2-terminal component mount diagram of the printed circuit board component mount diagram is inverted in the step S4 and the net number of the net connecting pints of the 2-terminal components is replaced.
