Abstract: <P>PROBLEM TO BE SOLVED: To provide a method of producing CAM data for an electronic circuit board by which the CAD data of line conductors or surface conductors can be properly and efficiently converted into CAM data composed of plating windows of the exposure mask for pattern plating.  <P>SOLUTION: The extension ratio ηof the line width for CAD/CAM conversion of the figure data of line conductors into the figure data of plating windows is controlled to be larger in a line conductor having small line width than in a line conductor having large line width.
