PURPOSE:To produce and check a film for production of a printed circuit board quickly and easily by superposing a film, which is generated with a punching machine through an NC tape for production of the printed circuit board, a punching machine and an art work film. CONSTITUTION:NC tape information for punching is stored as data in a microcomputer, and data for actual punching is generated in the microcomputer, and dots, for example, black round dots (black circles) are plotted on a transmissive film on a basis of this data. The film produced in this manner and the art work film are superposed after alignment to produce a film for the printed circuit board and check the NC tape for production of the printed circuit board. |
