TRACEABILITY SYSTEM OF SHEET-LIKE PHOTOSENSITIVE MATERIAL

摘要

PROBLEM TO BE SOLVED: To provide a traceability system by which a necessary sheet-like photosensitive material is found out easily. SOLUTION: A manufacturing line for the sheet-like photosensitive material comprises: two or more processes S1 to S6; and a manufacturing information management computer 50 for managing these processes wholly. The manufacturing information management computer 50 provided with a database 54 stores indication information to be sent to each process and actual results produced at each process to control them unitarily. A process history and a current position of the sheet-like photosensitive material is known by searching information in the database 54. COPYRIGHT: (C)2007,JPO&INPIT
