After Peeling Inspection


FPI disc MP is a special version of FPI disc MA and is used for an additional optical disc camera inspection (beside final inspection by IQPC inline scanner) at an intermediate process stage. E.g. production of BD-R-DL applies the 2P process, using a stamper disc which is separated after bonding. This 'peeling process' is very sensitive and may cause many defects. It would be waste of money, to complete such defective discs and sort them out by final scanner at the end of the process.

dr. schwab offers a solution based on 4 megapixel matrix camera, inspecting the disc's surface within 100 ms. This allows to inspect the disc during an ordinary stop of the turntable transporting the discs to the next station.
