Operation
The wafer attached to Flat Ring is placed onto the table of the breaker from the cassette automatically. In the image system, the laser cutting line level is adjusted automatically, and the laser cutting traverse level is adjusted automatically. After the locations of Y-axis and cutter-axis are searched on the edge of the wafer, breaking (in X and Y directions) is performed according to the recipe of the work piece types. After breaking is complete, the operator unloads the work piece.
