  • Monitoring system for dicing saws
    Patent number: 6165051
    Abstract: A method and apparatus for accumulating dicing data for process analysis, monitoring process stability and cut quality in a substrate. The apparatus has a sensor for determining a speed of a blade of the dicing saw. A monitor determines a load placed on the blade by the substrate, where the monitor measures at least one of a feedback control current and a feedback control voltage output from the dicing saw. A controller is coupled to the monitor in order to control the spindle driver responsive to the load induced on the blade by the substrate.
