ABSTRACT:
Centering elements for effectively reducing the clearance between a shaft and a rotatable element, such as a blade-fixing flange of a dicing saw for semiconductor substrates or carrier substrates, installable thereon are disclosed. In addition, the centering elements may be used to substantially align a center of mass of a rotatable element installed onto the shaft with the axis of rotation of the shaft. The centering element may position the center of mass of a rotatable element at a position that is in substantial alignment with the axis of rotation. Methods for assembling rotatable elements onto shafts and methods for balancing such rotatable elements are also disclosed. Multiple fixtures as well as multiple centering elements may be employed. In addition, one centering element may position more than one fixture.
