  • Capacitive clamping process for cleaving work pieces using crack propagation
    Patent number: 9718215
    Abstract: Controllable cleavage of a work piece is achieved through the use of capacitive clamps and application of a large tensile force. Capacitive clamps are used to secure the ends of a work piece with strong electrostatic forces. The capacitive clamps secure the ends of the work piece by creating electrostatic forces like those experienced by the plates in a parallel plate capacitor. After introduction of a crack along a side surface of the work piece, the application of a tensile force along the central axis of the work piece causes the crack to rapidly propagate and cleave the work piece into two or more pieces.
