ABSTRACT:
An improved cutting apparatus and method used in a wire scribing device, said cutting apparatus having a cutter blade attached to a wiring head, and having a z-axis actuator for precisely controlling the movement of the cutter blade in the z-direction. A gauge height finder, attached to the wiring head determines a distance between the wiring head and the substrate, wherein the determined distance is used to control the z-axis actuator for lowering the cutter blade so as to precisely cut the conductor on the surface of the substrate. Furthermore, the cutting apparatus may include a cutter bracket attached to the wiring head, having a preloaded spring fixed thereto. Wherein this spring is preloaded to a preset force and wherein the spring is positioned above the cutter blade so that an upward force on the cutter blade is transmitted to the spring.
