Abstract
A method of operating a wire bonding machine is provided. The method includes the steps of: (a) supporting a substrate on a material handling system of the wire bonding machine; (b) changing a bend profile of the substrate; and (c) securing, after step (b), the substrate against a support structure of the wire bonding machine using a clamping element of the wire bonding machine, the support structure for supporting the substrate during a wire bonding operation, and the clamping element for securing the substrate to the support structure during the wire bonding operation.
