Abstract:
A bonding system for bonding wires between a first electrical contact surface on a semiconductor chip and a second electrical contact surface on a substrate, the bonding system comprising:a data processing device; a user-operable input device coupled to the data processing defice that generates operating commands for the system; an output display device coupled to the data processing device; first and second memory devices coupled to the data processing device; the first memory device having a master bond program stored theron that defines parameter values for a series of bonding steps involving a semiconductor slip and the substrate; the data processing device being responsive to an operating command to generate and operating bond program by transferring a copy of the master bond program from the first memory device to the second memory device; the data processing device being responsive to a further operating command to: generate an modified value of a selected parameter of the operating bond program; compare the modified value with the original value of the selected parameter in the master bond program; and replace the original value of the selected parameter with the modified value in the operating bond program but not in the master bond program if the modified value is within a predetermined tolerance of variation for the selected parameter.
