Abstract:
A combined system for automatically bonding and testing wire connections attached to an integrated circuit chip having at least one bonding pad and to a substrate having at least one contact pad remote from said bonding pad, comprising:a computer to control said bonding and testing; a wire bonder operable to extend a wire span from said bonding pad to said contact pad, and to create wire attachments onto both said pads, said bonder following instructions from said computer; an X-Y table, in combination with said bonder, suitable to position said chip mounted onto said substrate; means controlled by said computer for adjusting the relative positions of said bonder and said table, one to the other; a testing apparatus in combination with said bonder, operable to exert forces controlled by said computer for testing the bonding quality, and to store the data of said testing in test files; and a data converter, coupled to receive said test data, operable to convert said data into instructions for adjusting the computer control of the bonding parameters for subsequent wire bond spans and attachments to be created by said bonder, whereby the number of faulty bonds is reduced to near zero and bonding production downtime is substantially eliminated.
