Abstract:
A machine for making ultrasonic wire bonds comprising;a. positioning means for translating an ultrasonic bonding tool to thereby position the tip of said tool to precisely pre-determinable positions within a coordinate space, said positioning means including: I. a support plate, a first Y-axis tool support platform, means for translatably supporting said first platform by said support plate and first drive motor means for translating said first platform with respect to said support plate, and II. a second, X-axis tool support platform, means for translatably supporting said second platform by said first, Y-axis tool support platform, and second drive motor means for translating said second platform with respect to said first, Y-axis tool support platform, b. transducer support means for supporting an ultrasonic transducer, c. an ultrasonic transducer, d. an ultrasonic bonding tool mechanically coupled to said ultrasonic transducer, said bonding tool having a bore therethrough for receiving a bonding wire, e. coupling means for coupling said transducer support means to said positioning means, and f. actuating means for manipulating bonding wire threaded through a bore provided through said bonding tool.
