1.1 These test methods cover tests to determine the shear strength of a series of ball bonds made by either thermosonic or thermal compression techniques using either gold or copper wires.
Note 1: Common usage at the present time considers the term “ball bond” to include the enlarged spheriodal or nailhead portion of the wire, (produced by the flameoff/spark [EFO] and first bonding operation in the thermosonic [or thermal compression] process), and the ball bond-bonding pad interfacial-attachment area or weld interface.
