1. A bonding apparatus comprising:
an oscillation amplification device having a longitudinal axis;
a mounting barrel coupled to the oscillation amplification device;
an ultrasonic driver coupled to the oscillation amplification device at a first position along the longitudinal axis; and
a bonding tool mounted to the oscillation amplification device at a second position along the longitudinal axis spaced from the first position;
wherein the oscillation amplification device has a substantially triangular cross-sectional area on a plane that is orthogonal to the longitudinal axis,
the bonding apparatus further comprising a clamp that is configured to clamp the mounting barrel at clamping positions located away from the vertices of the triangular cross-sectional area such that each clamping position is generally aligned with a side of the triangle.
