Abstract
A novel ultrasonic transducer comprises a machined solid metal unibody having a rectangular aperture in the center between a tool mounting end and a balanced end. The end portions are connected by two axial side members which connect to two transverse sides of the rectangular aperture. A stack of piezo electric crystals are mounted in said rectangular aperture between the transverse sides and spaced apart from the axial sides of the aperture. A bonding tool is mounted in a cylindrical aperture in the mounting end of the transducer and tightly mechanically coupled to the mounting end so that the stack of piezo electric crystals are acoustically coupled through the unibody to the bonding tool in a cylindrical aperture by a tightly coupled mounting surfaces.
