ABSTRACT:
A transducer for a wire bonding apparatus is formed of two separate parts sandwiching therebetween a plurality of piezoelectric elements. One of the two parts is the amplifying horn, and by selecting appropriate sizes and shapes for the two parts, vibrational energy can be concentrated at the distal end of the amplifying horn where the bonding tool is located.
