<p>A flexural pivot structure useful in a wire bonding machine bonding head (10) is disclosed and includes first and second leaf spring assemblies (39, 41) which provide a pivot axis (PA) displaced from the pivoting structure. Each leaf spring assembly includes leaf spring arm (39a, 39b, 41a, 41b) extending outwardly from a central mounting position (39c, 41c) so that each assembly forms a truncated vee. The center portions of the leaf springs are secured to a transducer bridge (25) in which transducer (59) is mounted. The ends of the leaf springs are secured in a bracket (11) with respect to which the transducer (59) pivots about an axis located at the intersection of converging lines along the leaf springs (39a, 39b, 41a, 41b) of each leaf spring assembly (39, 41).</p> |
