  • Arrangement for subjecting a bonding wire to a mechanical load
    Patent number: 6668667
    Abstract: An arrangement in which a first contact surface (2) for bonding one end (51) of the bonding wire (5) and a piezoelectric actuator (3) are fixed on a support body (1) and a second contact surface (4) for bonding another end (52) of the bonding wire (5) is fixed to the actuator by an unsupported support body (34). The second contact surface moves back and forth in relation to the support body by means of an actuator, at a frequency of between 0.1 Hz and a few KHz and in one or more directions (31, 31′, 31″). The arrangement is suitable for use in testing the endurance of bonding wire connections.
