ABSTRACT:
A wire clamper for wire bonding apparatuses including a pair of clamping arms provided with clamping elements at the terminal ends of the clamping arms that are opened and closed by the electrostrictive strain effect or magnetstrictive strain effect of a piezoelectric element, and a temperature compensation component is connected to the piezoelectric element so as to correct the fluctuation in the clamping load in the clamping elements that are caused by temperature changes in the clamper.
