ABSTRACT:
A wire bonding apparatus10including an X table18guided to move in the X direction on an XY table base14and a driving motor20mounted on a motor base16with the movable element22of the driving motor20connected to the X table18. The motor main body24is guided by a pair of motor guides26so as to be movable in the X direction via the laminated bodies40. In each laminated body40, viscoelastic flat rubber plates that have a spring element and a damping element, and flat rigid plates, are alternately disposed and laminated, so that the rigidity is large in the direction perpendicular to the laminated surfaces, and the rigidity is small in the direction parallel to the laminated surfaces, and the laminated bodies have a recovery force and a damping force due to the viscoelasticity.
