Abstract:
An apparatus for moving a bonding head of a wire bonder in X, Y and Z axial directions, comprising:a linear guide member for guiding said bonding head in the X and Y axial directions;a XY moving means for providing a moving force in the horizontal (X and Y axial) directions to said linear guide member by causing an induced electromotive force;a Z moving means for providing a moving force in the vertical (Z axial) direction to a block of said bonding head by causing an induced electromotive force, said Z moving means including a main body having an upper plate, a lower plate, and two side plates spaced from each other, first and second pluralities of magnets disposed on an inner surface of each of said two side plates, respectively, to create an attraction inside said main body, a coil moved in the Z axial direction by said induced electromotive force created by said Z moving means, and means for connecting said block to said coil; anda hinge means for converting said moving force of said Z moving means into a rotating force, and functioning as a rotation center so that said block is rotated in an opposite direction to a wire clamp motion.
