<p>A bond head (10) is provided for a wire bonding machine having a linear axis frame (14), a rotary axis frame (16), a bond tool (11) and a wire clamp (52). The linear axis frame (14) is vertically linearly displaceable along a linear axis, while the rotary axis frame (16) is rotationally displaceable along a rotary axis. A pivotal connector (26) is provided which pivotally connects the rotary axis frame (16) to the linear axis frame (14), enabling the rotary axis frame (16) to rotate independent of linear displacement of the linear axis frame (14). The bond tool (11) is connected to the rotary axis frame (16) and is vertically linearly displaceable in response to vertical linear displacement of the linear axis frame (14) and rotationally displaceable in response to rotational displacement of the rotary axis frame (16). The wire clamp (52) is connected to the linear axis frame (14) and is vertically linearly displaceable in response to vertical linear displacement of the linear axis frame (14), while the wire clamp (52) is maintained rotationally stationary during rotational displacement of the rotary axis frame (16). The bond head (10) also includes a linear motion assembly and a rotary motion assembly. The linear motion assembly has a linear driver (70), a linear position detector (72) and a linear driver controlled (74). The rotary motion assembly correspondingly has a rotary driver (88), a rotary position detector (90) and a rotary driver controller (92).</p> |
