ABSTRACT:
A vacuum collet for handling semiconductor piece parts is formed to include a plurality of separate vacuum ports, disposed in proximity to one another. By selectively turning the vacuum ports "on" and "off", with only one vacuum port turned "on" at a time, a semiconductor chip may be articulated through various 90.degree. rotations to provide the orientation required for placement of the semiconductor chip on a final assembly.
