A gripper has been developed for picking and placing semiconductor modules during manufacturing operations. The device makes it possible to pick or place three modules at a linearly oriented hopper track station, change their relative orientation, and then place or pick them at a turntable station. In the manufacturing process three linearly arranged hopper tracks at the linear station (Fig. 1) have modules placed in either the pass 1 or fail 2 locations or picked from the untested 3 location. At the circular station, modules 4 are tested in the test socket 5 as the turntable 6 rotates (7). The task of the gripper is to place and pick the modules, as required, for testing and removal.
