What it is
How it works
General reference — not yet source-verifiedTest head manipulators provide a movable platform that carries the test head and allows it to be adjusted in X, Y, Z, and tilt axes. The manipulator typically uses a combination of mechanical linkages, slides, and counterbalance springs or air cylinders to enable smooth and safe movement. Once the test head is positioned over the prober or handler chuck, a docking mechanism locks it into place to maintain alignment during testing.
Where it fits in the process flow
General reference — not yet source-verifiedTest head manipulators are used in the semiconductor test floor, bridging the automatic test equipment (ATE) and the prober or handler. In wafer sort, the manipulator docks the test head to a prober that contacts individual die on the wafer. In final test, it docks the test head to a handler that presents packaged devices. The manipulator enables rapid changeover between different test setups and device types.
