Abstract: A kinematic coupling for a test system with a test head which must be docked with a handling device. The coupling is implemented with a plurality of modules attached to the test head. Each module has one kinematic surface and is designed to mate with another kinematic surface on the handling device. Each module includes a motor which can extend or retract the kinematic surface. These modules allow docking of the test head to the handling device with a final motion perpendicular to the handler. They also allow the tilt angle between the test head and the handler to be adjusted to achieve planarization.
