ABSTRACT:
A system for positioning an electronic test head of a test system with respect to an electronic device handler. A positioner assembly moves vertically and provides substantial movement in the horizontal plane with six degrees of freedom. The positioner assembly includes a section for attaching the test head. A counterbalancing assembly is coupled to the positioner assembly to provide a substantially weightless condition to the positioner assembly with the test head attached.
