Abstract
A handling system for devices under test (DUTs), i.e. semiconductor chips. A rotatable platform is provided which platform has a plurality of boats or nests. The DUTs are inserted in the boats. The platform carrying the DUTs is indexed through a plurality of treatment stations to precondition the chips specifically to bring the chip to a test temperature. At a test station, the chip is removed from the boat and inserted into a manufacturer's test head. The chip is tested, returned to the boat and indexed to a treatment station(s) downstream of the test head where is ultimately removed for further processing.
