Conventional chip-handling techniques employ vibratory bowl feeders or other chip-orienting devices which take unmounted chips in random orientations and preferentially orient them in a desired orientation and then advance the chips along a track where they can be picked up by a vacuum pencil. Some problems which arise due to this conventional chip-handling technique include excessive damage to the chips due to the vertical pickup operations and the vibratory bowl orientation operations. These problems are solved by the device transfer block assembly invention which is disclosed as follows. The device transfer block assembly finds specific application in the test system disclosed in [1,2]. The device transfer block assembly is shown in Figs. 1 and 2, and handles chips as opposed to integrated circuit modules. Fig.
