ABSTRACT

A test handler for automatically testing rambus type semiconductor devices.
The rambus type test handler includes a user tray stacker for stacking a
plurality of user trays which are loaded with semiconductor device that have
been, or will be tested; a device loading portion for picking up the
semiconductor devices from the user trays at a supplying position and loading
the semiconductor devices onto boats at a loading position; a heating/cooling
chamber for heating or cooling the boats according to test requirements by
order of boat receipt from device loading portion; a test chamber for
connecting the heated or cooled semiconductor devices to test sockets for
testing; a recovering chamber for recovering the temperature of the
semiconductor devices to a normal degree, while elevating the boats and
discharging the boats through an upper end, sequentially, by order of boat
receipt from a lower end of the test chamber; a device sorting portion for
picking up test-completed semiconductor devices from the boats discharged from
the recovering chamber and stacking respective grades of semiconductor devices
to correspondingly predetermined areas of a plurality of conveying buffers;
and a device unloading portion for stacking the semiconductor devices from the
conveying buffers to the user trays corresponding to the respective grades of
the semiconductor devices. Further, there are provided a device loading
portion, displaceable hand for sorting the semiconductor devices, contact
picker assembly of the test chamber, and position guiding portion.
