# Rambus handler

## 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.
