Patent ID: 8026735

Claim:
A test handler comprising: a first loading member on which a plurality of semiconductor devices are loaded; a second loading member for loading the plurality of semiconductor devices; a pick and place apparatus for transferring and supplying the semiconductor devices of the first loading member to the second loading member; a transferring apparatus for transferring and stopping the second loading member based on an inputted transfer value, wherein the transfer value corresponds to at least two columns of inserts in a lengthwise direction; and an insert-opening apparatus for assisting the pick and place apparatus to load the semiconductor devices to the second loading member, wherein the insert-opening apparatus is composed of at least two opening units that correspond to one part of the second loading member and at least two opening units that simultaneously open the corresponding inserts, wherein the second loading member repeatedly performs being transferred and stopped in response to the semiconductor devices supplying operation of the pick and place apparatus such that the supplying position of the pick and place apparatus to the second loading member is substantially invariant.
