Abstract:
1. A test handler, comprising: a loading unit for loading semiconductor devices of user trays onto a test tray; a test chamber in which a tester tests the semiconductor devices loaded on the test tray by the loading unit; and an unloading unit for unloading the semiconductor devices tested in the test chamber from the test tray onto user trays, wherein the loading unit includes: at least one moving type loading table, movable between a first region and a second region, having device-settling cells arranged to have a pitch wider in a first direction than a pitch in the first direction between the semiconductor devices loaded on the user trays, the pitch of the device settling cells in the first direction being substantially the same as a pitch in the first direction on the test tray, and a pitch of the device settling cells in a second direction, which is substantially orthogonal to the first direction, being substantially the same as a pitch between the semiconductor devices loaded on the user trays in the second direction; a first picking apparatus movable in the first region to transfer and load the semiconductor devices from the user trays to the device-settling cells of the moving type loading table positioned in the first region, wherein a pitch of the first picking apparatus in the first direction is adjustable and a pitch of the first picking apparatus in the second direction is fixed; and a second picking apparatus movable in the second region to transfer and load the semiconductor devices from the device-settling cells of the moving type loading table positioned in the second region to the test tray, wherein a pitch of the second picking apparatus in the second direction is adjustable and a pitch of the second picking apparatus in the first direction is fixed and further wherein a pitch of the tray is wider in the second direction than the pitch of the device-settling cells in the second direction.
