Patent ID: 7919974

Claim:
A method of configuring an electronic device handling apparatus for bringing DUTs into electrical contact with contacts of a test head, the method comprising: modularizing a handling unit and a test unit forming the apparatus so as to enable exchange, add or reconfigure of the handling unit and the test unit; and selecting the handling unit having a corresponding throughput from among a plurality of handling units and the test unit having the corresponding number of simultaneous measurements from among a plurality of test units, on the basis of a maximum number of measurable pins of a tester, a number of terminals of the DUTs, and a test time of the DUTs, wherein the handling unit comprises a stocker unit, a loader unit and an unloader unit, and wherein the stocker unit comprises: a first stocker configured to store customer trays on which a plurality of pre-test DUTs are held; a second stocker configured to store customer trays on which a plurality of tested DUTs are held; and a tray conveyor configured to move a customer tray to the loader unit or the unloader unit, the loader unit has a first transfer device configured to transfer the pre-test DUTs from the customer tray to a test tray and move the test tray to the test unit, the unloader unit receives the test tray from the test unit and has a second transfer device configured to transfer the tested DUTs from the test tray to the customer tray, and the test unit receives the test tray from the handling unit and brings the DUTs into electrical contact with the contacts while the DUTs are held on the test tray, wherein the plurality of handling units differing in operating speed of the first transfer device and/or the number of the DUTs which are simultaneously held by the first transfer device.
