摘要:
In a handler comprising a movable head (suction pads) capable of holding and conveying a plurality of pre-test IC devices at a time: when conveying a plurality of pre-test IC devices from a supply customer tray KST to a test tray TST, a first step of leaving on the customer tray KST pre-test IC devices loaded on positions corresponding to turned-off sockets, holding by the suction pads only pre-test IC devices on the customer tray KST loaded on positions corresponding to other sockets than the turned-off ones and conveying them from the customer tray KST to the test tray TST without changing the arrangement; and a second step of conveying pre-test IC devices left on the customer tray KST for the reason of being at positions corresponding to the turned-off sockets from the customer tray KST to positions on the test tray TST corresponding to other sockets than the turned-off sockets are performed.
摘要:
An electronic device test apparatus used for bringing the ICs into electrical contact with contact parts of the test head in the state where the ICs are held on a test tray and running tests on the electrical characteristics of ICs, the electronic device test apparatus including an inversion system for rotating the test tray which holds a plurality of ICs in a direction dropping ICs which are insufficiently held at least once before testing.
