Patent ID: 7619432

Claim:
A system for testing a first device under test (DUT) and a second DUT, the system including a tester, the tester providing a tester resource for a distinct test, the tester resource segregatedly connectable to the first DUT and the second DUT, respectively, comprising: a handler, including a first positioner and a first unit and a second positioner and a second unit, the handler manipulates the first DUT to the first unit and the handler manipulates the second DUT to the second unit; a relay connected to the handler and the tester; a first socket connectable by the relay to the tester resource for the distinct test by the relay, the first positioner of the handler manipulates the first DUT from the first unit to the first socket for the distinct test; a second socket connectable by the relay to the tester resource for the distinct test, the second positioner of the handler manipulates the second DUT from the second unit to the second socket for the distinct test; wherein the distinct test is performed on the first DUT in the first socket, as the second DUT is removed from the second unit and posited in the first socket by the handler; wherein the distinct test is performed on the second DUT in the second socket, as the first DUT is removed from the first unit and posited in the second socket by the handler; wherein the handler, as master, (i) switches the relay, as slave, to respectively connect to the first socket after the distinct test is performed on the second DUT in the second socket and to the second socket after the distinct test is performed on the first DUT in the first socket and (ii) activates the tester, as slave, to commence testing by the tester via the distinct test.
