Patent ID: 7508191

Claim:
A system for testing a plurality of devices-under-test, the system including a tester having a test resource for performing a distinct test and a pin electronics card, comprising: a first pin of the pin electronics card; a second pin of the pin electronics card; a muxing relay of the pin electronics card, connected to the tester resource and to the first pin and the second pin in parallel for operative switching of the tester resource between application to either of the first pin and the second pin; a handler connected to the tester, having a first manipulator and a second manipulator, the handler controls the mux relay to operatively switch testing by the tester resource to either of the first pin and the second pin, according to the handler's detection of a device-under-test positioned for testing in either of the first pin and the second pin, respectively; wherein, during testing at the first pin, the first manipulator maintains a device-under-test in connection to the first pin for testing, and the second manipulator, during testing at the first pin, disconnects from the second pin any device-under-test then having just been tested at the second pin; and, during testing at the second pin, the second manipulator maintains a next device-under test in connection to the second pin for testing, and the first manipulator, during testing at the second pin, disconnects from the first pin any device-under-test then having just been tested at the first pin; a test initiator generated by the handler upon the handler's detection that a device-under-test is then positioned for testing in connection to either of the first pin and the second pin, wherein the tester commences testing via the test resource in response to the test initiator of the handler; wherein, at each instant during testing operations by the tester for the plurality of devices-under-test, the test resource, via the operative switching of the muxing relay by the handler according to the handler's detection that the handler then maintains one of the plurality of the devices-under-test in position for next testing at either the first pin and the second pin, respectively, tests at either of the first pin and the second pin, in substantially immediate index-less succession at each instant, for all of the plurality of devices-under-test, unless and until the testing is interrupted.
