MT 9510

Test handlers are automated backend machines that present packaged semiconductor devices to an electrical tester. Test handlers of this class are used after assembly, when singulated packaged parts must be temperature conditioned, contacted, tested, and sorted.

Pick-and-place test handlers move packaged devices from input media to a test position, hold the device in a socket or contactor during electrical test, and then route the device to an output location based on the result. Tri-temperature handlers of this class combine device transport with thermal conditioning so the tester can execute programs at cold, ambient, or hot conditions.

Test handlers fit in the semiconductor backend flow after package assembly and before final packing. A machine in this class operates alongside automated test equipment, with the handler managing device presentation and temperature while the tester provides electrical stimulus and measurement.

Handlers in this class are used for final test of packaged semiconductor devices that need controlled temperature and repeatable socketing. Typical uses include logic, analog, mixed-signal, sensor, and power-related packaged parts, especially where thermal screening or multisite production test is required.
