  • Publication number: 20180188318
    Abstract: A test handler for testing electronic components comprises a rotary turret for conveying electronic components, a first input station and a second input station, the first and second input stations each being operative to separately feed electronic components to the rotary turret for conveying the electronic components. The electronic components fed only from the first input station are tested at a first set of test stations comprising a plurality of first test platforms, and the electronic components fed only from the second input station are tested at a second set of second test stations comprising a plurality of second test platforms. For removing the electronic components from the rotary turret, a first off-loading station receives electronic components fed only from the first input station and a second off-loading station receives electronic components fed only from the second input station.

  • Patent number: 9519007
    Abstract: A handling system for testing electronic components comprises a rotary turret and pick heads mounted on the rotary turret, each pick head being configured to hold a respective electronic component provided by a supply source. A carrier system which is positionable adjacent to the rotary turret is configured to carry a plurality of electronic components. The carrier system is receivable by a testing station that is operative to simultaneously test a plurality of the electronic components which have been arranged on the carrier system. The pick heads or other transfer mechanism may transfer the electronic components onto the carrier system prior to testing the same at the testing station and remove electronic components from the carrier system after testing the same at the testing station.
