Abstract:
A temperature-controlled testing system comprising:a conveyor mechanism configured to carry a device to be tested;a first temperature control zone adapted to receive the device on the conveyor mechanism, and configured to bring the device to a first temperature;a second temperature control zone adjacent to the first temperature control zone and adapted to receive the device on the conveyor mechanism, the second temperature control zone including at least one heat transfer element as a heat exchanger to bring the device to a second temperature; anda test zone adjacent to the second temperature control zone, the test zone including a test head arrangement configured to receive the device to be tested and to hold the device to be tested in a known fixed position relative to the test head arrangement, wherein the test head arrangement includes contact means configured to make electrical contact to a plurality of leads of the device to be tested, the test zone further including heat transfer elements attached to the test head arrangement which bring the temperature of the contact means to substantially the second temperature.
