Patent ID: 8653843

Claim:
An electronic device testing apparatus for conducting a test on an electronic device by transmitting a test pattern to said electronic device to be tested and detecting a response pattern thereto, comprising: a temperature control device, comprising: a heater for dynamically heating said electronic device to be tested; a cooler comprising a peltier element for cooling or heating said electronic device to be tested; a heat sink connected thermally to said cooler, for cooling or heating a heat release surface of said cooler; and a controller for generating a power consumption canceling pattern based on a power consumption of an electronic device to be tested by said test pattern and dynamically controlling heating power of said heater; and a pusher for pressing an electronic device to be tested against a contact terminal, to which a test pattern is input, wherein the cooler is provided to said pusher so as to dynamically contact with said electronic device to be tested, for cooling or heating said electronic device to be tested.
