Abstract
A device testing apparatus including a connection terminal to which an electronic device under test is detachably attached, a pusher for pushing the electronic device in the direction of the connection terminal so as to connect the electronic device to the connection terminal, and a cooling unit for cooling the electronic device. As the cooling unit, an element cooling the device using electricity is for example used. The cooling unit includes a cooling medium blower for blowing a cooling medium around the electronic device and heat exchange projections or depressions for raising the cooling efficiency by blowing a cooling medium. In the device testing apparatus, even if the electronic device generates heat on its own during testing, the electronic device is cooled through the pusher, connection terminals, or socket, so the effect of the heat generated by the electronic device is canceled out and the electronic device can be tested at the predetermined temperature as prescribed in the specification.
