Cooling fin connected to a cooling unit and a pusher of the testing apparatus
View Patent ↗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.
1. A device testing apparatus comprising:
a tray for testing while pushing terminals of a plurality of electronic devices carried on the tray against contact portions of a test head;
a pusher for pushing each of the plurality of electronic devices held on the tray in the direction of the contact portions; and a heat absorbing and radiating member provided at the pusher,
wherein the pusher comprises: a pusher base provided to be able to approach and move away from a contact portion and a pusher block provided integrally or separately from the pusher base and contacting an electronic device from the surface opposite to the contact portion to push the same, and
wherein the pusher block is configured separate from the pusher base and further comprises an elastic member imparting elasticity in the pushing direction of the electronic device to the pusher block.
2. The device testing apparatus as set forth in claim 1 , wherein the heat absorbing and radiating member is provided between elastic members.
3. The device testing apparatus as set forth in claim 1 , wherein heat absorbing and radiating members are provided at the two sides of an elastic member.
4. A device testing apparatus comprising:
a tray for testing while pushing terminals of a plurality of electronic devices carried on the tray against contact portions of a test head;
a pusher for pushing each of the plurality of electronic devices held on the tray in the direction of the contact portions; and a heat absorbing and radiating member provided at the pusher,
wherein the pusher is formed with a nozzle for guiding temperature control gas, separate from the gas flow in the chamber for maintaining the electronic device at a predetermined temperature, in the direction of the heat absorbing and radiating member.
5. The device testing apparatus as set forth in claim 1 , wherein the heat sink is formed integrally with at least part of the pusher.
6. The device testing apparatus as set forth in claim 4 , wherein the heat sink is formed integrally with at least part of the pusher.
