Abstract
An electric device testing apparatus comprises a connection terminal to which an IC chip to be tested is removably connected, a pusher for pushing the IC chip in the direction of the connection terminal in order to connect the IC chip to the connection terminal, and temperature adjusted air supply for blowing a temperature adjusted air to around the IC chip during a test on the IC chip via a through hole formed on the pushed.
Claims22
An electric device testing apparatus comprising:
- a test tray on which electric devices to be tested are held and which is carried in the electric device testing apparatus;
- a connection terminal to which the electric device to be tested is removably connected in a state of being held on said test tray;
- a pusher for pushing the electric device in the state of being held on the test tray against said connection terminal in order to connect the electric device to said connection terminal, the pusher having a ventilation hole;
- and
- means for adjusting a temperature of the electric device which generates heat by itself during a test on the electric device via the hole formed on said pusher, the temperature adjusting means includes temperature adjusted gas supply means for blowing a temperature adjusted gas directly to the electric device under test in the state of being held on the test tray via the ventilation hole.
An electric device testing apparatus comprising:
- a test tray on which electric devices to be tested are held and which is carried in the electric device testing apparatus;
- a connection terminal to which the electric device to be tested is removably connected in a state of being held on said test tray;
- a pusher for pushing the electric device in the state of being held on the test tray against said connection terminal in order to connect the electric device to said connection terminal, the pusher having a drawing hole;
- and
- means for adjusting a temperature of the electric device which generates heat by itself during a test on the electric device via the hold formed on said pusher, and said temperature adjusting means includes air drawing means for drawing an air around the electric device during the test on the electric device which is held on the test tray via the drawing hole.
An electric device testing apparatus for performing a test by pushing a terminal of an electric device to be tested against a connection terminal of a heat head, comprising:
- a test tray on which the electric devices to be tested are held and which is carried in the electric device testing apparatus;
- a suction head for picking up the electric device being held on the test tray by sucking the electric device and pushing the terminal of the electric device to be tested against the connection terminal of a test head in the state of sucking the electric device;
- suction force giving means for giving a suction force to said suction head;
- and
- suction force crushing means for releasing:the suction force of said suction head, the suction force crushing means blows fluid for releasing the suction force of said suction head directly to the electric device pushed against said suction head for any period of time during the test on the electric device in order to adjust a temperature of the electric device which generates heat by itself during a test.
An electric device sucking apparatus for sucking and releasing an electric device, comprising:
- a suction head for sucking up and releasing the electric device;
- suction force giving means for giving a suction force to said suction head;
- and
- suction force crush means for releasing the suction force of said suction head, the suction force crush means blows fluid on directly on the electric device for releasing the suction force of said suction head in order to adjust a temperature of the electric device which generates heat by itself when the electric device is held at a fixed position.
