摘要:
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.

A semiconductor device testing apparatus having a reduced transverse width and compact in size is provided. Adjacent to a constant temperature chamber containing therein a vertical transport means is located a test chamber which is in turn adjoined by a temperature-stress removing chamber likewise containing therein a vertical transport means, so that the constant temperature chamber and the test chamber are arranged transversely in a line, while the temperature-stress removing chamber is located in front of the test chamber when viewed in front view of the apparatus. Further, a loader section is located in front of the constant temperature chamber, and an unloader section is located above the temperature-stress removing chamber. With this arrangement, the transverse width of the testing apparatus may be reduced to about two test tray lengths.

An ink composition for ink jet recording is described comprising a pigment, a resin dispersant, a thermoplastic resin emulsion and water, wherein the weight ratio of the pigment to the resin dispersant is from 20:1 to 5:2. The foregoing ink composition is little susceptible to irregular bleeding on a recording medium, undergoes no change in physical properties and jettability and no precipitation of solid matter and exhibits an excellent redispersibility.

An IC device transfer method for IC handler accommodates both a tray and a rod-shaped magazine. The tray installs a plurality of IC devices which transport in horizontal directions in the IC handler. The rod-shaped magazine installs a plurality of IC devices which transport in vertical directions in the IC handler. A device reinspection method in the IC test handler reinspects the IC devices stored in the tray or magazine without human intervention, sorts in accordance with the test results, and stores in either the rod-shaped magazine or the tray. For this purpose, a tray supply section transfers a user tray to a test tray, whereas a magazine supply section and a pick carrier section transfer a rod-shaped magazine to the test tray. An inspection setting sets the number of reinspection, the classification of inspection results, and the storage tray/magazine. The IC devices are loaded from the magazine and the user tray to the test tray and are tested. When a reinspection mode is effective, the IC devices to be reinspected are stored in the unloader section and transferred to the loader section by the tray transfer system to test the IC devices again. When the reinspection mode is completed, the IC device are sorted by categories and stored in the tray/magazine.
