| abstract | PURPOSE: To improve the quality guarantee by inserting a Peltier element between a chip sucking mechanism and a water cooling plate. n CONSTITUTION: The Peltier element 13 is inserted between the chip sucking mechanism 12 and water cooling plate 14, so the generated heating value of the element 13 is absorbed by a heat exchanger 15 to perform stable inspection for a long time over a wide -20 - 100°C temperature range. Further, a heat insulating spacer 17 cuts off heat conducted to a positioning mechanism 16. Also, the water cooling plate 14 and heat exchanger 15 are used to preclude dew condensation on a radiation side when the mechanism 12 is exposed to high temperature and also prevent the element from breaking when the mechanism 12 is returned to room temperature from the high temperature. Thus, laser characteristics at the high temperature above element temperature- threshold temperature can be evaluated and a chip with excellent characteristics can be selected even in high-temperature operation, so the quality guarantee of the product can be improved. n COPYRIGHT: (C)1991,JPO&Japio |
