20220099729 | AUTOMATED TESTING MACHINE WITH DATA PROCESSING FUNCTION AND INFORMATION PROCESSING METHOD THEREOF - An automated testing machine with data processing function and an information processing method thereof are introduced. The automated testing machine includes a test head for testing more than one device under testing (DUT), and the test head further includes a test processing unit for providing more than one electrical test signal to the DUTs and conducting a processing and analyzing on more than one electrical feedback data fed back from the DUTs, so as to generate analysis result information. With the test processing unit capable of conducting data processing directly provided in the test head, signals obtained from the DUTs can be directly analyzed and processed to enable increased data processing efficiency, increased convenience in use and reduced costs of the automated test machine and the information processing method thereof. | 2022-03-31 |
20220099730 | TEST SOCKET AND TEST APPARATUS HAVING THE SAME - The present disclosure discloses a test socket according to the present disclosure including an inelastic electro-conductive housing formed of an inelastic electro-conductive material and provided with a plurality of housing holes passing therethrough in the thickness direction, each housing hole being formed at a position corresponding to each terminal of a device under test; and an electro-conductive part formed to have a configuration in which a plurality of electro-conductive particles are oriented in the thickness direction in an elastic insulating material, and comprising an electro-conductive part for grounding, an electro-conductive part for signal, and an electro-conductive part for power disposed in the housing holes, respectively, the electro-conductive part for signal and the electro-conductive part for power being insulated by an insulating layer. | 2022-03-31 |
