Used ELECTROGLAS / EG 4090u #293606447 for sale

ELECTROGLAS / EG 4090u is a prober designed for testing devices, such as high-density digital logic or mixed-signal integrated circuits (ICs). This prober comes equipped with an X-Y moving stage, allowing for precision placement of probe tip over terminated devices on a wafer under test. The base stage has a maximum travel of 150x150 mm and is manually adjustable to a step accuracy of 0.0001"/step. The prober also comes with a 16-bit digital encoder and a repeatability of 5 microns across its travel range. The prober can hold up to 100 different probe cards with a repeatability of 1 micron, and each card can hold up to 800 electrical probes. In addition, the prober includes an optional adaptive learning system, allowing the user to automatically identify which probes need to be applied to the wafer under test for receive the most accurate readings. The prober is controlled via an Ethernet connection, or through an optional PC software, where the user can enter probing parameters, such as contact force, contact resistance, accuracy, travel speed, and settling time. EG 4090u also has an optional automated tester. This tester can be used with a variety of test programs and languages, such as HSPICE, Verilog, and Verilog-A. This allows the prober to quickly identify and analyze any problems that occur in a testing wafer. ELECTROGLAS 4090 U also has a variety of safety features, such as a circuit shield, air breach sensing, mechanical overtravel protection, and an HV/LV disconnect circuit. These features help ensure the user's safety during the testing process and helps prevent any potential damage to the wafer under test. In conclusion, 4090u is a high-precision prober specifically designed for testing high-density digital logic or mixed-signal ICs. It is equipped with a highly adjustable X-Y moving stage, repeatable probe cards, and Ethernet control. The prober also has a variety of safety features and an optional automated tester to ensure problems are quickly identified and rectified.
