Used ELECTROGLAS / EG 4090u #293603740 for sale

ELECTROGLAS / EG 4090u is a wafer prober from EG. It offers a highly accurate and reliable wafer probing solution that is suitable for high-volume production. EG 4090u prober uses a standard XY automated prober motion equipment and a high-precision vertical elevating stage to accurately place and align a wafer onto the device under test (DUT). The prober is also equipped with a fully integrated load cell that enables precise positioning and force control of the wafer on the DUT. This allows for accurate wafer mapping and alignment up to 0.5 microns of accuracy. Additionally, the load cell's integral touch-sensing mechanism enables the probe arm to assess contact of the wafer on the DUT, providing the user with valuable feedback to ensure contact is achieved during the probing cycle. ELECTROGLAS 4090 U also provides an advanced vision system for image capture, analysis, and comparison. This enables high-precision inspection of pattern recognition across various levels of design complexity. The vision unit consists of CCD cameras and integrated illumination, both with bright LEDs, enabling clear and sharp imaging to aid the user during programming and operation. The prober has a standard 8.4″ diagonal contact area and a tip indexing machine for selecting tips ranging from 0.4 to 4 mm diameter. It also comes with a wide variety of other features such as multiple test contact covers, shielded probe arms and tips, and a programmable manual/automatic Z-lift feed rate. ELECTROGLAS / EG 4090 U can probe wafers of thicknesses up to 30mil or 0.76mm, as well as substrates up to 10″-15″ in diameter. 4090 U prober is compatible with all standard prober control software, making it suitable for most testing and probing applications. Furthermore, it has an IP protection rating of IP50, ensuring sufficient protection against dust and other environmental factors. Overall, EG 4090 U prober is designed for performance, reliability, and accuracy. Its sophisticated technologies enable high-precision wafer probing for various applications, making it an excellent choice for semiconductor and testing laboratories.
