What is it?

The sources describe the Electroglas EG4|200 as a wafer prober for leading-edge, multi-die, and bumped 200mm wafer applications. It is described as featuring a probe-centered Z-drive with up to 150 kilograms of Z-force. A related EG4|200e variant is identified as a wafer prober for ultra-low-noise probing, parametric test, e-test, and wafer acceptance.
