-
New tip architecture enables support for narrower pitches (e.g. 25um)
-
Advanced mechanical design combined with small contacts enables probing on smaller pads/pitches and improves durability and robustness

-
Ease of use – Less experienced operators can perform an RF calibration up to 500 GHz by simply pushing a button. This reduces the need of experienced users full time on each system.
-
Reduced Soak Time – The system will automatically re-align the probes to the pads if they drift from alignment. This reduces test time and increases throughput.
-
Unattended Use – Measurements can be left running over night or the weekend, testing all devices on the wafer, and at different temperatures without the need of an operator.
-
Calibration Monitor and Re-calibration – System will
continuously monitor calibration drift, and automatically re-calibrate the system should the drift exceed a predefined limit.
