FormFactor - Cascade WPH Probe - Multi-contact DC probe with full-radius needles
- Full-radius, nickel-plated tungsten needles
- Power bypass inductance: 16 nH
- Supports collinear and non-standard needle configurations
- Support up to a maximum of 12 ceramic blades DC needles / contacts
- Ideal for probing the entire circuit for functional test
- DC probes can provide power or slow logic to circuit under test
The WPH probes feature up to 12 ceramic-bladed, nickel-plated, tungsten needles with a 2 x 12 square pin cable interface. The circuit board has been laid out such that both series and shunt components can be added to the signal path of each needle.

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.
