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.

-
Best price per contact – typically over one million (1,000,000) touchdowns
-
RF/Microwave signal is shielded and completely air isolated in the probe body
-
Excellent performance in vacuum environments and temperatures as low as 4 K, or as high as 300°C
-
Highest impedance control with perfectly-symmetrical, MEMS-machined coplanar contact structure
-
Probe on any pad material with minimal damage
-
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.
