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.
