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.
