TRXCHUCK - Triaxial chuck
The triaxial chuck will allow ultra-low current measurement down to fA when used with specific micropositioners with trixial arm and hermetic box for light and shield isolation.

- It is composed of 3 parts of which the middle part can be polarized,
- A high-temperature version is also available when associated with a hot or tri-temp chuck
- Available for wafers up to 300 mm (12")
- The triaxial chuck typically replaces the standard chuck onto a manual or semi-automatic prober to perform low level current measurement.

PTG4 - Probe tip with Tungsten wire
The wire-tip combines a rigid body with a thin Tungsten wire of various diameters, the probe tip is then soft enough to avoid damaging the probing pad materials.

- Length of body 51 mm, Tungsten wire 3 to 5 mm
- Body diameter 0.51 mm, wire 5 to 125 microns
- Tip radius 0.1 to 5 microns
- Most popular references : PTG410, PTG422, PTG435, PTG4135

PTG20 - Tungsten probe tip
General purpose probe tip sharpened at one extremity, the body material (Tungsten) is strong enough to be bent into a variety of shapes.

- The standard application is probing on pads and/or internal lines
- Material Tungsten, length 38 mm, tip radius from 0.5µm to 100µm
- Nickel-plated option is available for body only (easy soldering), please add the suffix ''N'' to the P/N
