FormFactor - Cascade High Current Probe - Test power devices on wafer with high-performance and low-contact resistance on smaller pads
- Enables wafer probing up to 100 A pulsed and 10A DC
- Innovative multi-fingertip design provides even distribution of current
- Supports up to 500 V
- Replaceable Tungsten probe tips
- Temperature range of -60°C to 300°C
- Minimal contact resistance at the pad-tip junction to reduce heating during measurements, with fewer probe marks
- Prevents against thermal runaway
- Measure devices on wafer at higher currents than ever before
- Small scrub minimizes damage to aluminum pad
- Small footprint – tip fits on a 1 mm pad
Designed specifically for testing power devices on wafer, the HCP probe reduces probe and device destruction at high currents by minimizing contact resistance at the wafer-to-probe interface to prevent device heating at the tip. The innovative multi-finger design distributes the current over multiple contact points at the tip and is joined by a single heatsink which pulls heat from the probe tip.
