Infinity Probe - Coaxial
FromFormFactor, Inc.
Ideal for device characterization and modeling, Infinity probe combines extremely low contact resistance on aluminum pads with unsurpassed RF measurement accuracy for highly reliable, repeatable measurements. Proprietary thin-film and coaxial probe technology reduces unwanted couplings to nearby devices and transmission modes.
- Lithographic thin-film construction
- Excellent crosstalk characteristics
- Non-oxidizing nickel alloy tips
- Innovative force delivery mechanism
- 40GHz, 50GHz, 67GHz, 110GHz and 145GHz connectors available
- GSG, SG, GS, GSGSG, GSSG, SGS configurations
- 50 to 250 µm pitches (other pitches available on request)
- High current version (2 A) available
Advantages
- Superior field confinement reduces unwanted couplings to nearby devices and transmission modes
- Superior measurement accuracy and repeatability
- Small scrub minimizes damage to aluminum pad
- Typical contact resistance < 0. 05 Ω on Al, <0.02Ω on Au
- Save valuable wafer space and reduce pad parasitics by being able to shrink pad geometries to 25 x 35 µ m (best case)
