Infinity coaxial RF probe contact for crosstalk measurements

FormFactor · Geometric and electrical metrology

Purpose: Interposer crosstalk comparisons must separate device coupling from probes and fixtures.
Technical approach: Infinity uses thin-film/coaxial structures to confine fields and contact exposed RF pads.
Scope of use: For accessible test structures with matching pad layout, pitch, connectors and frequency band.
Limitations and open questions: These evaluation considerations are compiled by BLNKK from public information. They are not supplier guarantees or a mandatory submission checklist.
Scope and limitations
Probes alone do not acquire multiport S-parameters or diagnose crosstalk. Contact, probe coupling and de-embedding affect results; other Infinity models’ frequency specifications do not transfer.
What to prepare
BLNKK suggests preparing pad drawings, frequency band, port count, instrument/cable configuration, calibration structures and intended reference planes.
Confirm with the supplier
Confirm topology, pitch, contact force/marks and usable bandwidth, together with calibration, de-embedding and repeatability checks.
Public evidence: The product page describes nickel-alloy tips, probe configurations and reduced unwanted coupling.
