Pyramid Probe Card FAQs
Cores FAQ
Find your answers to core questions such as: Can I use a single RF line with an isolated ground as a balanced pair?What are the inductances for GP membrane ISS loads? What is the dielectric constant of the polyimide in PPD cores? Answers to these questions and more in the Cores FAQ.

Boards FAQ
Find your answers to board questions such as: Can I get a custom circuit board with OSSP connectors? Where can I get an edge-connector for my 48- or 70-finger Pyramid Probe Card? The AC lines are routed to "ground signal square pins" on the board. Which ground is this, and is there a specific connector that matches the pins?

Wafers FAQ
Find your answers to wafer questions such as: Do the AC signal lines require a signal and ground contact on the wafer or just one pad? Some of our pads have a pitch of only X microns. Is this going to pose any problems?

One-Port VNA Calibrations
How do I perform VNA calibrations with my Pyramid ProbeTM cards? For one-port VNA calibrations, use short-open-load calibration coefficients for an equivalent Air Coplanar® (ACP) probe pitch and configuration (ground-signal-ground or ground-signal).
Two-Port VNA Calibrations
How do I perform VNA calibrations with my Pyramid Probe cards? Probe cards provide a challenge for two-port calibration. The fixed probe spacing, often with inconveniently oriented ports, makes it difficult to make an ideal thru calibration standard.
