Reduced Footprint Bypass Capacitor on Pyramid Probe® Thin Film

Shrinking geometries and increasing performance requirements are driving the need for testing with reduced parasitics and cleaner power supplies. One of the unique features of Pyramid Probes is the ability to place components on the thin film closer to the DUT than with other probe technologies. This tech brief describes the reduced footprint structure to attach bypass caps (or any shunt component).

Cleaning Pyramid Probe Cards

Pyramid Probe cards may collect contaminants that make cleaning necessary. The cleaning frequency and intensity required to keep a Pyramid Probe operating at its peak efficiency are primarily related to the probing environment. Because of this, the exact formula for cleaning Pyramid Probe cards must be determined individually for each application. This document starts with some general comments about cleaning Pyramid Probe cards and the contaminants that may be found in probing environments. The document th

Mechanical Differences Between Pyramid and Cantilever Probes

Pyramid ProbesTM provide the best electrical performance of any probe technology, thanks to their use of thin film to route controlled impedance lines and the ability to place bypass capacitors close to the device under test. One of the less well known advantages of Pyramid probes, however, is the mechanical stability of probe tips in the x-y plane. Due to differences in the ways cantilever probes and Pyramid probes are constructed, Pyramid probes are more positionally accurate than cantilever probes, and r

Gauge Tool Study on Use of Torque Wrenches for CMI Pyramid Probe Core Tightening During FTL Measurements

The method of tightening a Pyramid Core into a probe card has been studied. Data shows that using a torque driver results in seven times more repeatable first to last over travel (FTL), and 25% smaller FTL. It is recommended that all cores be torqued to remove FTL variation using a specified process.
