SPRING LOADED TEST PROBES

IN-CIRCUIT/FUNCTIONAL (ICT/FCT) TEST PROBES

For in-circuit or functional testing of loaded or bare printed circuit boards.

For higher circuit density; larger probes mounted on closer centers

High conductivity, proprietary metals to carry increased electrical currents.

For use as electromechanical contact between fixture and tester.


DOUBLE ENDED PROBES

For use in testing semiconductor components, such as integrated circuits (IC) and ball grid arrays (BGA).

What's New

Introducing the New 5R Razor Tip

OCTOBER 2021

Available in our 039-25 and X31-25 series probes, enables a more effective contact on larger diameter vias. Cut with the same proven razor geometry as our 6R tip, but packaged on a ø0.025 [0.65] head diameter, it is designed for situations where other 039-25/X31-25 Series headless tip styles are too small to make a reliable contact.

New: Probe Identification

SEPTEMBER 2021

QA’s new laser markings mean that complete probe specifications can be easily identified to help with new fixture builds and to ensure exact replacement during regularly scheduled maintenance. We’re pleased to announce that this improved identification method is now featured on our 100-mil and X75 probe series.

New Video: How to Calculate Set Heights

JULY 2021

Our two new instructional videos show, step-by-step, how to calculate set heights. Setting sockets & termination pins at the correct height to achieve our probes' proper working stroke will increase first pass yields, reduce fixture maintenance costs, and improve performance and longevity.

New Video: How to Measure Probe Stroke in a Fixture

MAY 2021

Our new instructional video discusses how to ensure sockets, or X Probe termination pins, are set at the correct height for optimum probe stroke. This not only improves their performance and longevity, it also increases first pass yields and reduces fixture maintenance costs.
