QA Technology offers a comprehensive range of test probes and hyperboloid contacts. Our spring loaded test probe products range from in-circuit and functional test (ICT / FCT probes) to high current probes, as well as bare board probes and ATE interface probes. Our patented X Probe Socketless series allows smaller package design while offering all of the benefits of a larger test probe. All our product series offer a wide selection of probe point styles tips to meet your PCB test needs.

In-circuit and Functional Test Probes

For in-circuit or functional testing of loaded or bare printed circuit boards. QA offers an extensive line of products, ranging in size from .025 [0.63] to .187 [4.75] center spacing, with a wide selection of tip styles and spring forces for your specific application.

X Probe Socketless Series

The X Probe® Socketless design, eliminating the socket from the system, allows a more robust probe to be mounted on closer centers compared to a standard probe and socket system.  Our X Probe® products are also used in the same applications as our in-circuit and functional products.

High Current Probes

High conductivity, proprietary metal alloys and platings allow this series of probes to carry increased electrical currents compared to standard probes.

Double Ended Probes (BGA)

Designed for 0.35, .80  & .100 mm to be used in standard and custom socket applications.

ATE Interface Probes

Designed for interfacing the electromechanical contacts of a tester to the test fixture.

Hyperboloid Contacts Catalog

High performance hyperboloid contacts provide a robust and flexible connector system with the flexibility to accommodate standard and custom applications.
