RNS has a rich history of delivering high-quality cutting-edge technology on time and on budget.

We have been developing test fixtures for the Automated Test Equipment (ATE) market and distributing test probes for 30+ years. Our clients span the globe and many have been with us since the beginning. Here's why.

RNS: Where we started, where we're going

RNS International is a privately held company headquartered in Charlotte, NC. Founded in 1983, RNS launched as a test probe distributor for North America. Two years later, RNS began developing test fixtures for the Automated Test Equipment market. Since that time, RNS has become your best choice for ICT (In-Circuit Test) and FVT (Functional Verification Test) fixtures.


RNS is world-renowned in the electronics market for its highest-quality standards, experience, competence and commitment to the design and manufacture of exceptional test fixtures.


While specializing in custom fixtures for larger more complex circuit boards, we also provide support for all fixture requirements including Functional and Radio Frequency (RF) testing. Whether 5 or 5,000 test points, RNS builds to our customer specs and adds value through both service and support.

Two goals guide our day-to-day

1) 100% customer satisfaction

2) Delivering the best products to suit your needs.


We always ship a quality working product. Our workflow entails several steps to ensure the highest possible quality by checking each individual part during production. Quality Control (QC) at RNS begins in the Engineering Department and goes through the entire production process. Learn more about our mission.
