Custom Burn-In Test Sockets for HAST, High Temp, and Reliability Testing
Engineered for Consistent Results in Harsh, High-Stress Environments
US-made burn-in test sockets engineered for high-performance and reliability in extreme testing environments. Our solutions are built to handle harsh conditions including high temperature, high humidity, and HAST (Highly Accelerated Stress Test) applications. Constructed with resilient materials and premium stainless steel-based spring pins, these sockets ensure long-term performance you can trust across packaged ICs and custom PCB modules. Built specifically for your device and fully compatible with your existing oven systems, our innovative temperature-sensing socket solutions maximize testing accuracy while minimizing downtime. Trust our American-made quality for your most demanding burn-in testing needs.

▪ Unmatched Durability
Our burn-in test sockets are engineered to withstand extreme temperatures, from the standard 120°C to over 200°C. They deliver reliable performance in the most demanding HAST and reliability testing environments.
▪ Space-Efficient Designs
Test more devices per burn-in board. Our semi-custom sockets are available in both single-site and multi-site configurations to optimize board real estate and support higher volume burn-in testing.
▪ Device-Level Temperature Monitoring
Integrated thermal sensors and heat spreaders make direct contact with the DUT, providing faster and more accurate temperature readings at the device level compared to ambient oven sensors. Ideal for controlled burn-in board designs.
▪ Ease of Service
Our compression mount test sockets include replaceable stainless steel spring pins rated for tens of thousands of insertions. This ensures long-term serviceability as socket contacts wear through repeated use.

Semi-Custom Footprint Design Options
We provide custom burn-in sockets that are compact and efficient, designed to save space on the burn-in board. These sockets are perfect for standard packaged IC's, WLCSP devices, and complex modules, offering a range of value-added design options to meet your specific needs. Our burn-in sockets are customized to accommodate advanced IC packages and PCB modules, including ASICs (Application-Specific Integrated Circuits), SoCs (Systems on Chip), MCMs (Multi-Chip Modules), and FPGAs (Field-Programmable Gate Arrays).
Multi-Site Burn-In for IC packages
Just about every test socket RTI manufactures can be used for standard burn-in, including our multi-site strip and test sockets. The ability to load multiple devices in a single socket reduces overall socket cost-per-site while maximizing the number of concurrently tested devices per board. These sockets feature clip on removable lids with open or closed top over each test site. Explore additional multi-site customization options and determine the optimal number of test sites per socket by talking to an RTI engineer today.
Advanced Burn-In Socket Materials
Our test sockets are made from high-performance materials, enabling them to reach high temperatures with short ramp-up times while maintaining continuous performance. We utilize pogo pins with stainless steel springs and resilient body materials like ceramic to ensure durability and reliability in every test, including those above 200C.
Customization for Long-Term Performance
RTI's burn-in sockets are built for long-term performance, with a lifespan exceeding 25,000 insertions*. Our sockets are designed to withstand high temperatures and maintain stable contact resistance throughout the testing process. Features include:
- High-temp burn-in sockets rated for temperatures of ≥200˚C.
- Traditional burn-in sockets rated for temperatures of +120˚C.
- Individually serviceable pogo pins and components for easy maintenance and extended use.
- Innovative design options tailored to meet unique testing requirements, including cartridge-based socket solutions for WLCSP burn-in.
*Actual lifespan is dependent on the cleanliness of the test environment, adherence to recommended ramp-up and ramp-down times, and careful handling by operators.
Fully Custom Footprints for Burn-In Excellence
Not all devices are created equal, yet all devices need to undergo rigorous burn-in reliability testing. RTI's fully custom test sockets for burn-in can include lateral contacts to hit test points on the side of the DUT. They can be customized in scale, down to <1 cubic centimeter. They can even integrate RTD sensors, heat spreaders, and thermocouples into the socket body or lid for DUT level temperature monitoring.
