Custom Test Chamber Fixtures engineered with climate-resistant materials and robust wiring interfaces to deliver accurate, repeatable testing under extreme temperature and environmental conditions.
Test Chamber Fixtures (TCF) are rugged, specialized testing assemblies designed to operate inside environmental, thermal, and climate-controlled test chambers. During product development and quality assurance, electronic assemblies such as printed circuit board assemblies (PCBAs) must undergo extreme environmental stress screening (ESS) to verify structural and electrical integrity. Test Chamber Fixtures provide the crucial bridge between the Device Under Test (DUT) inside the chamber and the external instrumentation monitoring its performance.
Engineered to endure severe atmospheric conditions, these fixtures maintain reliable electrical contact and mechanical stability while subject to rapid thermal cycling, extreme temperature highs and lows, humidity variations, and environmental vibration. By isolating signal connections from harsh internal chamber conditions, Test Chamber Fixtures ensure that environmental stress testing yields accurate, repeatable, and uninterrupted diagnostic data.
Thermal & Environmental Resilience
Constructed from high-grade, thermal-resistant materials engineered to withstand severe temperature swings during burn-in and thermal shock testing without warping, degrading, or losing dimensional accuracy.
Built with specialized coatings, sealed wiring interfaces, and humidity-resistant plates designed to prevent condensation, oxidation, and insulation breakdown in high-moisture testing environments.
Engineered to maintain precise probe pressure and alignment even under continuous thermal expansion and contraction cycles.
Interface & Testing Integration
Features custom thermal-sealed cable harnesses and feedthrough connectors that route test signals cleanly out of the sealed chamber to external measurement equipment without disrupting chamber insulation.
Tailored to securely clamp various PCBA form factors, modules, and sub-assemblies inside compact or large-scale environmental chambers
Suitable for a wide range of reliability assessments, including thermal cycling, humidity exposure, operational stress screening, and long-term product burn-in protocols.
At Fixtronic, we design and manufacture custom bed-of-nails test fixtures tailored to your PCBA testing needs. Combining extreme precision with fast lead times and competitive pricing, we help keep your production running without downtime.
