Test Chamber Fixtures

Precision-engineered test chamber fixtures designed to withstand thermal cycling, environmental stress, and extreme temperature conditions while maintaining flawless electrical connectivity.

Environmental & Thermal Chamber Test Fixtures

Environmental test chamber fixtures are specialized mounting nests, holding rigs, and high-temperature interfaces designed to secure electronic assemblies inside environmental test chambers. Engineered to maintain structural integrity under extreme thermal cycling, humidity, and atmospheric pressure changes, these custom fixtures minimize dead air space surrounding the Device Under Test (DUT) to accelerate thermal transfer and improve test accuracy.

Primary Categories of Chamber Test Hardware

Fixtronic designs and fabricates environmental fixtures configured for specific qualification regimes:

  • Environmental & Thermal PCB Test Rigs

    High-temperature functional and bed-of-nails interface assemblies built to withstand continuous operational sweeps across extreme thermal ranges (e.g., -40°C to +125°C) and elevated humidity without warping or degrading pin alignment.

  • Hermetic & Pressure Leak Testing Nests

    Custom drawer-style enclosures and sealed cavities engineered to clamp components securely during pressurized air or tracer-gas leak detection sweeps.

  • HALT & HASS Screening Fixtures

    Heavy-duty test interface plates optimized for Highly Accelerated Life Testing and Highly Accelerated Stress Screening, built to endure rapid temperature change rates and multi-axis vibration profiles.

  • Battery & High-Energy Hazard Enclosures

    Reinforced safety fixtures compliant with EUCAR hazard classifications (up to Level 7), engineered to isolate and contain thermal runaway events during stress validation of energy storage modules.

  • Mechanical & Material Stress Grips

    Specialized compression plates, peel fixtures, and shear rigs designed for tensile and mechanical testing inside thermal conditioning cells.

Engineering Standards & Material Selection

Designing hardware for chamber operation requires strict attention to thermal expansion coefficients and physical resilience:

  • Thermal-Grade Materials

    Machined using specialized composite materials (such as high-temp G10/FR4, polyimide derivatives, and treated aluminum alloys) that resist thermal shock, outgassing, and moisture absorption.

  • Volumetric Efficiency

    Milled to tightly match the physical outline of the DUT, reducing internal air volume to allow faster thermal stabilization and higher measurement sensitivity.

  • Universal Chamber Compatibility

    Mounting interfaces engineered to fit standard environmental chambers and universal testing frames, featuring flexible mounting brackets and pass-through cable seals.

  • Regulatory Compliance

    Built to satisfy rigorous aerospace and automotive stress testing standards, including MIL-STD-810H and AEC-Q100/200 guidelines.
