Overview
The OK-PCT Series High-Pressure Accelerated Life Aging Test Chamber is an engineered environmental stress test system designed for reliability validation of hermetic and semi-hermetic components under elevated temperature and saturated steam pressure conditions. It operates on the principle of accelerated moisture ingress testing—leveraging the thermodynamic relationship between temperature, pressure, and water vapor saturation—to simulate years of field exposure in days or weeks. Unlike conventional thermal cycling or humidity chambers, the OK-PCT applies controlled super-saturated steam environments at pressures up to 200 kPa gauge (302 kPa absolute), enabling rapid diffusion of moisture through micro-defects in seals, encapsulants, and solder joints. This makes it essential for early-stage design verification in aerospace, automotive electronics, medical device packaging, and high-reliability PCB assembly—where latent failure modes such as corrosion, delamination, popcorning, and wire bond degradation must be identified prior to qualification release.
Key Features
- 7-inch industrial-grade touchscreen HMI with embedded PID algorithm for precise saturated steam temperature control (±0.5 °C stability at setpoint)
- Stainless steel cylindrical inner chamber conforming to ASME BPVC Section VIII Div. 1 structural safety requirements for pressure vessels
- Radially contoured inner liner geometry to minimize direct impingement of latent heat from condensing steam onto test specimens
- Pressure-synchronized door locking mechanism: internal overpressure enhances gasket compression force, improving seal integrity and extending gasket service life beyond conventional clamp-style designs
- Auto-refill system with ultrasonic water level sensing and dual-stage low-water alarm (visual + relay output)
- Integrated safety architecture including ASME-certified spring-loaded pressure relief valve (set at 210 kPa gauge), independent overtemperature cutout (150 °C mechanical backup), and real-time pressure/temperature interlock monitoring
- Optimized water economy: single fill supports uninterrupted operation for up to 200 hours under standard test profiles (e.g., JESD22-A102, MIL-STD-883 Method 1008)
Sample Compatibility & Compliance
The OK-PCT accommodates a broad range of sample geometries—including IC packages (QFN, BGA, CSP), multi-layer PCBs, LED modules, MEMS sensors, implantable electronics housings, and automotive power modules—within its cylindrical test volume. Its uniform steam distribution and absence of forced convection eliminate localized hot/cold spots that could skew failure statistics. The chamber complies with key industry test standards including JEDEC JESD22-A102 (Pressure Cooker Test), AEC-Q200 stress requirements for passive components, MIL-STD-883 Method 1008.3 (Moisture Resistance), and IEC 60068-2-66 (Test Db: Damp Heat, Steady State, High Pressure). Optional data logging and audit trail capabilities support GLP/GMP environments aligned with FDA 21 CFR Part 11 requirements when paired with validated software.
Software & Data Management
The embedded controller records time-stamped temperature, absolute pressure, and water level at user-defined intervals (1–60 seconds). Raw data exports via USB to CSV format for traceability and statistical analysis (Weibull, Arrhenius modeling). Optional Ethernet interface enables remote monitoring, alarm notification via SMTP/SNMP, and integration into centralized MES or LIMS platforms. All calibration parameters are password-protected and logged with operator ID and timestamp—supporting ISO/IEC 17025 documentation needs for accredited laboratories.
Applications
- Qualification of moisture-sensitive devices (MSL 1–6) per IPC/JEDEC J-STD-020
- Accelerated life testing of conformal coatings and potting compounds
- Hermeticity validation of medical sensor housings and drug delivery cartridges
- Failure mode analysis of solder joint reliability under thermo-hygro-mechanical stress
- Process window development for reflow, molding, and encapsulation steps
- Reliability screening of automotive ADAS radar modules and battery management ICs
FAQ
What test standards does the OK-PCT support out-of-the-box?
It natively executes JEDEC JESD22-A102, MIL-STD-883 Method 1008.3, and IEC 60068-2-66 protocols. Custom profile programming allows adaptation to proprietary OEM specifications.
Is the chamber suitable for testing lithium-ion battery cells?
No. The OK-PCT is not rated for flammable or volatile sample testing. Battery safety testing requires specialized explosion-proof enclosures meeting UL 1642 or UN 38.3 requirements.
Can the chamber operate continuously for 200 hours without manual intervention?
Yes—provided initial water volume meets specification and ambient supply voltage remains within tolerance. The auto-refill system maintains minimum reservoir level during extended runs.
Does the system include NIST-traceable calibration documentation?
Factory calibration certificates (temperature, pressure) are provided with each unit. On-site calibration services with NIST-traceable standards are available as an add-on option.
What maintenance is required between test cycles?
Routine tasks include weekly inspection of gasket integrity, monthly descaling of the steam generator using approved citric acid solution, and quarterly verification of relief valve setpoint accuracy.
