climatichumiditytemperature

The Environmental Stress Screening Test Chamber (ESS) is a specialized reliability testing equipment designed to accelerate the exposure of potential defects in products. By applying environmental stresses such as temperature cycling, vibration, and humidity, it quickly triggers early failures, thereby improving the quality of products upon leaving the factory. Technical Specifications HALT HASS Chamber of Patent Number: CN201520670413.0 HALT Test: Maximum Temperature: +140°C to +170°C (Requires rapid heating, rate ≥ 60°C/min) Minimum Temperature: -70°C to -100°C (Requires rapid cooling, rate ≥ 50°C/min) HASS Test: Temperature Range: -55°C to +125°C (Typical standard for electric vehicle batteries) Temperature Change Rate: ≥ 40°C/min (Simulates extreme environmental transient changes) HALT: Above 50Grms (Finds potential defects) HASS: 20-30Grms (Production screening intensity) Temperature and Vibration Synchronization: Must combine vibration with high/low temperatures (e.g. -40°C + 20Grms) HALT: Each temperature/vibration step lasts 10-15 minutes until failure. HASS: Typical cycle: 4-6 hours per cycle, including rapid temperature change + vibration (e.g. 4 temperature cycles + vibration) Features of product development Vibration type: 6-degree-of-freedom (6DoF) multi-axis random vibration Frequency range: 5Hz to 10kHz (covering road vibrations and mechanical resonance points) Vibration table control: Industrial 4.0 real-time data feedback, supports PSD (power spectrum density) custom curves Humidity control (optional): 5%RH to 95%RH (for battery sealingity testing) Real-time monitoring of parameters such as temperature, vibration, current, voltage, etc., with sampling frequency ≥ 1kHz. Support for IoT protocols (such as OPC UA, MQTT) and connection with MES/PLM systems. Pre-set test templates (such as Volkswagen 80000 or BMW GS 95024 standards). AI algorithm predicts failure modes (such as analysis of battery thermal runaway precursors) Battery-specific protection: explosion-proof design (ATEX standard), gas emission system (to prevent electrolyte leakage hazards) Additional Options · Reliability Testing: highly accelerated stress screening test for electronics, automotive components, aerospace systems, and medical devices. · Failure Analysis: Identifies design weaknesses and manufacturing defects. · Production Screening: Ensures product robustness via HASS (Highly Accelerated Stress Screening) in mass production. · R&D Validation: Validates product lifespan under extreme conditions (temperature, vibration, humidity).
