Highly Accelerated Life Testing Machine (HAST)

1. Core Mission & Industry Significance

Highly Accelerated Life Testing (HAST) is a vital approach for gauging the reliability and service life of electronic components, semiconductors, and materials under extreme environmental stresses (temperature, humidity, voltage). By intensifying these stresses, HAST condenses years of real - world usage into weeks or months, pinpointing failure modes, wear mechanisms, and early - life failure risks—essential for product design refinement and quality assurance.

2. Technical Compliance & Precision Control

Our HAST adheres to international benchmarks: IEC 60068 - 2 - 66 (Environmental Testing) and JEDEC Standards (A110 for Unbiased Humidity, A118 for Biased Humidity). It supports three control modes:

• Unbiased Humidity - Temperature: Maintains stable humidity without direct voltage bias on samples.

  
  

• Unbiased Temperature Rise: Focuses on temperature increase with minimal humidity interference.

  
  

• Biased Humidity: Simulates real - world scenarios with applied voltage to test dielectric breakdown or corrosion.

  
  

Temperature ranges from 105–150°C (covering 100%, 85%, and 65% RH conditions), humidity spans 65–100% RH, and pressure adjusts between 0.019–0.208MPa. This precision ensures tests replicate actual operating environments, from consumer electronics to aerospace components.

3. Structural Design & Material Quality

Featuring a single - chamber layout, the HAST optimizes space with internal dimensions (e.g., Φ420×D485mm for a 67L capacity in the UHAST - 450A model) and a 340×D475mm test area. The inner chamber uses SUS316L stainless steel—corrosion - resistant and easy to clean—for repeatable, contamination - free tests. A built - in water supply system (with SUS316L water tank) ensures stable humidity during long - term trials.

4. Intelligent Safety & Automation

Safety is a top priority. The HAST has three protective layers:

• Electrical Safety: Over - current, over - voltage, and short - circuit protection prevent hardware damage.

  
  

• Thermal/Hydraulic Safety: Over - temperature shutdown, leak detection, and emergency venting protect against overheating and humidity spikes.

  
  

• Mechanical Safety: Interlocked doors and pressure - relief valves ensure operator safety during high - stress cycles.

  
  

Automation improves efficiency:

• Automatic Door Operation: Doors open after testing to speed up cooling, reducing cooldown time by 40%.

  
  

• Remote APP Control: Program up to 50 test steps per sequence, monitor real - time data, and save results to USB via a mobile app.

  
  

• Self - Cleaning System: Automated flushing of the cooling chamber prevents condensation buildup, eliminating cross - contamination between tests.

  
  

5. Wide Application Range

From R & D labs to quality control departments, the HAST serves multiple sectors:

• Semiconductors: Test ICs, transistors, and sensors for moisture - related failures.

  
  

• Electronics: Validate PCBs, connectors, and displays under high - temp/high - humidity.

  
  

• Automotive: Evaluate ECUs, sensors, and wiring harnesses for durability in harsh climates.

  
  

• Materials Science: Examine polymers, coatings, and composites for degradation resistance.
