Need faster, more reliable humidity testing for semiconductors and packaged devices? Transform weeks of testing into days with Element's HAST services. Our expert-designed test plans ensure product safety while accelerating time to market. Get A2LA-accredited, ITAR/EAR-compliant testing for commercial and government applications—with comprehensive data and reduced costs through our customized approach.
What is Highly Accelerated Stress Testing (HAST)?
HAST testing is an advanced environmental simulation method that provides a more efficient alternative to traditional humidity testing most commonly used for testing semiconductors. By elevating temperatures and increasing pressure, At Element, we simulate long-term humidity conditions to observe the same failure mechanisms in days rather than weeks. Our testing supports multiple applications including semiconductor reliability, packaging validation, transportation testing, and shelf-life programs. We provide efficient and reliable testing for your non-hermetic and packaged devices, delivering comprehensive safety data through our accredited facilities.
What Can Element Offer You For Highly Accelerated Stress Testing (HAST)?
Components and materials we test
From critical semiconductor components to complex packaged devices, we provide comprehensive HAST testing across a diverse range of materials and components. Our testing capabilities cover non-hermetic packages, solid-state devices, and transportation packaging materials. Whether you're developing new semiconductor technology or validating packaging reliability, our expertise ensures thorough assessment of your materials under accelerated stress conditions.
Key tests offered
Our HAST testing program delivers precise environmental simulation by observing the same failure mechanisms as traditional humidity testing but in days instead of weeks. Our experts help you design test plans that meet your product's unique needs while reducing time and cost associated with full-scale testing.
- Temperature elevation testing
- Pressure increase simulation
- Humidity penetration analysis
- DC voltage bias testing (continuous and cycled)
- Long-term humidity simulation
- Moisture penetration assessment
Methods and solutions offered
We develop customized test plans tailored to your specific product requirements and development stage. Our methodology supports every phase of your product lifecycle, from initial research through design validation to prototype evaluation and final qualification. By combining elevated temperatures and pressure with precision monitoring, we deliver reliable results that help you make informed decisions about your product's performance and durability.
Our labs help determine reliability of non-hermetic, packaged and solid-state devices in a variety of humid environments. Along with temperature and humidity conditions, a bias (DC voltage – continuous or cycled) can accelerate the penetration of moisture, to provide results in less time.
