Can We Really Prove an Ultra-Low Leak Rate? Rethinking Hermeticity of Electronic Packages

Hermeticity is often considered a straightforward pass/fail metric, yet when it comes to ultra-low leak rates in critical applications—such as medical implants, space electronics, and MEMS devices—standard testing methods may not tell the full story.

This keynote will break down the fundamentals of hermeticity, exploring the three key leak paths: leak channels, permeation, and outgassing. We’ll take the theory of leak rate quantification and show how it translates into real-world measurement challenges, particularly for low-cavity volume packages with stringent vacuum requirements.

But can we truly prove an ultra-low leak rate? External measurement techniques have well-documented limitations, and yet they remain the industry standard. We’ll discuss the gaps in current test methodologies, the challenges in meeting stringent performance requirements and how in-situ approaches offer a path to more meaningful validation.

Attendees will leave with a deeper understanding of leak rate quantification and why design-stage consideration of hermeticity testing is crucial for ensuring performance over time. If you assume standard tests are enough, this talk might just change your mind.
