Hermeticity Evaluation Testing

Problem Statement:

Leak testing per Mil-Std-883 only provides a single, one-time room ambient check of the integrity of the hermetic seal. The reality is, for most packages, the leak rate changes with time based on temperature, pressure, and ambient humidity conditions. Often times perfectly good packages are scrapped, while other times apparently good packages are released into the field only to fail catastrophically due to excessive amounts of moisture.

The Solution:

Mount a miniaturized microelectronic sensor inside the package and monitor real time moisture ingress as a function of changing external ambient conditions. Use this data to determine the right amount of moisture protection for your product and end-use moisture environment. Develop real life models to predict moisture content as a function of time.
