Access to Webinar: Near Hermetic Packaging, Session 2

Packages made from polymeric materials as opposed to traditional hermetic seals (i.e. metal, ceramic, etc.) require a different approach from a hermeticity testing standpoint. The problem is now one of moisture diffusion through the barrier and package interfaces, which is different than water vapor permeating a crack in a glass to metal interface. A brief review of the techniques and methods to evaluate a "non-hermetic" approach is presented along with a discussion of the pitfalls and issues of TM 1014 and TM 1018 as applied to a “near hermetic package.”

Session II:  Near Hermetic

A brief review of the techniques and methods to evaluate a "non-hermetic" approach is presented along with the fundamental theory.

Fick’s Law of Moisture Diffusion
WVTR, TGA, and moisture diffusion coefficients
Moisture Sensing (wired and wireless sensors)
How to qualify a “near hermetic “ package

NOTE:  Each session lasts about an hour and includes a complete set of course notes in PDF format.  Once the payment has been processed you will have two weeks to view the session.
