SAE GEIASTD0003A

This document provides an industry standard for Long Term Storage (LTS) of electronic devices by drawing from the best long term storage practices currently known. LTS is defined as any device storage for more than 12 months but typically allows for much longer (years). While intended to address the storage of unpackaged semiconductors and packaged electronic devices, nothing in this standard precludes the storage of other items under the storage levels defined herein. This standard is not intended to address built-in failure mechanisms (e.g., tin whiskers, plating diffusion, and intermetallics) that would take place regardless of storage conditions An extensive review of the first release of the Long Term Storage (LTS) document was accomplished to strengthen the document as a standard. The primary areas of enhancement were to the long term storage control requirements and the appendixes with guidelines for executing these requirements. Updating of the storage level protection was clarified to improve the decision flow to which primarily electronic devices are to be stored. Desiccant requirements were clarified and guidelines were added to assist in selecting the desiccant.
