This document is generated to provide an industry standard for Long Term Storage (LTS) of electronic devices by drawing from the best long term storage practices currently known. For the purposes of this document, LTS is defined as any device storage for more than 12 months but typically much longer. 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.
Packaged Electronic Devices. Electronic Devices are defined as any packaged electrical, electronic, electro-mechanical (EEE) item, or assemblies using such items. This standard is intended to ensure that adequate reliability is achieved for devices in user applications after long term storage. Users are encouraged to request data from suppliers to this specification that demonstrates a successful storage life requested by the user. This standard is not intended to address built-in failure mechanisms that would take place regardless of storage conditions.
Unpackaged semiconductors. Unpackaged semiconductors are semiconductor wafer or dice.
User. The user of this long term storage standard may be any organization or entity who would store electronic devices or unpackaged semiconductors.
