15、eed to store electronic devices for long periods of time. Lifetime buys are commonly made to support production runs of assemblies that well exceed the production timeframe of its individual parts. This puts the user in a situation requiring careful and adequate storage of such parts to maintain the

16、 as-received solderability and minimize any degradation effects to the part over time. Major degradation concerns are Moisture, Electrostatic Fields, Ultra- Violet Light, Large variations in temperature, Air-Borne Contaminants, and outgassing. Warranties and sparing also present a challenge for the

17、user or repair agency as some systems have been designated to be used for long periods of time, in some cases for up to 40 years or more. Some of the devices needed for repair of these systems will not be available from the original supplier for the lifetime of the system or the spare assembly may b

18、e built with the original production run but then require long term storage This document was developed to provide a standard for storing electronic devices for long periods of time. For storage of devices that are moisture sensitive but that do not need to be stored for long periods of time, refer

19、to JESD-033. 11 Copyright Government Electronics & Information Technology Association Provided by IHS under license with GEIA Not for ResaleNo reproduction or networking permitted without license from IHS-,-,-GEIA- STD-0003 1 PURPOSE This document is generated to provide an industry standard for Lon

20、g 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 semiconducto

21、rs and packaged electronic devices, nothing in this standard precludes the storage of other items under the storage levels defined herein. 1.1 Scope 1.1.1 electronic, electro-mechanical (EEE) item, or assemblies using such items. This standard is intended to ensure that adequate reliability is achie

22、ved 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 regard

Unpackaged semiconductors are semiconductor wafer or dice. 1.2.3 would store electronic devices or unpackaged semiconductors. m. The user of this long

26、vel(s) per SecLkw 3.3 be specified. When invoked without specifying a level, Level 2 shall apply. When Level 2 is specified, it may be satisfied either with a portable storage container per S.:.or a fixed storage location per Yectioii 3.2.1. Level 4 may be used to meet Level 3 requirements.

No material shall be placed inside the container that is associated with outgassing (e.g. paper, cardboard, adhesives), even if this material was delivered as original packaging material from the
