This document, which is in line with IEC/PAS 62435 relating to the management of obsolescence of electronic components, is first of all a practical guide to methods of long
duration storage (more than 5 years) which summarizes the existing practices in the industry.
The application of the approach proposed in this guide in no way guarantees that the stored components are in perfect operating condition at the end of this storage. It only comprises a
means of minimizing potential and probable degradation factors.
Unless otherwise specified, the approach, as well as the methods presented apply to all families of electronic components:
− passive components, including quartz crystals, connectors and relays. However, components with "manufacturer’s" specifications showing an expiry date, or specific storage conditions, are excluded from this guide (e.g. primary cells, storage cells, etc...),
− encapsulated or non-encapsulated active components of a silicon [Si] or gallium arseenide [GaAs] technology,
− micro-electronic assemblies.
