Electronic components - Long-term storage of electronic semiconductor devices - Part 3: Data
IEC 62435-3:2020 describes the aspects of data storage that are necessary for successful use of electronic components being stored after long periods while maintaining traceability or chain of custody. It defines what sort of data needs to be stored alongside the components or dies and the best way to do so in order to avoid losing data during the storage period. As defined in this document, long-term storage refers to a duration that can be more than twelve months for products scheduled for long duration storage. Philosophy, good working practice, and general means to facilitate the successful long-term-storage of electronic components are also addressed.
NOTE: In IEC 62435 (all parts), the term "components" is used interchangeably with dice, wafers, passives and packaged devices.
Composants électroniques - Stockage de longue durée des dispositifs électroniques à semiconducteurs - Partie 3 : Données
L'IEC 62435-3:2020 décrit les aspects du stockage de données nécessaires à la bonne utilisation des composants électroniques stockés après de longues périodes, tout en maintenant une traçabilité ou une continuité de possession. Elle définit les types de données à stocker avec les composants ou les puces et la meilleure façon de le faire en vue d'éviter une perte de données pendant la période de stockage. Comme défini dans le présent document, le stockage de longue durée fait référence à une durée pouvant dépasser douze mois, pour des produits destinés à être stockés pendant une longue durée. Les concepts, les bonnes pratiques et les moyens généraux de nature à faciliter la réussite d'un stockage de longue durée de composants électroniques sont aussi abordés.
NOTE: Dans l'IEC 62435 (toutes les parties), le terme "composants" fait référence aux puces, aux plaquettes et aux dispositifs passifs et encapsulés.

FOREWORD
1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of IEC is to promote
international co-operation on all questions concerning standardization in the electrical and electronic fields. To
this end and in addition to other activities, IEC publishes International Standards, Technical Specifications,
Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as "IEC
Publication(s)"). Their preparation is entrusted to technical committees; any IEC National Committee interested
in the subject dealt with may participate in this preparatory work. International, governmental and non-
governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely
with the International Organization for Standardization (ISO) in accordance with conditions determined by
agreement between the two organizations.
2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
consensus of opinion on the relevant subjects since each technical committee has representation from all
interested IEC National Committees.
3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
misinterpretation by any end user.
4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
transparently to the maximum extent possible in their national and regional publications. Any divergence
between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in
the latter.
5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity
assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
services carried out by independent certification bodies.
6) All users should ensure that they have the latest edition of this publication.
7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
members of its technical committees and IEC National Committees for any personal injury, property damage or
other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC
Publications.
8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
indispensable for the correct application of this publication.
9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of
patent rights. IEC shall not be held responsible for identifying any or all such patent rights.

INTRODUCTION
This document applies to the long-term storage of electronic components.
This document deals with the long-term storage (LTS) of electronic devices drawing on the
best long-term storage practices currently known. For the purposes of this document, LTS is
defined as any device storage whose duration can be more than 12 months for product
scheduled for long duration storage. While intended to address the storage of unpackaged
semiconductors and packaged electronic devices, nothing in this document precludes the
storage of other items under the storage levels defined herein.
Although it has always existed to some extent, obsolescence of electronic components and
particularly of integrated circuits, has become increasingly intense over the last few years.
Indeed, with the existing technological boom, the commercial life of a component has become
very short compared with the life of industrial equipment such as that encountered in the
aeronautical field, the railway industry or the energy sector.
The many solutions enabling obsolescence to be resolved are now identified. However,
selecting one of these solutions should be preceded by a case-by-case technical and
economic feasibility study, depending on whether storage is envisaged for field service or
production, for example:
• remedial storage as soon as components a
