Electronic components - Long-term storage of electronic semiconductor devices - Part 9: Special cases
IEC 62435-9:2021 specifies storage practices encompassing silicon and semiconductor device building blocks of all types that are integrated together to into products in the form of either packages or boards that can be stored as fully assembled units or partial assemblies. Special attention is given to memories as components and assemblies although methods also apply to heterogeneous components. Guidelines and requirements for customer-supplier interaction are provided to manage the complexity. NOTE In IEC 62435 (all parts), the term "components" is used interchangeably with dice, wafers, passives and packaged devices.
Elektronische Bauteile - Langzeitlagerung elektronischer Halbleiterbauteile – Teil 9: Sonderfälle
Composants électroniques - Stockage de longue durée des dispositifs électroniques à semiconducteurs - Partie 9: Cas particuliers
L’IEC 62435-9:2021 spécifie les pratiques de stockage de tous les types de blocs modules au silicium et à semiconducteurs, intégrés dans des produits sous la forme de boîtiers ou de cartes qui peuvent être stockés en unités intégralement assemblées ou en ensembles partiels. Les mémoires, qu’il s’agisse de composants ou d’ensembles, font l’objet d’une attention particulière, même si les méthodes s’appliquent également aux composants hétérogènes. Des lignes directrices et des exigences en matière d’interaction client/fournisseur sont données afin de gérer la complexité. 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.
IEC 62435-9 has been prepared by IEC technical committee 47: Semiconductor devices. It is
