30、NATIONAL ELECTROTECHNICAL COMMISSION _ ELECTRONIC COMPONENTS LONG-TERM STORAGE OF ELECTRONIC SEMICONDUCTOR DEVICES Part 1: General FOREWORD 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising all national electrotechnical committees (IEC
31、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, P
32、ublicly 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- go
33、vernmental 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 IE
34、C 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 acce
35、pted 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 internatio
36、nal 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 la
37、tter. 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 sho
38、uld 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 dam
39、age 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
40、 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 righ
41、ts. International Standard IEC 62435-1 has been prepared by IEC technical committee 47: Semiconductor devices. This standard cancels and replaces IEC/PAS 62435 published in 2005. This first edition constitutes a technical revision. The text of this standard is based on the following documents: FDIS
42、Report on voting 47/2326/FDIS 47/2349/RVD Full information on the voting for the approval of this standard can be found in the report on voting indicated in the above table. IEC 62435-1:2017 IEC 2017 5 This publication has been drafted in accordance with the ISO/IEC Directives, Part 2. A list of all
43、 parts in the IEC 62435 series, published under the general title Electronic components Long-term storage of electronic semiconductor devices, can be found on the IEC website. The committee has decided that the contents of this publication will remain unchanged until the stability date indicated on
44、the IEC website under “http:/webstore.iec.ch“ in the data related to the specific publication. At this date, the publication will be reconfirmed, withdrawn, replaced by a revised edition, or amended. 6 IEC 62435-1:2017 IEC 2017 INTRODUCTION This document applies to the long-term storage of electroni
45、c components. This is a document for 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 durati
46、on storage. 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. Although it has always existed to some extent, obsolescence of electronic components
47、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,
48、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
49、or production, for example: remedial storage as soon as components are no longer marketed; preventive storage anticipating declaration of obsolescence. Taking into account the expected life of some installations, sometimes covering several decades, the qualification times, and the unavailability costs, which can also be very high, the solution to be adopted to resolve obsolescence should often be rapidly
