10 FOREWORD
11 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
12 all national electrotechnical committees (IEC National Committees). The object of IEC is to promote
13 international co-operation on all questions concerning standardization in the electrical and electronic fields. To
14 this end and in addition to other activities, IEC publishes International Standards, Technical Specifications,
15 Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC
16 Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested
17 in the subject dealt with may participate in this preparatory work. International, governmental and non -
18 governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely
19 with the International Organization for Standardization (ISO) in accordance with conditions determined by
20 agreement between the two organizations.
21 2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
22 consensus of opinion on the relevant subjects since each technical committee has representation from all
23 interested IEC National Committees.
24 3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
25 Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
26 Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
27 misinterpretation by any end user.
28 4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
29 transparently to the maximum extent possible in their national and regional publications. Any divergence
30 between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in
31 the latter.
32 5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity
33 assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
34 services carried out by independent certification bodies.
35 6) All users should ensure that they have the latest edition of this publication.
36 7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
37 members of its technical committees and IEC National Committees for any personal injury, property damage or
38 other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
39 expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC
40 Publications.
41 8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
42 indispensable for the correct application of this publication.
43 9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of
44 patent rights. IEC shall not be held responsible for identifying any or all such patent rights.
45 IEC 60749-5 has been prepared by IEC technical committee 47: Semiconductor devices. It is
46 an International Standard.
47 This second edition, based on JEDEC document JESD22-A118B.01, cancels and replaces the
48 first edition published in 2004. lt is used with permission of the copyright holder, JEDEC Solid
49 State Technology Association. This edition constitutes a technical revision.
50 This edition includes the following significant technical changes with respect to the previous
51 edition:
52 a) rearrangement of clauses to reposition requirements;
53 b) addition of 2 notes to the post-test electrical procedures.

47/XX/FDIS 47/XX/RVD
56 Full information on the voting for its approval can be found in the report on voting indicated in
57 the above table.
58 The language used for the development of this International Standard is English.
59 This document was drafted in accordance with ISO/IEC Directives, Part 2, and developed in
60 accordance with ISO/IEC Directives, Part 1 and ISO/IEC Directives, IEC Supplement,
61 available at www.iec.ch/members_experts/refdocs. The main document types developed by
62 IEC are described in greater detail at www.iec.ch/publications.
63 A list of all parts of the IEC 60749 series, under the general title Semiconductor devices –
64 Mechanical and climatic test methods, can be found in the IEC website.
65 The committee has decided that the contents of this document will remain unchanged until the
66 stability date indicated on the IEC website under webstore.iec.ch in the data related to the
67 specific document. At this date, the document will be
68 • reconfirmed,
69 • withdrawn,
