34、0749-4:2017 IEC 2017 3 INTERNATIONAL ELECTROTECHNICAL COMMISSION _ SEMICONDUCTOR DEVICES MECHANICAL AND CLIMATIC TEST METHODS Part 4: Damp heat, steady state, highly accelerated stress test (HAST) FOREWORD 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standar
35、dization 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 Inter
36、national 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
37、 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 t
38、he 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 ha
39、ve 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 mis
40、interpretation 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 nati
41、onal 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
42、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
43、 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 dr
44、awn 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 no
45、t be held responsible for identifying any or all such patent rights. International Standard IEC 60749-4 has been prepared by IEC technical committee 47: Semiconductor devices. This second edition cancels and replaces the first edition published in 2002. This edition constitutes a technical revision.
46、 This edition includes the following significant technical changes with respect to the previous edition: a) clarification of requirements for temperature, relative humidity and duration detailed in Table 1; b) recommendations that current limiting resistor(s) be placed in the test set-up to prevent
47、test board or DUT damage; c) allowance of additional time-to-test delay or return-to-stress delay.
