This mechanical and clim

    15、atic test method, as it relates to storage at high temperature, is a complete rewrite of the test contained in clause 2, chapter 3 of EN 60749:1999. The following dates were fixed: latest date by which the EN has to be implemented at national level by publication of an identical national standard or

    16、 by endorsement (dop) 2003-04-01 latest date by which the national standards conflicting with the EN have to be withdrawn (dow) 2005-07-01 Annexes designated “normative“ are part of the body of the standard. In this standard, annex ZA is normative. Annex ZA has been added by CENELEC. _ Endorsement n

    17、otice The text of the International Standard IEC 60749-6:2002 was approved by CENELEC as a European Standard without any modification. _ Page2 EN607496:2002067-946 EI:C0022 3 SEMICONDUCTOR DEVICES MECHANICAL AND CLIMATIC TEST METHODS Part 6: Storage at high temperature 1 Scope The purpose of this pa

    18、rt of IEC 60749 is to test and determine the effect on all semiconductor electronic devices of storage at elevated temperature without electrical stress applied. This test is considered non-destructive but should preferably be used for device qualification. If such devices are used for delivery, the

    19、 effects of this highly accelerated stress test will need to be evaluated. In general, this test of storage at high temperature is in conformity with IEC 60068-2-48 but, due to specific requirements of semiconductors, the clauses of this standard apply. 2 Normative references The following reference

    20、d documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies. IEC 60068-2-48:1982, Environmental testing Part 2: Tests. Guidance on th

    21、e application of the tests of IEC 68 to simulate the effects of storage 3 Test apparatus The apparatus required for this test shall consist of a controlled temperature chamber capable of maintaining the specific temperature within 2 C. 4 Procedure The device under test shall be subjected to continuo

    22、us storage at 0 4 150 C for 0 72 000 1 h, except they shall be returned to room ambient conditions for interim electrical measurements. 4.1 Measurements Unless otherwise specified, interim and final electrical measurements shall be completed within 96 h after removal of the devices from the specifie

    23、d test conditions. Intermediate measurements are optional unless otherwise specified. The electrical measurements shall consist of parametric and functional tests specified in the applicable procurement document. Page3 EN607496:2002067-946 EI:C0022 4 4.2 Failure criteria A device will be considered

    24、a high temperature storage failure if parametric limits are exceeded, or if functionality cannot be demonstrated under nominal and worst-case conditions, specified in the relevant procurement document. Mechanical damage, such as cracking of the package, will be considered a failure. Cosmetic package

    25、 defects and degradation of lead finish, or solderability are not considered failure criteria. 5 Summary The following details shall be specified in the relevant specification: a) Electrical measurements (see 4.1). b) Sample size. c) Time and temperature, if other than specified (see clause 4). d) I

    26、ntermediate measurements, if required (see 4.1). _ Page4 EN607496:2002- 3 E N64709-:60022 Annex ZA (normative) Normative references to international publications with their corresponding European publications This European Standard incorporates by dated or undated reference, provisions from other pu
