CENELEC members are bound to comply with the CEN/CENELEC Internal Regulations which stipulate the conditions for giving this European Standard the status of a national standard without any alteration. Up-to-d

15、 and was approved by CENELEC as EN 60749-10 on 2002-07-02. This mechanical and climatic test method, as it relates to mechanical shock, is a complete rewrite of the test contained in clause 4, chapter 2 of EN 60749:1999. The following dates were fixed: latest date by which the EN has to be implement

16、ed at national level by publication of an identical national standard or by endorsement (dop) 2003-04-01 latest date by which the national standards conflicting with the EN have to be withdrawn (dow) 2005-07-01 Annexes designated “normative“ are part of the body of the standard.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, an

17、nex ZA is normative. Annex ZA has been added by CENELEC. _ Endorsement notice The text of the International Standard IEC 60749-10:2002 was approved by CENELEC as a European Standard without any modification. _ Page2 EN6074910:2002SEMICONDUCTOR DEVICES MECHANICAL AND CLIMATIC TEST METHODS Part 10: Me

18、chanical shock 1 Scope This part of IEC 60749 describes a shock test intended to determine the suitability of component parts for use in electronic equipment which may be subjected to moderately severe shocks as a result of suddenly applied forces or abrupt changes in motion produced by rough handli

19、ng, transportation, or field operation. Shock of this type may disturb operating characteristics, particularly if the shock pulses are repetitive. This is a destructive test. It is normally applicable to cavity-type packages. In general, this mechanical shock test is in conformity with IEC 60068-2-2

20、7 but, due to specific requirements of semiconductors, the clauses of this standard apply. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest editio

21、n of the referenced document (including any amendments) applies. IEC 60068-2-27:1987, Environmental testing. Part 2: Tests Test Ea and guidance: Shock 3 Test apparatus The shock testing apparatus shall be capable of providing shock pulses of 5 000 m/s 2and 15 000 m/s 2(peak) with a pulse duration be

22、tween 0,5 ms and 1,0 ms to the body of the device. The acceleration pulse as determined from the unfiltered output of a transducer with natural frequency greater than or equal to five times the frequency of the shock pulse being established shall be a half-sine waveform with an allowable distortion

23、not greater than 20 % of the specified peak acceleration. The pulse duration shall be measured between the points at 10 % of the peak acceleration during rise time and 10 % of the peak acceleration during decay time. Absolute tolerances of the pulse duration shall be 30 % of the specified duration.

24、4 Procedure The shock testing apparatus shall be mounted on a sturdy laboratory table or equivalent base and levelled before use. The device shall be rigidly mounted or restrained by its case with suitable protection for the leads. Means may be provided to prevent the shock from being repeated due t

25、o “bounce“ in the apparatus. Unless otherwise specified, the device shall be subject to five shock pulses of the peak level (g) specified in the selected test condition and for the pulse duration specified in each of the orientations X 1 , X 2 , Y 1 , Y 2 , Z 1 , and Z 2 . One required orientation (

26、Y 1 ) shall be defined as that one in which the internal element(s) tends to be removed from its mount. Unless otherwise specified, test condition B shall apply.

27、0,5 0,1 4.1 Test measurement Hermeticity tests, visual examination, and electrical measurements (consisting of parametric and functional tests) shall be performed. 4.2 Failure criteria A device shall be considered a failure if hermeticity cannot be demonstrated, if parametric limits are exceeded, or

28、 if functionality cannot be demonstrated under the conditions specified in the applicable procurement document. Mechanical damage such as cracking, chipping, or breaking of the package will also be considered as a failure, provided such damage was not caused by fixturing or handling and the damage i

29、s critical to the component performance in the specific application. 5 Summary The following details shall be specified in the applicable procurement document: a) Test condition, if other than test condition B (see Table 1). b) Electrical measurements (see 4.1). c) Sample size and accept number. d)
