2、 the JEDEC Board of Directors level and subsequently reviewed and approved by the JEDEC legal counsel. JEDEC standards and publications are designed to serve the public interest through eliminating misunderstandings between manufacturers and purchasers, facilitating interchangeability and improvemen

3、t of products, and assisting the purchaser in selecting and obtaining with minimum delay the proper product for use by those other than JEDEC members, whether the standard is to be used either domestically or internationally. JEDEC standards and publications are adopted without regard to whether or

4、not their adoption may involve patents or articles, materials, or processes. By such action JEDEC does not assume any liability to any patent owner, nor does it assume any obligation whatever to parties adopting the JEDEC standards or publications. The information included in JEDEC standards and pub

5、lications represents a sound approach to product specification and application, principally from the solid state device manufacturer viewpoint. Within the JEDEC organization there are procedures whereby a JEDEC standard or publication may be further processed and ultimately become an ANSI standard.

JEDEC Standard No. 22-B103B.01 -i- Test Method B103B.01 (Revision of B103-B) VIBRATION, VARIABLE FREQUENCY Foreword The variable fre

10、quency vibration test is performed to determine the effect of vibration, within a specified frequency range, on the internal structural elements. JEDEC Standard No. 22-B103B.01 Test Method B103B.01 -ii- (Revision of B103-B) JEDEC Standard No. 22-B103B.01 Page 1 Test Method B103B.01 (Revision of B103

11、-B) VIBRATION, VARIABLE FREQUENCY (From JEDEC Board Ballot, JCB-02-32, and JCB-16-33, formulated under the cognizance of the JC-14.1 Subcommittee on Reliability Test Methods for Packaged Devices.) 1 Scope This method is intended to evaluate component(s) for use in electrical equipment. It is intende

12、d to determine the ability of the component(s) to withstand moderate to severe vibration as a result of motion produced by transportation or field operation. Vibration of this type may disturb operating characteristics, particularly if the repetitive stress causes fatigue. This is a destructive test

13、 intended for component qualification. It is normally applicable to cavity-type packages. 2 Apparatus Apparatus for this test shall include equipment capable of providing the required variable frequency vibration at the specified levels and the necessary optical and electrical equipment for post-tes

14、t measurements. 3 Terms and definitions 3.1 RMS acceleration The root mean square average of the acceleration interval of the dynamic motion. 3.2 Peak acceleration The maximum of the acceleration interval of the dynamic motion. 3.3 Logarithmic sweep Continuously varying the frequency in a manner suc

15、h that within any portion of the frequency range, a fixed number of decades is traversed in a fixed length of time. 3.4 Octave A measurement of the spacing of frequency characterized by a doubling of frequency. The number of octaves, N, between two frequencies, f1f2, is given by N=(log f2/f1 ) / log

16、 2. 3.5 Decade A measurement of the spacing of frequency characterized by a tenfold increase of frequency. The number of decades, D, between two frequencies, f1f2, is given by D= (log f2/f1) / log 10. JEDEC Standard No. 22-B103B.01 Page 2 Test Method B103B.01 (Revision of B103-B) 3 Terms and definit

17、ions (contd) 3.6 Decibel measurement of PSD, dB A measurement of the ratio R of one level of power spectral density, s1, relative to another reference level, s2, given by the formula R = 20 log (s1 / s2) / log 10. R=6dB is approximately a doubling of power spectral density from one level to another.

18、 3.7 Power spectral density, PSD A measurement of the intensity of acceleration power per unit frequency, in units of G squared per Hz. 3.8 Service condition The designation of the severity of test used to evaluate a component. 3.9 Velocity change The integral of the acceleration interval of the dyn

19、amic motion over the interval. 3.10 Cavity package A component that has the device located within the cavity of the package body. 3.11 Peak-peak displacement The maximum difference between highest and lowest values of the displacement of the dynamic motion interval. 3.12 Gaussian random vibration Vi

20、bration characterized by having acceleration and frequency values over an interval of time which occur in a stochastic manner, with the acceleration values following a normal (Gaussian) probability density function and frequency values following a uniform distribution. 4 Procedure 4.1 Component sele

21、ction Components subjected to the test will be randomly selected and typical of production. The component shall be rigidly mounted or restrained by its case with suitable protection for the leads. If component rework, burn in or other stressful process is to be considered, then such a process or pro

22、cesses should be applied to the component(s) prior to vibration test. Use of such processes in the test hardware preparation will be documented in the test results. JEDEC Standard No. 22-B103B.01 Page 3 Test Method B103B.01 (Revision of B103-B) 4.2 Required stress application - swept sine test 4.2.1

23、 Mounting the component The device case shall be rigidly fastened on the vibration platform and the leads adequately secured to avoid excessive lead resonance. The components will be mounted in such a manner so that they experience the full-specified vibration level at the component. 4.2.2 Vibration

24、 application Vibration will be applied to the components outer surface casing or leads in a manner to simulate expected vibration during non-shipment conditions. The devices shall be vibrated with simple harmonic motion corresponding to the test levels shown in Table 1. At least one service conditio

25、n must be designated. Each test level will include simple harmonic motion of continuously swept frequency with the indicated peak-peak displacement below the crossover frequency, and indicated peak acceleration above the crossover frequency. A tolerance level of +/- 10% on the test being performed,

26、either displacement or acceleration, is allowed. The test frequency range is from the indicated minimum frequency to the indicated maximum test frequency. A complete sweep of the test frequency range, from the minimum to maximum and return to the minimum frequency, shall be traversed in a logarithmi

27、c manner, in 4 minutes. The sweep rate is 1 decade/minute. This complete sweep shall be performed 4 times in each of the orientations X, Y, and Z (total of 12 times). If there are no significant stress sensitivities of the component under test in a particular frequency range (for examples, in the lo

28、wer frequency ranges, or in a region of an uncontrollable fixture resonance), then that portion of the frequency sweep may be deleted from the stress application with full documentation of the reasons for the test exception and extent of the portion(s) of the sweep test deleted.

32、will be applied to the components outer surface casing or leads in a manner to simulate expected vibration during packaged shipment. The devices shall be vibrated with Gaussian random vibration corresponding one of the service conditions with associated overall test level as shown in Table 2. Detail

33、s of the power spectral density PSD functions for these test levels are given in Table 3, Table 4, Table 5, and Table 6 as breakpoints of the curves. Table 3, Table 4, Table 5, and Table 6 are plotted out in the curves found in Figure 1. In general, Component test levels A, B and C represent shippin

34、g conditions for the component, with condition A being the most extreme. Test conditions D - I represent various levels of application vibrations to which a component can be exposed. Condition D is the most severe. Selection of the appropriate test condition should be based on the actual shipping or

35、 application condition requirement for the component. The vibration will be applied for 30 minutes in each of 3 orthogonal axes, for every service condition. At least one service condition must be designated, and subjected to the required test level for a minimum of 90 minutes in total, to complete

36、all three axes.
