17、mmunity Surface scan method FOREWORD 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising all national electrotechnical committees (IEC National Committees). The object of IEC is to promote international co-operation on all questions conce

18、rning standardization in the electrical and electronic fields. To this end and in addition to other activities, IEC publishes International Standards, Technical Specifications, Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC Publication(s)”). Thei

19、r preparation is entrusted to technical committees; any IEC National Committee interested in the subject dealt with may participate in this preparatory work. International, governmental and non- governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates c

20、losely with the International Organization for Standardization (ISO) in accordance with conditions determined by agreement between the 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 rel

21、evant subjects since each technical committee has representation from all interested IEC National Committees. 3) IEC Publications have 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

22、 technical content of IEC Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any misinterpretation by any end user. 4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications transparently to the maximu

23、m extent possible in their national and regional publications. Any divergence between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in the latter. 5) IEC itself does not provide any attestation of conformity. Independent certification bodies pr

24、ovide conformity assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any services 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 o

25、r its directors, employees, servants or agents including individual experts and members of its technical committees and IEC National 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 expen

26、ses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC Publications. 8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is indispensable for the correct application of this publication. 9) Atten

27、tion is drawn to the possibility that some of the elements of this IEC Publication may be the subject of patent rights. IEC shall not be held responsible for identifying any or all such patent rights. The main task of IEC technical committees is to prepare International Standards. In exceptional cir

28、cumstances, a technical committee may propose the publication of a technical specification when the required support cannot be obtained for the publication of an International Standard, despite repeated efforts, or the subject is still under technical development or where, for any other reason, ther

29、e is the future but no immediate possibility of an agreement on an International Standard. Technical specifications are subject to review within three years of publication to decide whether they can be transformed into International Standards. IEC TS 62132-9, which is a technical specification, has

30、been prepared by subcommittee 47A: Integrated circuits, of IEC technical committee 47: Semiconductor devices. PD IEC/TS 62132-9:2014IEC TS 62132-9:2014 IEC 2014 5 The text of this technical specification is based on the following documents: Enquiry draft Report on voting 47A/924/DTS 47A/936/RVC Full

31、 information on the voting for the approval of this technical specification can be found in the report on voting indicated in the above table. This publication has been drafted in accordance with the ISO/IEC Directives, Part 2. A list of all parts in the IEC 62132 series, published under the general

32、 title Integrated circuits Measurement of electromagnetic immunity, can be found on the IEC website. The committee has decided that the contents of this publication will remain unchanged until the stability date indicated on the IEC web site under “http:/webstore.iec.ch“ in the data related to the s

33、pecific publication. At this date, the publication will be transformed into an International standard, reconfirmed, withdrawn, replaced by a revised edition, or amended. IMPORTANT The colour inside logo on the cover page of this publication indicates that it contains colours which are considered to

34、be useful for the correct understanding of its contents. Users should therefore print this document using a colour printer. PD IEC/TS 62132-9:2014 6 IEC TS 62132-9:2014 IEC 2014 INTRODUCTION Techniques for generating near-fields over integrated circuits and their surrounding environment can identify

35、 the areas susceptible to radiation, which could cause errors in the device. The ability to associate magnetic or electric field strengths with a particular location on a device can provide valuable information for improvement of an IC both in terms of functionality and EMC performance. Near-field s

36、can techniques have considerably evolved over recent years. The improved efficiency, bandwidth and spatial resolution of the probes offer analysis of integrated circuits operating into the gigahertz range. Post-processing can considerably enhance the resolution of a near-field scan test bench and th

37、e measured data can be shown in various ways per users choice. PD IEC/TS 62132-9:2014IEC TS 62132-9:2014 IEC 2014 7 INTEGRATED CIRCUITS MEASUREMENT OF ELECTROMAGNETIC IMMUNITY Part 9: Measurement of radiated immunity Surface scan method 1 Scope This part of IEC 62132 provides a test procedure, which

38、 defines a method for evaluating the effect of near electric, magnetic or electromagnetic field components on an integrated circuit (IC). This diagnostic procedure is intended for IC architectural analysis such as floor planning and power distribution optimization. This test procedure is applicable

39、to testing an IC mounted on any circuit board that is accessible to the scanning probe. In some cases it is useful to scan not only the IC but also its environment. For comparison of surface scan immunity between different ICs, the standardized test board defined in IEC 62132-1 should be used. This

40、measurement method provides a mapping of the sensitivity (immunity) to electric- or magnetic-near-field disturbance over the IC. The resolution of the test is determined by the capability of the test probe and the precision of the Probe-positioning system. This method is intended for use up to 6 GHz

41、. Extending the upper limit of frequency is possible with existing probe technology but is beyond the scope of this specification. The tests described in this document are carried out in the frequency domain using continuous wave (CW), amplitude modulated (AM) or pulse modulated (PM) signals. 2 Norm

It enables the comparisons between different architectures to facilitate improvements in RF immunity of the IC. Default criteria are defined to determine the immunity level at

49、a specific location. Characterizing an IC involves the acquisition of a series of measurements of applied power to the probe at specific frequencies. Each scan over a die or package collects a large amount of data depending on the number of locations scanned and the number of frequencies measured at each location. Because of the required precision and the amount of measured data, this test method uses a computer-con
