29、ual to or less than 3,7 at 1 GHz) and flammability (vertical burning test), copper-clad 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
30、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 International Standards, Technical Specifications, Technical Reports, Publicly Available Specifications (PAS) and
31、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 in this preparatory work. International, governmental and non-governmental organizations liaising with the I
32、EC also participate in this preparation. IEC collaborates closely 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
33、 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 have the form of recommendations for international use and are accepted by IEC National Committees in that sens
34、e. 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 misinterpretation by any end user. 4) In order to promote international uniformity, IEC National Committees unde
35、rtake 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 national or regional publication shall be clearly indicated in the latter. 5) IEC provides no marking procedure t
36、o indicate its approval and cannot be rendered responsible for any equipment declared to be in conformity with an IEC Publication. 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 inc
37、luding 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 expenses arising out of the publication, use of, or rel
38、iance 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) Attention is drawn to the possibility that some of the
39、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. International Standard IEC 61249-2-32 has been prepared by IEC technical committee 91: Electronics assembly technology. The text of this standard is
40、based on the following documents: FDIS Report on voting 91/828/FDIS 91/843/RVD Full information on the voting for the approval of this standard 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. 6124

The committee has decided that the contents of this publication will remain unchanged until the maintenance
42、 result date indicated on the IEC web site under “http:/webstore.iec.ch“ in the data related to the specific publication. At this date, the publication will be reconfirmed, withdrawn, replaced by a revised edition, or amended. 6 61249-2-32 IEC:2009 MATERIALS FOR PRINTED BOARDS AND OTHER INTERCONNECT
43、ING STRUCTURES Part 2-32: Reinforced base materials, clad and unclad Halogenated modified or unmodified resin system, woven E-glass laminate sheets of defined relative permittivity (equal to or less than 3,7 at 1 GHz) and flammability (vertical burning test), copper-clad 1 Scope This part of IEC 612
44、49 specifies requirements for properties of modified epoxide woven E-glass laminate sheet of a thickness of 0,05 mm up to 3,2 mm, of defined flammability (vertical burning test), copper-clad. The glass transition temperature is defined to be 150 C minimum. The relative permittivity is equal to or le
45、ss than 3,7 and the dissipation factor is equal to or less than 0,007 0 at 1 GHz. Some property requirements may have several classes of performance. The class desired should be specified in the purchase order; otherwise the default class of material will be supplied. 2 Normative references The foll
