28、TERCONNECTING STRUCTURES Part 2-36: Reinforced base materials, clad and unclad Epoxide woven E-glass laminate sheets of defined flammability (vertical burning test), copper-clad for lead-free assembly FOREWORD 1) The International Electrotechnical Commission (IEC) is a worldwide organization for sta
29、ndardization comprising all national electrotechnical committees (IEC National Committees). The object of IEC is 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 I
30、nternational Standards, Technical Specifications, Technical Reports, Publicly Available Specifications (PAS) and 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 partici
31、pate in this preparatory work. International, governmental and non- governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely with the International Organization for Standardization (ISO) in accordance with conditions determined by agreement betw
32、een 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 relevant subjects since each technical committee has representation from all interested IEC National Committees. 3) IEC Publicatio
33、ns 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 technical content of IEC Publications is accurate, IEC cannot be held responsible for the way in which they are used or for an
34、y misinterpretation by any end user. 4) In order to promote international uniformity, IEC National Committees undertake 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
35、 national or regional publication shall be clearly indicated in the latter. 5) IEC provides no marking procedure to 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 ed
36、ition of this publication. 7) No liability shall attach to IEC or 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 d
37、irect or indirect, or for costs (including legal fees) and expenses 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 indispe
38、nsable for the correct application of this publication. 9) Attention 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. International Standard IEC 61249-2-
39、36 has been prepared by IEC technical committee 91: Electronics assembly technology. The text of this standard is based on the following documents: FDIS Report on voting 91/801/FDIS 91/824/RVD Full information on the voting for the approval of this standard can be found in the report on voting indic
40、ated in the above table. This publication has been drafted in accordance with the ISO/IEC Directives, Part 2. 61249-2-36 IEC:2008 5 A list of all parts of the IEC 61249 series, under the general title Materials for printed boards and other interconnecting structures, can be found on the IEC website.
41、 The committee has decided that the contents of this publication will remain unchanged until the maintenance 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
42、 by a revised edition, or amended. 6 61249-2-36 IEC:2008 MATERIALS FOR PRINTED BOARDS AND OTHER INTERCONNECTING STRUCTURES Part 2-36: Reinforced base materials, clad and unclad Epoxide woven E-glass laminate sheets of defined flammability (vertical burning test), copper-clad for lead-free assembly 1
43、 Scope This part of IEC 61249 gives requirements for properties of di-functional brominated epoxide woven E-glass laminate sheet 0,05 mm up to 3,2 mm, of defined flammability (vertical burning test), copper-clad. The glass transition temperature is defined to be 120 C minimum. Its flame resistance i
44、s defined in terms of the flammability requirements of 7.3. Some property requirements may have several classes of performance. The class desired should be specified on the purchase order otherwise the default class of material will be supplied. 2 Normative references The following referenced docume
45、nts are indispensable for the application of this document. For dated references, only the edition cited applies.
