28、cification set for prepreg materials, unclad (for the manufacture of multilayer boards) Multifunctional epoxide woven E-glass prepreg of defined flammability (vertical burning test) for lead-free assembly FOREWORD 1) The International Electrotechnical Commission (IEC) is a worldwide organization for
29、 standardization 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 publish
30、es International 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 par
31、ticipate 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 b
32、etween 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 Publica
33、tions 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
34、 any 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 correspond
35、ing 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
36、 edition 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, whethe
37、r direct 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 indi
38、spensable 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
39、-4-15 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 91/851/FDIS 91/863/RVD Full information on the voting for the approval of this standard can be found in the report on voting in

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 publ
42、ication will be reconfirmed, withdrawn, replaced by a revised edition, or amended. A bilingual version of this publication may be issued at a later date.

43、n set for prepreg materials, unclad (for the manufacture of multilayer boards) Multifunctional epoxide woven E-glass prepreg of defined flammability (vertical burning test) for lead-free assembly 1 Scope This part of IEC 61249 gives requirements for properties of prepreg that are mainly intended to
44、be used as bonding sheets in connection with laminates according IEC 61249-2-35 when manufacturing multilayer boards according to IEC 62326-4. Multilayer boards comprised of these materials are suitable for lead-free assembly processes. This material may also be used to bond other types of laminates
45、. Prepreg, according to this standard, is of defined flammability (vertical burning test). The flammability rating on fully cured prepreg is achieved through the use of brominated fire retardants contained as an integral part of the polymeric structure. After curing of the prepreg according to the s
46、uppliers instructions, the glass transition temperature is defined to be 150 C and 200 C. 2 Normative references The following referenced documents are indispensable for the application of this document.
