21、TS 62878-2-1:2015 IEC 2015 INTERNATIONAL ELECTROTECHNICAL COMMISSION _ DEVICE EMBEDDED SUBSTRATE Part 2-1: Guidelines General description of technology FOREWORD 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising all national electrotechn

22、ical 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 International Standards, Technical Specifications,

23、 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 participate in this preparatory work. International, gov

24、ernmental 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 between the two organizations. 2) The formal decisions

25、 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 Publications have the form of recommendations for internatio

26、nal 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 any misinterpretation by any end user. 4) In order t

27、o 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 national or regional publication shall be clearly

28、 indicated in the latter. 5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide 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 bodi

29、es. 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 including individual experts and members of its technical committees and IEC National Committees for any personal injury, property

30、 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 reliance upon, this IEC Publication or any other IEC Publications. 8) Attention is drawn to the Normative references cited in this

31、 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 elements of this IEC Publication may be the subject of patent rights. IEC shall not be held responsible for identifying any or

32、all such patent rights. The main task of IEC technical committees is to prepare International Standards. In exceptional circumstances, a technical committee may propose the publication of a Technical Specification when the required support cannot be obtained for the publication of an International S

33、tandard, despite repeated efforts, or the subject is still under technical development or where, for any other reason, there 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 de

34、cide whether they can be transformed into International Standards. IEC TS 62878-2-1, which is a Technical Specification, has been prepared by IEC technical committee 91: Electronics assembly technology. PD IEC/TS 62878-2-1:2015 5 IEC TS 62878-2-1:2015 IEC 2015 The text of this Technical Specificatio

35、n is based on the following documents: Enquiry draft Report on voting 91/1142/DTS 91/1163A/RVC Full information on the voting for the approval of this Technical Specification can be found in the report on voting indicated in the above table. A list of all parts in the IEC 62878 series, published und

The committee has decided that the contents of this publication will remain unchanged until the stability date indicated on the IEC we

PD IEC/TS 62878-2-1:2015 6 IEC TS 62878-2-1:2015 IEC 2015 INTRODUCTION This part of IEC 62878 provides guidance with respect to device embedded substrate, f

39、abricated by embedding discrete active and passive electronic devices into one or multiple inner layers of a substrate with electric connections by means of vias, conductor plating, conductive paste, and printing. Within the IEC 62878 series, IEC 62878-1-1 specifies the test methods, IEC TS 62878-2-

40、1 gives a general description of the technology, IEC TS 62878-2-3 provides guidance on design, and IEC TS 62878-2-4 specifies the test element groups. The device embedded substrate may be used as a substrate to mount SMDs to form electronic circuits, as conductor and insulator layers may be formed a

The purpose of the IEC 62878 series is to achieve a common understanding with respect to structures, test methods, design and fabrication processes and the use of the device embedded substrate in industry.
