Device embedded substrate - Generic specification - Test method
This part of IEC 62878 specifies the test methods of passive and active device embedded
substrates. The basic test methods of printed wiring substrate materials and substrates
themselves are specified in IEC 61189-3.
This part of IEC 62878 is applicable to device embedded substrates fabricated by use of
organic base material, which include for example active or passive devices, discrete
components formed in the fabrication process of electronic wiring board, and sheet formed
components.
The IEC 62878 series neither applies to the re-distribution layer (RDL) nor to the electronic
modules defined as an M-type business model in IEC 62421.

L'IEC 62878-1-1:2015 spécifie les méthodes d'essai pour les substrats avec appareils actifs et passifs intégrés. Les méthodes d'essai fondamentales pour les matériaux de substrats de câblage imprimé et pour les substrats eux-mêmes sont spécifiées dans l'IEC 61189-3. La présente partie de l'IEC 62878 est applicable aux substrats avec appareil(s) intégré(s) fabriqués à partir de matériaux de base organiques, y compris par exemple les appareils actifs ou passifs, les composants discrets formés lors du processus de fabrication d'une carte de câblage électronique, ainsi que les composants de feuilles minces.

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 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 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 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 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 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 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 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 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 bodies. 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 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 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 all such patent rights. International Standard IEC 62878-1-1 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 91/1248/FDIS 91/1260/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. A list of all parts in the IEC 62878, published under the general title Device embedded substrate, can be found on the IEC website.

The test shall be carried out at the standard air conditions (or simply stated as standard environment): Temperature Relative humidity Atmospheric pressure 15°C to 35°C 25 % to 75 % 86 kPa to 106 kPa 4.2 Visual inspection and micro-sectioning 4.2.1 General Visual inspection and micro-sectioning of multi-layer printed wiring boards are specified in 4.2.2 and 4.2.3. 4.2.2 Visual inspection Visual inspection consists of checking the appearance, finish, and pattern of specimens using the naked eye or a magnifying glass in reference to its individual specification. The test result shall be as agreed between user and supplier (hereafter referred as AABUS). 4.2.3 Micro-sectioning Micro-sectioning is to check the state, appearance, and dimensions according to individual specifications of the plated through hole, the via in the build-up layer, the conductor, the interlayer distance, the conductor distance, and the connections to the embedded device. The specimen is mounted in epoxy or polyester resin and the specimen is cross-sectioned and polished for observation. The evaluation of the results shall be AABUS. The equipment, material, specimen and test are specified in a) to d). a) Equipment An industrial microscope capable of measuring plated film thicknesses with an accuracy of 0,001 mm. b) Material Materials used in this test are releasing agent, moulding resin, polishing cloth or paper (#180, #400, #1 000, etc.) with the option to use polishing materials (alumina or chromium oxide). c) Specimen A specimen is cut from the product to an appropriate size sufficient for observation and mounted in moulding resin. The cut surface is then polished with polishing cloth/paper starting from coarse to fine using a rotating felt surface and the above mentioned polishing material. The polishing face shall be within an angle of 85° to 95° to the layer to be observed. The diameter of the plated film of the through hole and of the vias in the build-up layer observed by micro-sectioning shall be no less than 90 % of the previously observed hole diameter. Etch the specimen if the boundary of the plating needs to be clarified after polishing. d) Test The test consists of observing the items specified in the individual specifications by means of a microscope of specified magnification. Figure 1 illustrates the test items for the through hole to check the micro-sectioned faces, and Figure 2 for the build-up structure and embedded devices. Table 1 gives the characteristics and observation items of the test. SIST EN 62878-1-1:2015
