Printed boards and printed board assemblies - Design and use - Part 7: Electronic component zero orientation for CAD library construction
IEC 61188-7:2017(E) establishes a consistent technique for the description of electronic component orientation, and their land pattern geometries. This facilitates and encourages a common data capture and transfer methodology amongst and between global trading partners. This edition includes the following significant technical changes with respect to the previous edition: a) Figure 1 has been corrected; b) the term “rectangle” has generally been replaced by “polygon”; c) level B has been indicated as preferred level for new libraries.

L’IEC 61188-7:2017 établit une technique cohérente pour décrire l’orientation des composants électroniques, ainsi que les géométries de leurs zones de report. Cela facilite et encourage une méthodologie commune de saisie et de transfert des données parmi et entre les partenaires commerciaux mondiaux. Cette édition inclut les modifications techniques majeures suivantes par rapport à l'édition précédente: a) la Figure 1 a été corrigée; b) le terme “ rectangle “ a été généralement remplacé par “ polygone “; c) le niveau B a été indiqué comme niveau à privilégier pour les nouvelles bibliothèques.

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 61188-7 has been prepared by IEC technical committee 91: Electronics assembly technology. This second edition cancels and replaces the first edition published in 2009. This edition constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous edition: a) Figure 1 has been corrected; b) the term “rectangle” has generally been replaced by “polygon”; c) level B has been indicated as preferred level for new libraries. SIST EN 61188-7:2017
– 4 – IEC 61188-7:2017 IEC 2017 The text of this International Standard is based on the following documents: CDV Report on voting 91/1382/CDV 91/1428/RVC
Full information on the voting for the approval of this International Standard can be found in the report on voting indicated in the above table. This document has been drafted in accordance with the ISO/IEC Directives, Part 2. A list of all parts of the IEC 61188 series, under the general title Printed boards and printed board assemblies – Design and use, can be found on the IEC website. The committee has decided that the contents of this document will remain unchanged until the stability date indicated on the IEC website under "http://webstore.iec.ch" in the data related to the specific document. At this date, the document will be
