1、BSI Standards Publication Qualification and performance of electrical insulating compound for printed wiring assemblies PD IEC/PAS 61249-8-1:2014National foreword This Published Document is the UK implementation of IEC/PAS 61249-8-1:2014. The UK participation in its preparation was entrusted to Tech

2、nical Committee EPL/501, Electronic assembly technology 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 collaborat

3、es 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

4、 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

5、 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 ma

6、ximum 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 bodie

7、s 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 I

8、EC 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 e

9、xpenses 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) A

10、ttention 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. A PAS is a technical specification not fulfilling the requirements for a standard, but made ava

11、ilable to the public. IEC PAS 61249-8-1, submitted by IPC has been processed by IEC technical committee 91: Electronics assembly technology. It is based on IPC-CC-830B with Amendment 1. It is published as a double-logo PAS. The structure and editorial rules used in this PAS reflect the practice of t

12、he organization which submitted it. The text of this PAS is based on the following document: This PAS was approved for publication by the P-members of the committee concerned as indicated in the following document Draft PAS Report on voting 91/1156/PAS 91/1173/RVD Following publication of this PAS,

13、the technical committee or subcommittee concerned may transform it into an International Standard. PD IEC/PAS 61249-8-1:2014IEC PAS 61249-8-1:2014 IEC 2014 3 This PAS shall remain valid for an initial maximum period of 3 years starting from the publication date. The validity may be extended for a si

14、ngle period up to a maximum of 3 years, at the end of which it shall be published as another type of normative document, or shall be withdrawn.

15、2008 Supersedes IPC-CC-830B August 2002 A standard developed by IPC Association Connecting Electronics Industries PD IEC/PAS 61249-8-1:2014The Principles of Standardization In May 1995 the IPCs Technical Activities Executive Committee (TAEC) adopted Principles of Standardization as a guiding princip

16、le of IPCs standardization efforts. Standards Should: Show relationship to Design for Manufacturability (DFM) and Design for the Environment (DFE) Minimize time to market Contain simple (simplied) language Just include spec information Focus on end product performance Include a feedback system on us

17、e and problems for future improvement Standards Should Not: Inhibit innovation Increase time-to-market Keep people out Increase cycle time Tell you how to make something Contain anything that cannot be defended with data Notice IPC Standards and Publications are designed to serve the public interest

18、 through eliminating mis- understandings between manufacturers and purchasers, facilitating interchangeability and improve- ment of products, and assisting the purchaser in selecting and obtaining with minimum delay the proper product for his particular need. Existence of such Standards and Publicat

19、ions shall not in any respect preclude any member or nonmember of IPC from manufacturing or selling products not conforming to such Standards and Publication, nor shall the existence of such Standards and Publications preclude their voluntary use by those other than IPC members, whether the standard

20、 is to be used either domestically or internationally. Recommended Standards and Publications are adopted by IPC without regard to whether their adop- tion may involve patents on articles, materials, or processes. By such action, IPC does not assume any liability to any patent owner, nor do they ass

21、ume any obligation whatever to parties adopting the Recommended Standard or Publication. Users are also wholly responsible for protecting them- selves against all claims of liabilities for patent infringement. IPC Position Statement on Specification Revision Change It is the position of IPCs Technic

22、al Activities Executive Committee that the use and implementation of IPC publications is voluntary and is part of a relationship entered into by customer and supplier. When an IPC publication is updated and a new revision is published, it is the opinion of the TAEC that the use of the new revision a

23、s part of an existing relationship is not automatic unless required by the contract. The TAEC recommends the use of the latest revision. Adopted October 6, 1998 Why is there a charge for this document? Your purchase of this document contributes to the ongoing development of new and updated indus- tr

24、y standards and publications. Standards allow manufacturers, customers, and suppliers to under- stand one another better. Standards allow manufacturers greater efficiencies when they can set up their processes to meet industry standards, allowing them to offer their customers lower costs. IPC spends

25、 hundreds of thousands of dollars annually to support IPCs volunteers in the standards and publications development process. There are many rounds of drafts sent out for review and the committees spend hundreds of hours in review and development. IPCs staff attends and par- ticipates in committee ac

26、tivities, typesets and circulates document drafts, and follows all necessary procedures to qualify for ANSI approval. IPCs membership dues have been kept low to allow as many companies as possible to participate. Therefore, the standards and publications revenue is necessary to complement dues reven

27、ue. The price schedule offers a 50% discount to IPC members. If your company buys IPC standards and publications, why not take advantage of this and the many other benets of IPC membership as well?
