9、on: Printed boards, including amendments A1:1995 and A2:1996, published by the European Committee for Electrotechnical Standardization (CENELEC). This standard is a harmonized specification within the CECC system. In 1991 the CENELEC Electronic Components Committee (CECC) accepted CECC 23000:1985 as
10、 European Standard EN 123000:1991. The related BS 9760:1977 specification is now declared obsolescent. Cross-references. The British Standard which implements CECC 00100 is BS 9000 “General requirements for a system for electronic components of assessed quality” Part 2 “Specification for national im
11、plementation of CECC basic rules and rules of procedure”. CECC 00107-I and CECC 00107-III have been replaced by EN 10114-1:1994 and CECC 00114-3:1994 respectively, and are also implemented by BS 9000-2:1996. There is no British Standard equivalent to CECC 00010:1980 which comprises only a list of th
12、e tests in IEC 326-2:1976 and its supplement IEC 326-2A. The Technical Committee has reviewed the provision of IEC 194:1988, IEC 410:1973 and CECC 00007:1978, to which reference is made in the text, and has decided that they are acceptable for use in conjuction with this standard. A related British
13、Standard to IEC 410:1973 and CECC 00007:1978 is BS 6001 “Sampling procedures for inspection by attributes” Part 1:1972 “Specification for sampling plans indexed by acceptable quality level (AQL) for lot by lot inspection”. A British Standard does not purport to include all the necessary provisions o
14、f a contract. Users of British Standards are responsible for their correct application. Compliance with a British Standard does not of itself confer immunity from legal obligations.

23、y, (c) BSI EN 123000:1991 BSI 04-2000 2 Foreword The CENELEC Electronic Components Committee (CECC) is composed of those member countries of the European Committee for Electrotechnical Standardization (CENELEC) who wish to take part in a harmonized System for electronic components of assessed qualit
24、y. The object of the System is to facilitate international trade by the harmonization of the specifications and quality assessment procedures for electronic components, and by the grant of an internationally recognized Mark, or Certificate, of Conformity. The components produced under the System are
25、 thereby accepted by all member countries without further testing. The specification has been formally approved by the CECC, and has been prepared for those countries taking part in the System who wish to issue national harmonized GENERIC SPECIFICATIONS for PRINTED BOARDS. It should be read in conju
26、nction with the current regulations for the CECC System. At the date of printing of this specification the member countries of the CECC are Austria, Belgium, Denmark, Finland, France, Germany, Ireland, Italy, the Netherlands, Norway, Portugal, Spain, Sweden, Switzerland and the United Kingdom, and c
27、opies of it can be obtained from the addresses shown on the blue fly sheet. Preface This generic specification was prepared by CECC Working Group 23: Printed Circuits. It is based on the publications of the International Electrotechnical Commission (IEC). The text of this specification was circulate
28、d to the CECC for voting in the documents indicated below and was ratified by the President of the CECC for printing as a CECC Specification. SECRETARIAT NOTE: DUE TO THE URGENT INDUSTRIAL NEED FOR THIS SPECIFICATION, THE PRESIDENT OF THE CECC HAS RULED THAT IT BE PUBLISHED WITHOUT THE FULL EDITORIA

45、his document is a Generic Specification (GS) applying to printed boards within the CENELEC system for Electronic Components of Assessed Quality. It relates to printed boards irrespective of their method of manufacture, when they are ready for mounting of the components. 1.2 Object To define system a

48、as there are no standard boards with standard patterns and dimensions but an infinite variety of shapes and circuit configurations, they are “custom tailored”, i.e. all details for a particular board must be agreed between customer and manufacturer, although they are made in considerable total quant
49、ities, the production quantity of a particular printed board may be small. Therefore, the CECC Qualification Approval Procedure as detailed in CECC 00107-1 cannot be applied. Instead of this, it is necessary to use the CECC Capability Approval Procedure as laid down in CECC 00107-III. In case of printed boards capability approval is based on the use of composite test patterns as capability qualifying components with an appropriate selection of test methods and requirements for each type of printed board, e.g. single/double sided, with plain ho
