8、nts A1:1995 and A2:1996, published by the European Committee for Electrotechnical Standardization (CENELEC). This standard is a harmonized specification within the CECC system. In1991 theCENELEC Electronic Components Committee (CECC) accepted CECC23000:1985 as European Standard EN123000:1991. The re
9、lated BS9760:1977 specification is now declared obsolescent. Cross-references. The British Standard which implements CECC00100 is BS9000 “General requirements for a system for electronic components of assessed quality” Part2 “Specification for national implementation of CECC basic rules and rules of
10、 procedure”. CECC 00107-I and CECC00107-III have been replaced by EN10114-1:1994 and CECC00114-3:1994 respectively, and are also implemented by BS9000-2:1996. There is no British Standard equivalent to CECC00010:1980 which comprises only a list of the tests in IEC326-2:1976 and its supplement IEC326
11、-2A. The Technical Committee has reviewed the provision of IEC194:1988, IEC410:1973 and CECC00007:1978, 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 Standard to IEC410:1973 and CECC00007:1978 is BS6001“Sa

A British Standard does not purport to include all the necessary provisions of a contract. Users of British Standards are responsible for
13、their correct application. Compliance with a British Standard does not of itself confer immunity from legal obligations.

22、assessed quality. 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
23、 the System are 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 b
24、e read in conjunction 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 UnitedK
25、ingdom, and copies of it can be obtained from the addresses shown on the blue fly sheet. Preface This generic specification was prepared by CECC Working Group23: Printed Circuits. It is based on the publications of the International Electrotechnical Commission (IEC). The text of this specification w
26、as circulated 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 F
27、ULL EDITORIAL PROCEDURE BEING APPLIED. USERS OF THE SPECIFICATION ARE ASKED TO REPORT TO THE CECC GENERAL SECRETARIAT ANY ERRORS THEY FIND SO THAT AMENDING ACTION CAN BE INITIATED. The text is published initially in English and German. The French version will follow as soon as it has been prepared.

General 1.1 Scope This 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
43、 irrespective of their method of manufacture, when they are ready for mounting of the components. 1.2 Object To define system and procedure for approval of manufacturers and products and to provide rules for the preparation of specifications for printed boards. 1.3 Related documents IEC 194, Terms a
44、nd definitions for printed boards. IEC 249, Metal-clad base materials for printed boards. IEC 326-2, Printed circuits Test methods. IEC 410, Sampling plans and procedures for inspection by attributes. CECC 00007, Sampling plans and procedures for inspection by attributes. CECC 00010, Printed board T
45、est methods. 1.4 General considerations Printed boards differ from most other electronic components in important factors, such 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 detai
46、ls for a particular board must be agreed between customer and manufacturer, although they are made in considerable total quantities, the production quantity of a particular printed board may be small. Therefore, the CECC Qualification Approval Procedure as detailed in CECC00107-1 cannot be applied.
47、Instead of this, it is necessary to use the CECC Capability Approval Procedure as laid down in CECC00107-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 requirement
48、s for each type of printed board, e.g. single/double sided, with plain holes single/double sided, with plated-through holes multilayer printed boards flexible printed boards. NOTEThis list is not intended to be exhaustive. An important requirement of capability approval is that a manufacturer shall
49、demonstrate the claimed capability of his facilities and processes. In the case of printed boards “basic” and “additional” capability are distinguished (see also3.1, 3.5.2, and3.5.3 of this GS). Basic capability is the capability defined in a CECC or ONH.Cap DS. The term “basic” is not intended to indicate any minimum level of assessment, testing or requirement. Additional capability is any capability in addition to the basic capability. Examples of additional capability: maximum size of printed boards that can be processed minimu
