8、c components: Sectional specification: Single and double sided printed boards with plated through holes”. This standard is a harmonized specification within the CECC system and should be read in conjunction with BSCECC23000 In1992the CENELEC Electronic Components Committee (CECC) accepted CECC23200:
9、1985 as European Standard EN123200:1992. There is no British Standard equivalent to CECC00010 which comprises only a list of the tests in IEC326-2 and its supplement IEC326-2A. The Technical Committee has reviewed the provisions of IEC194, IEC321 and IEC326-3, to which reference is made in the text,
10、 and has decided that they are acceptable for use in conjunction with this standard. A British Standard does not purport to include all the necessary provisions of a contract. Users of British Standards are responsible for their correct application. Compliance with a British Standard does not of its

21、 (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 quality. The object of the System is to facilitate international trade by the harmonization of the
22、 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 thereby accepted by all member countries without further testing. This specification has be
23、en formally approved by the CECC, and has been prepared for those countries taking part in the System who wish to issue national harmonized SECTIONAL SPECIFICATIONS for SINGLE AND DOUBLE SIDED PRINTED BOARDS WITH PLATED-THROUGH HOLES. It should be read in conjunction with the current regulations for
24、 the CECC System. Preface This Sectional Specification was prepared by CECC Working Group23: Printed Circuits. It is based on publications of the International Electrotechnical Commission (IEC). The text of this specification was circulated to the CECC for voting in the documents indicated below and
25、 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 EDITORIAL PROCEDURE BEING APPLIED. USERS OF THE SPECIFICATION ARE ASK
26、ED 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.

32、ided printed boards with plated-through holes. The following document comprises this IEC-Standard and in accordance with the generic specification CECC23000 the information additionally necessary for printed boards intended to be handled within the CENELEC system for Electronic Components of Assesse
33、d Quality. 1.1 Scope and object This document is a Sectional Specification (SS) relating to single and double sided printed boards with plated-through holes irrespective of their method of manufacture, when they are ready for mounting of the components. It defines the characteristics to be assessed
34、and the test methods to be used for capability approval testing and for quality conformance inspection (lot-by-lot and periodic inspection). 1.2 Related documents IEC 68, Basic environmental testing procedures.

CECC 23000, Generic Specification Printed boards of assessed quality. 2 General This Sectional Specification (SS) applies to single and double sided printed boards with plated-through holes and is intended as a basis for the preparation of Capability Detail Spec
37、ification (Cap DS) applying to specific materials, e.g.according to IEC249-2, and to be used for capability approval procedures. It may be necessary to have a Cap DS for each type of material. A Cap DS may be prepared by an international or a national body or by a manufacturer (see also CECC00111).
38、Customer Detail Specification (CDS) for the custom built printed boards, according to5 of CECC23000. The CDS will normally be written by the customer and allocated a number within his own system. Further details are also given in CECC23000 and in CECC00107-III. Table I contains the basic characteris
39、tics that will normally be important for single and double sided printed boards with plated-through holes and makes reference to the appropriate tests to verify these characteristics. Table II contains the additional characteristics that may be important for certain single and double sided printed b
40、oards with plated-through holes and/or certain applications and makes reference to the appropriate tests to verify these characteristics. Where necessary, the relevant specification may quote characteristics and tests from thisTable II. Where additional details for a test have to be specified in the
41、 relevant specification, this is indicated by an asterisk in the relevant column. These details shall then be specified in accordance with CECC00010 (IEC326-2). Table III contains the capability test programme. A specified composite test pattern (CTP) is used as capability qualifying component. Tabl
42、e IV contains the information for the quality conformance inspection. The tables are not intended to prescribe a test sequence, the tests may be carried out in any sequence, unless otherwise specified.EN123200:1992 6 BSI 01-2000 3 Test specimens 3.1 Capability Approval 3.1.1 Basic Capability The tes

44、tion boards and/or specially designed test patterns may be used for carrying out tests for the lot-by-lot and the periodic inspection. Where specially designed test patterns shall be used they may be included in the panel. They may be based on the appropriate pattern of the composite test patterncla

Consultation between manufacturer and customer will usually be necessary. 4 Relevant specification The term “Relevant Specification” means a product specification for an actual printed board, i.e.a CDS as well as a Cap DS applied to a specific material and technique, as applicable. The relevan
46、t specification shall contain all information necessary to define the printed board clearly and completely. The recommendations given in IEC326-3 shall preferably be followed. Care should be taken to avoid unnecessary prescriptions. Permissible deviations shall be stated where necessary, nominal val
47、ues without tolerances or simple maxima or minima shall be given where sufficient. Where tolerances are necessary for certain areas or parts of the printed board only, they shall be applied and restricted to those areas or parts. If there are several possibilities of presentation, of tolerance class
48、es etc., the selections given in IEC326-3 shall preferably be applied. In case of discrepancy between the CDS and any other pertinent specification (e.g.BS, GS, or SS), the CDS shall prevail. 5 Characteristics of printed boards Basic characteristics of single and double sided printed boards with pla
