It is identical with CENELEC Electronics Components Committee (CECC) 23200:1985 “Harmonized system of qual
9、ity assessment for electronic 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 BS CECC 23000 In 1992 the CENELEC Electronic Components Comm
10、ittee (CECC) accepted CECC 23200:1985 as European Standard EN 123200:1992. There is no British Standard equivalent to CECC 00010 which comprises only a list of the tests in IEC 326-2 and its supplement IEC 326-2A. The Technical Committee has reviewed the provisions of IEC 194, IEC 321 and IEC 326-3,
11、 to which reference is made in the text, 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
12、 with a British Standard does not of itself confer immunity from legal obligations.

23、ries 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 specifications and quality assessment pr
24、ocedures 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 been formally approved by the CECC, and has
25、 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 the CECC System. Preface This Sectional
26、Specification was prepared by CECC Working Group 23: 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 was ratified by the President of the CE
27、CC 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.

The fol
35、lowing document comprises this IEC-Standard and in accordance with the generic specification CECC 23000 the information additionally necessary for printed boards intended to be handled within the CENELEC system for Electronic Components of Assessed Quality. 1.1 Scope and object This document is a Se
36、ctional 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 and the test methods to be used for capability approv
37、al testing and for quality conformance inspection (lot-by-lot and periodic inspection). 1.2 Related documents IEC 68, Basic environmental testing procedures. IEC 194, Terms and definitions for printed circuits. IEC 249, Metal-clad base materials for printed circuits. IEC 321, Guidance for the design
38、 and use of components intended for mounting on printed boards. IEC 326-2, Printed boards test methods. IEC 326-3, Design and use of printed boards.

39、eric 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 Specification (Cap DS) applying to specific materials, e.
40、g. according to IEC 249-2, 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 CECC 00111). Customer Detail Specification (CDS) for the custom
41、 built printed boards, according to 5 of CECC 23000. The CDS will normally be written by the customer and allocated a number within his own system. Further details are also given in CECC 23000 and in CECC 00107-III. Table I contains the basic characteristics that will normally be important for singl
42、e 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 boards with plated-through holes and/or certain
43、 applications and makes reference to the appropriate tests to verify these characteristics. Where necessary, the relevant specification may quote characteristics and tests from this Table II. Where additional details for a test have to be specified in the relevant specification, this is indicated by
44、 an asterisk in the relevant column. These details shall then be specified in accordance with CECC 00010 (IEC 326-2). Table III contains the capability test programme. A specified composite test pattern (CTP) is used as capability qualifying component. Table IV contains the information for the quali
45、ty conformance inspection. The tables are not intended to prescribe a test sequence, the tests may be carried out in any sequence, unless otherwise specified.

46、t specimens 3.1 Capability Approval 3.1.1 Basic Capability The test shall be carried out on the composite test pattern given in 8. 3.1.2 Additional Capability 3.5.3 of CECC 23000 shall apply. For multiple arrangements see also 8. 3.1.3 Maintenance of Capability Approval 3.8 of CECC 23000 shall apply
47、. 3.2 Quality conformance inspection Unless otherwise specified production 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 ma
48、y be based on the appropriate pattern of the composite test pattern clause 8. 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
49、 applied to a specific material and technique, as applicable. The relevant specification shall contain all information necessary to define the printed board clearly and completely. The recommendations given in IEC 326-3 shall preferably be followed. Care should be taken to avoid unnecessary prescriptions. Permissible deviations shall be stated where necessary, nominal values 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,
