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 s

22、pecifications 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 acceptable in 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 CAPABILITY DETAIL SPECIFICATIONS (Cap DS) for FLEXIBLE PRINTED BOARDS WITH THROUGH-CONNECTIONS. It should be read in conjunction with the current regulations fo

24、r 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 UnitedKingdom, and copies of it can be obtained from the a
