11、400-003:2001 ii BSI 17 December 2001 Foreword This British Standard has been prepared by Technical Committee EPL/501, Electronic assembly technology. The BS 123000:2001 series of British Standards is based on draft proposals to revise the EN 123000 series dated 1992 and 1997. These were circulated a
12、nd voted on in CENELEC, but the CENELEC Technical Board decided not to approve them for publication. Following repeated attempts by the British National Committee to get them published, the Technical Board agreed to grant derogation from standstill to the British National Committee to publish nation
13、al standards on the basis of the prEN 123000 series (Technical Board decision D106/092). These standards are published to complement the BS EN 123000 series, which remains current. They will be withdrawn only if they are replaced by revised EN standards. They have been published because they are con
14、sidered to be an improvement upon the EN series, for the following reasons. a) Requirements for modern materials and surface finishes required by the electronics industry have been incorporated. b) Reference is made to ANSI/IPC A-600F for many of the inspection criteria. This has been undertaken in
15、response to industry requests. c) References to obsolete CECC regulatory documents have been replaced. d) Tests and requirements that are no longer considered relevant have been removed. e) The UK electronics industry requires standards that are subject to ongoing revision, in order to take account
16、of new European Eco-Directives. This British Standard is a capability detail specification, based upon the sectional specification, BS 123400. It should be read in conjunction with the generic specification, BS 123000, and the sectional specification, BS 123400. Users of printed boards procured usin
17、g this capability detail specification should satisfy themselves that the sample sizes and frequencies are appropriate for the needs of their product. Alternative requirements should be included in the customer detail specification. ACKNOWLEDGEMENT. Selected requirements from ANSI/IPC A-600F have be
18、en incorporated into the requirements of this British Standard.

19、iii Annex A, Annex B, Annex C, Annex D and Annex E are normative. It has been assumed in the preparation of this British Standard that the execution of its provisions will be entrusted to appropriately qualified and experienced people, for whose use it has been produced. A British Standard does not
20、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 itself confer immunity from legal obligations. Summary of pages This document comprises a front cover, an inside fro

22、to be tested, the test methods and conditions to be applied and the requirements to be fulfilled for testing basic and additional capability, in relation to flexible single-sided and double-sided printed boards without through-connections. It is applicable for flexible single-sided and double-sided
23、printed boards without through-connections made with the materials and surface finishes specified in clause 4. This British Standard is a capability detail specification intended for use with the IECQ system of quality assessment for electronic components. 2 Normative references The following normat
24、ive documents contain provisions which, through reference in this text, constitute provisions of this British Standard.
