9、001 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 and voted on in CENELEC, but the C
10、ENELEC 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 national standards on the basis of the
11、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 They will be withdrawn only if they are replaced by revised EN standards.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 considered to be an improvement upon
12、 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 response to industry requests. c)
13、 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 of new European Eco-Directives. T
14、his British Standard is a capability detail specification, based upon the sectional specification, BS 123800. It should be read in conjunction with the generic specification, BS 123000, and the sectional specification, BS 123800. Users of printed boards procured using this capability detail specific
15、ation 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 been incorporated into the requirem
16、ents of this British Standard.

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

20、 applied and the requirements to be fulfilled for testing basic and additional capability, in relation to flexible multilayer printed boards with through-connections. It is applicable for flexible multilayer printed boards with through-connections made with the materials and surface finishes specifi
21、ed 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 normative documents contain provisions which, through reference in this text, constitute provisions o
