12、eword 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 CENELEC
13、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 prEN 12
14、3000 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 They will be withdrawn only if they are replaced by revised EN standards.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 the EN
15、 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) Refere
16、nces 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. This Bri
17、tish Standard is a capability detail specification, based upon the sectional specification, BS 123200. It should be read in conjunction with the generic specification, BS 123000, and the sectional specification, BS 123200. Users of printed boards procured using this capability detail specification s
18、hould 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. Many of the illustrations in this British Standard have been included courtesy of IPC. Mor
19、eover, selected requirements from ANSI/IPC A-600F have been incorporated into the requirements of this British Standard.

Users of British Standards are responsible for their correct application. Compliance with a British Standard does not of itself confer immunity
