United Kingdom National Specifications and Standards for Printed Circuits

BS 9760 and three sectional specifications for rigid printed circuit boards have now been published. The Institute's representative on BSI Technical Committee ECL/19 outlines the new standard system and shows that it offers a good opportunity of achieving international status. The future of BS 4025, the best known British Standard for printed circuit boards, BS 4597 and the interim Defence Standards is limited. The author appeals to Institute members to support ECL/19 in its work of ensuring that the printed circuit producer and user have meaningful and cost‐effective standards.
