Silver-, nickel- and tin-coated flat conductors are currently used in a variety of electronic applications, including computer, and in the military and commercial aerospace industries. Despite this use, flat conductors made of these materials are not covered by established standards.
ASTM International Committee B01 on Electrical Conductors is now developing the following three standards to cover silver-, nickel- and tin-coated flat conductors:
WK25222, Specification for Silver-Coated Braid and Ribbon Flat Copper Wire Intended for Use in Electronic Application;
WK25223, Specification for Nickel-Coated Braid and Ribbon Flat Copper Wire Intended for Use in Electronic Application; and
WK25601, Specification for Tin-Coated Braid and Ribbon Flat Copper Wire Intended for Use in Electronic Application.
All those interested are invited to help develop the documents, under way in Subcommittee B01.04 on Conductors of Copper and Copper Alloys.
According to Stephen Childers, process engineer, IWG High Performance Conductors Inc., and a B01 member, the proposed standards will address bare conductor requirements and quality test and inspection criteria for each element. Users would be manufacturers and quality control departments within industries that use the conductors.
