The Metallic foil Subcommittee of the Base Material Committee (formerly the Copper Foil Subcommittee of the Raw Materials Committee) decided in August 1982 to undertake a round robin test program on copper foil ductility. The objectives of this Round Robin Study were set by the Subcommittee to be:
- the determination of typical ductility values for the various types and classes of copper foil from different foil manufacturers;
- the establishment of minimum ductility requirements for the IPC-CF-150, Copper Foil for Printed Wiring Applications
- the round robin testing of the fatigue ductility test method for metallic foils to
- determine critical and sensitive test method steps, and
- if necessary, generate the information to emphasize and elucidate any critical test method steps,
- the establishment of the extent to which the relationship underlying the fatigue ductility test method can be utilized to predict the high-cycle fatigue behavior of metallic foils, and
- the determination of the bending fatigue behavior of the copper foils
