摘要： A copper-alloy foil used for a laminate sheet achieves 5.0N/cm or more of 180° peeling strength when thermally fusion-bonded with liquid crystal polymer. The copper-alloy foil contains one or more of from 0.01 to 2.0% of Cr and from 0.01 to 1.0% of Zr. An oxide layer and occasionally a rust-proof film present on the outermost surface is 10 nm or less. The electrical conductivity is 50% IACS.

摘要： Conductors, which are formed on a suspension member of the hard-disc drive suspension, are subject to thermal expansion and shrinkage during the laminating process with a substrate via a polyimide binder. The tracking width of the suspension member is influenced by the thermal expansion and shrinkage. In order to provide a copper-alloy foil, which can attain improved tracking width, the following ratio of thermal expansion and shrinkage is adjusted in a range of from −0.1 to +0.1% &Dgr;(%)=(l−l0)/l0×100 where l0 the length of a specimen before heating at 330° C. for 2 hours, and l is the length of a specimen after heating at 330° C. for 2 hours. &Dgr;(%) is measured in the direction parallel to the rolling direction.
