Filed: 1988-12-24
Abstract: PURPOSE:To provide a copper alloy for lead frame applicable to all semiconductor products by specifying the surface hardness and the center line average height and maximum height of surface roughness of a copper alloy containing specific amounts of Ni and Sn, respectively. CONSTITUTION:This copper alloy is prepared by regulating the surface of an alloy material having a composition consisting of, by weight, 0.5-10.0% Ni, 0.3-3.0% Sn, and the balance Cu so that surface hardness is >=150 and surface roughness is <=0.15mu by center line average height Ra and <=0.8mu by maximum height Rmax. In the above alloy, high strength and high electric conductivity cannot be obtained when Ni content is below the lower limit, and, when it exceeds the upper limit, workability, direct bonding property, and solderability are deteriorated. As to Sn content, high strength and high electric conductivity cannot be obtained when it is below the lower limit, and, when it exceeds the upper limit, workability and electric conductivity are deteriorated. Further, when the values of the above Hv, Ra, and Rmax are <150, >0.15mu, and >0.8mu, respectively, the adhesive strength of bonding wire is deteriorated and, as a result, there are cases where peeling is brought about in a resin sealing stage, etc.
