Aiming at the urgent need of independent guarantee of high performance strip of high-end integrated circuit lead frame, this project develops a new production process of high quality, short flow and low cost suitable for international advanced Cu-Ni-Si alloy strip, breaks through the key technology of industrial production, forms a complete set of technology with independent intellectual property rights, realizes industrial scale production and application, and replaces imports. By adopting integrated computational materials engineering (ICME) and data-driven methods, high strength and high conductivity Cu-Ni-Si alloy materials for high-end integrated circuits have been developed. The tensile strength is 922MPa, yield strength is 831MPa, and conductivity is 45%. A new production process of high quality, short flow and low cost for Cu-Ni-Si alloy strip has been developed, which breaks through the defect elimination and microstructure uniformity control problem of large-tonnage billet. The maximum weight of a single roll of casting billet reaches 8 tons. Compared with the traditional production process, the process is shortened by 38.9%, the energy consumption is reduced by 35.5%, and the yield of finished material is increased from 54.6% to 75.8%. A short process and low cost industrialization production line of "HCCM horizontal continuous casting - cold rolling - heat treatment" for Cu-Ni-Si alloy strip with an annual output of 10,000 tons has been built, realizing the industrial scale production. Cu-Ni-Si alloy strip products for high-end integrated circuits with width≥600mm and single coil weight up to 6 tons have been developed. From January to October 2022, more than 2,400 tons of strips were sold, and more than 1,450 tons of imported products were replaced (60% of the total). The cumulative sales revenue was 180 million yuan, the profit was 20 million yuan, and the economic and social benefits were remarkable. The results of the project have promoted the technological progress and industrial upgrading of the high performance copper alloy processing industry, and provided important support for the innovative development of China's strategic emerging industries.
