In the production workshop of the Semiconductor Packaging Materials Division of Jinchuan Niedu Industrial Company, the fully automated forging production line operates at a speed of 1,000 times per minute, producing uniquely shaped copper strips with a thickness of just 0.38 millimeters.
These copper strips will serve as the core material for integrated circuit lead frames, supporting the structure of chip packaging.

With the rapid growth of new energy vehicles, 5G communication, and the integrated circuit industry, lead frames face the challenge of being light, thin, strong, and conductive. In order to meet the demand for high-end copper strips for lead frames, Jinchuan has upgraded its technology, transitioning from the mid-low end to the high end. Through improvements in forging technology and alloy ratios, the company has successfully manufactured high-quality uniquely shaped copper strips that meet the stringent material performance requirements of integrated circuit packaging.
