The self-sufficiency rate for standard stamped lead frames in the domestic market is already at a relatively high level, and local manufacturers have well-established supply capabilities; however, ultra-thin and ultra-fine-pitch etched lead frames, as well as automotive-grade high-reliability frames, have previously relied heavily on supplies from overseas and Taiwanese manufacturers. Over the past two years, leading domestic enterprises have continued to undertake technological upgrades and expand production capacity, resulting in a year-on-year increase in the self-sufficiency rate for high-end products. With downstream packaging and testing companies showing a growing preference for localised procurement within their supply chains, domestic manufacturers are now entering a window of opportunity for product upgrading.
