Semiconductor package substrates · Localized FC-BGA for AI
Daeduck Electronics
A leading Korean substrate maker of high-performance FC-BGA and semiconductor package substrates, investing 800B+ KRW in high-layer-count substrates for AI accelerators and servers to localize the high-end substrates long led by Japan and Taiwan. It supplies Samsung and SK hynix and is expanding to overseas AI customers; FC-BGA is a high-value material whose unit price rises with more layers and larger area as AI-server and HBM demand grows. The watch points are the utilization of its large capacity investment and whether it wins overseas AI customers.
