AI Server Demand Drives Substrate Expansion

FCBGA substrates are high-density package substrates used to mount CPUs, GPUs and other high-performance chips. With AI server buildouts accelerating worldwide, demand for advanced package substrates has risen sharply, and the Sejong investment positions Samsung Electro-Mechanics to supply this segment.

The company operates production bases in Korea and Vietnam, and the Sejong site is a key location for its substrate business. The 4.27 trillion won figure was stated in the filing and reflects the company's largest commitment to date in this product area.

Scaling for the AI Supply Chain

Package substrates sit between the semiconductor chip and the mainboard, handling signal and power connections for high-pin-count devices. As AI accelerators grow in size and complexity, substrate makers have become an increasingly important link in the AI hardware supply chain, alongside foundry and memory suppliers such as Samsung Electronics and SK hynix.

The investment is expected to strengthen Samsung Electro-Mechanics' position against global competitors in the package substrate market, though specific timelines for capacity ramp-up were not detailed in the disclosed materials.

The claim that Samsung Electro-Mechanics will invest 4.27 trillion won in Sejong FCBGA production to respond to AI server demand is True.
