- NVIDIA is supporting Unimicron's KF substrate expansion in Taiwan through a capacity reservation agreement.
- New capacity is expected to start coming online in the second quarter of 2027 and reach full scale by mid-2028.
- Unimicron is targeting high-end ABF substrates used in AI processors, servers and advanced packaging.
NVIDIA is backing Unimicron's expansion of KF substrate manufacturing in Taiwan under a capacity reservation agreement announced on October 21, 2026. The plan links Unimicron to NVIDIA's wider effort to expand substrate, packaging, testing and optical-engine capacity for rising artificial-intelligence demand.
Unimicron stock traded at 989 TWD on the Taiwan Stock Exchange at 05:30 UTC on Friday, October 30. The company remains exposed to the investment cycle for AI servers and accelerators, while the planned capacity is not expected to add output until 2027.
Capacity Arrives After Qualification
According to NVIDIA's announcement carried by GlobeNewswire, the Unimicron expansion should begin adding capacity in the second quarter of 2027 and reach full capacity by mid-2028. NVIDIA said its agreements with Unimicron, Ibiden and Samsung Electro-Mechanics are intended to support a 2.5-fold increase in substrate capacity over three years.
The timing leaves execution, equipment availability, customer qualification and production yields as the main factors for investors to watch. Capacity reservations can improve visibility, but they do not by themselves establish the eventual revenue or margin contribution for Unimicron.
ABF Demand Raises Competitive Stakes
TechSoda reported on October 7 that Unimicron is focusing on scaling high-end ABF production as AI processors require larger substrates with more layers and tighter manufacturing tolerances. The publication described Unimicron as having a broader product portfolio spanning ABF and BT substrates, HDI and conventional PCBs than some Taiwanese peers.
TechSoda identified Nan Ya PCB and Kinsus as major Taiwanese suppliers, with Ibiden and Samsung Electro-Mechanics as international competitors. It characterized Unimicron's strategy as scale-led expansion, while Nan Ya PCB is more concentrated on servers and networking and Kinsus is seeking a larger role in packaging-technology development.
Unimicron's Business And Position
Unimicron Technology manufactures and sells printed circuit boards, IC carriers, connectors and related electronic products, and also provides integrated-circuit testing and burn-in services. Its products include HDI, multilayer, rigid-flex and flexible PCBs as well as FCCSP, FCBGA and other package substrates, with operations across Taiwan, China, Asia and the Americas, according to the Unimicron website.
Based in Taoyuan, Taiwan, the company is a diversified substrate and PCB manufacturer. It competes with Nan Ya PCB and Kinsus in Taiwan and with Ibiden and Samsung Electro-Mechanics internationally, while its broader mix gives it exposure to both advanced AI packaging and conventional electronics.
