ACCM Expands US Manufacturing Capacity Across Four Advanced Materials Segments for AI Infrastructure
AI-summarised brief · reviewed before publication
Advanced Chip and Circuit Materials, Inc. announced a U.S. expansion of its Celeritas dielectric material production to support AI hardware. New laminate capacity of 20 million square feet per year will begin in January 2027, while prepreg and build‑up capacity will reach 87 million square feet per year by November 2026, with further increases planned in late 2027. The expansion covers four segments—ultra‑high‑speed skew‑free, low‑/negative‑expansion laminates, IC substrate/core materials, and build‑up materials—using halogen‑free, PFAS‑free components that bypass the conventional copper‑clad laminate chain. A second materials characterization lab will open in La Crosse, Wisconsin, in October 2026.
💡 Why It Matters
- · By adding U.S.
- · capacity for high‑performance, supply‑secure dielectric materials, ACCM removes a critical bottleneck in AI chip and networking design, enabling faster lead times and higher‑speed systems without relying on traditional copper‑clad substrates.
