ACCM Introduces Celeritas SMC: A Production-Ready, Silicon-Matched Core for Advanced Packaging
Advanced Chip and Circuit Materials (ACCM) today introduced Celeritas SMC (Silicon-Matched Core), a production-ready core for advanced IC substrates engineered to match the in-plane coefficient of thermal expansion of silicon while running on established organic-substrate manufacturing lines. Available now from ACCM's Wisconsin facility, the material is designed for large-body chiplet packages, embedded-bridge architectures, and other advanced packages in which conventional organic cores face growing warpage and thermomechanical reliability limits.
The Thermal Mismatch Problem Constraining Large-Format AI Chips Has Been Solved: ACCM's Celeritas HM50 & HM001 Address Warpage, Package Bow, and Signal Loss
Advanced Chip and Circuit Materials today announces the commercial availability of Celeritas HM50 and Celeritas HM001, which eliminate the root causes of warpage, package bow, solder fatigue, and high-frequency signal loss in large-format AI accelerators and advanced chip packaging architectures. Celeritas HM50 is a negative CTE (-8 PPM/°C) material and Celeritas HM001 is a near-zero CTE material. Used together in a single stackup, they bring board CTE below 10 ppm/°C while simultaneously delivering Tier 9 electrical performance.
Advanced Chip and Circuit Materials Introduces CeleritasSF & CeleritasBU Products for Ultra-High-Speed, Buildup, and UHDI Printed Circuit Boards
Advanced Chip and Circuit Materials Inc. (ACCM), a US-based manufacturer of skew free, ultra-thin copper-clad laminates and dielectric prepreg materials used to fabricate high layer count PTH, Buildup and UHDI multilayer printed circuit boards (PCBs), today announced the introduction of the CeleritasSF and CeleritasBU series of laminates and prepregs, which enable PCIe Gen 6 & 7 and data rates of 224 Gb/s per channel.
