NVIDIA Tests M10 for AI Racks
💡NVIDIA's M10 supply shift opens China PCB sourcing for AI infra builders
⚡ 30-Second TL;DR
What Changed
NVIDIA and Shulun Shares testing M10 CCL based on Guo Mingxi's supply chain intel.
Why It Matters
Diversifying suppliers reduces NVIDIA's dependency on Taiwan, boosting China supply chain role in AI infra. Could lower costs via Low Dk-2 material shift, aiding scalable AI racks.
What To Do Next
Track Shulun Shares' Q1 2026 M10 samples for AI rack PCB prototyping opportunities.

Web-grounded analysis with 8 cited sources.
🔑 Enhanced Key Takeaways
- •M10 CCL represents an evolution from M9 materials, incorporating advanced quartz fiber fabric for lower dielectric constant and thermal expansion to support 224 Gb/s signaling in Rubin CPX and LPX midplanes[5][6].
- •Shulun Shares' 52-layer M9 Q-glass PCBs, already in use for LPX inference cabinets, integrate liquid-cooling cold plates and RealScale connectors for 256 LPUs per rack[5].
- •NVIDIA's LPX racks are positioned as inference complements to high-end Rubin GPUs, targeting long-context reasoning and real-time video/speech generation workloads[5].
🛠️ Technical Deep Dive
- •M9/M10 CCL uses quartz fiber fabric for reduced dielectric constant (Dk) and coefficient of thermal expansion (CTE), enabling 20–36+ layer stack-ups with heavy copper routing for SI/PI at 224 Gb/s PAM4 signaling[5][6].
- •52-layer PCBs in LPX support dense LPU integration (256 per rack), power delivery, high-speed signal routing, blind-mate interconnects, and mounting for liquid-cooling cold plates[5].
- •Material upgrades from M8 to M9 address insertion loss, eye-diagram integrity, and thermal management in NVLink 6 racks achieving 260 TB/s aggregate bandwidth[6].
