Shengyi Technology is the leading supplier for these evaluations, providing the SG1030N and SIF09 materials, both of which still contain small amounts of PTFE. Nvidia may eventually test woven-glass-reinforced HC PP to further optimize manufacturability, provided the materials can meet a 0.4 dB/in loss requirement. These tests are preliminary and have not yet resulted in a final material selection for the Rubin Ultra lineup.

Nvidia Tests Hydrocarbon Resin for Rubin Ultra NVL576 to Boost PCB Yields
Tech21 days ago
The 2H27 mass production timeline for a new 8 rack interconnected server involves switching to a specific type of glass-free copper-clad laminate (CCL) to improve manufacturing efficiency. Supply chain checks by analyst Ming-Chi Kuo indicate that Nvidia is evaluating hydrocarbon resin-based CCL, paired with hydrocarbon-based polypropylene (PP), for the switch tray printed circuit boards of its Rubin Ultra NVL576. This combination is intended to replace glass-free PTFE-based CCL to increase production yields while maintaining high-frequency electrical performance, which analysts say exceeds M10 and M9 specifications though it trails the original PTFE solutions.
