NVIDIA is testing a new glass-free hydrocarbon (HC) resin-based copper-clad laminate (CCL) for its Rubin Ultra NVL576 switch tray PCBs, potentially replacing the previously tested PTFE-based CCL. This could improve manufacturing yields and efficiency while meeting high-frequency electrical requirements.
NVIDIA's material testing signals a potential shift in advanced PCB materials, with Shengyi Technology poised to benefit and Chinese suppliers gaining traction.
