NVIDIA reportedly tests PTFE for next-gen NVLink boards to reduce signal loss

Nvidia is reportedly considering the use of PTFE, commonly known as Teflon, for next-generation NVLink switch boards to address severe AI server signal loss. Industry sources indicate that PTFE wastes far less signal energy than current resins, though its non-stick properties, thinness, and complex processing requirements present significant manufacturing and yield challenges.
