01Summary
Current AI chips face transmission bottlenecks at 200Gbps per lane, prompting a shift toward PTFE due to its superior signal efficiency. However, PTFE's poor adhesion and soft texture make fabrication difficult, with estimated yields below 5%. The material remains in sample phase, and skepticism persists among suppliers. Despite challenges, some partners have secured equipment, with industry forecasts suggesting potential adoption by 2028–2030.
