The Localization of High-Frequency PCBs: Import Dependence is Breaking, but Core Challenges in mmWave and AI Computing Persist
The longstanding industry perception that “the best high-frequency PCB materials must be imported” is undergoing a significant shift. Domestic suppliers have achieved large-scale substitution in mid-to-low frequency applications and made breakthroughs in specific advanced materials. However, the core technological battle for next-generation mmWave communications and top-tier AI computing substrates continues. I. The Evolving Landscape: From […]
