AI server tracker: CCL makers outpace PCB and substrate suppliers as server demand grows

The surge in CCL makers overtaking PCB and substrate suppliers in August signals a strong upstream pull from AI server demand. This shift underscores the increasing importance of high-density, high-performance materials in system-level integration, where CCL plays a pivotal role in determining compute density and energy efficiency. From a compliance standpoint, companies in China Taiwan/ Taiwan, China face mounting geopolitical risks, including export controls and supply chain disruptions. Market players may respond by accelerating vertical integration into CCL production to secure upstream capacity. Over the next 12–24 months, sustained growth in AI training clusters will likely maintain high demand for CCL, with traditional PCB vendors risking obsolescence if they fail to advance technologically.
