两大PCB电子材料巨头，涨价！

Core Viewpoint - Two major electronic materials companies have announced price increases for their products, driven by rising raw material costs and supply shortages, impacting the PCB industry significantly [2][3]. Group 1: Price Increases - Resonac, a leading supplier of CCL and bonding materials, will raise prices by over 30% starting March 1, citing ongoing shortages and price hikes of key raw materials like fiberglass, epoxy resin, and copper foil [2]. - Mitsubishi Gas Chemical has also announced a 30% price increase for its entire range of electronic materials, effective April 1, 2026, including CCL, prepreg, and CRS [3]. Group 2: Market Trends - The demand for CCL is expected to rise due to the upgrade of traditional servers and the penetration of AI servers, with CCL accounting for approximately 30% of PCB raw material costs [2]. - The global PCB market is projected to grow at a compound annual growth rate (CAGR) of 5.40% from 2024 to 2028, with the server/storage sector expected to grow at 13.6% [2]. Group 3: Material Specifications - The upgrade of PCBs and CCLs to M8/M9 standards is driven by the stringent requirements of AI infrastructure for data transmission loss [4]. - Key materials for AI PCBs include quartz fiber for electronic cloth, HVLP4/5 for copper foil, and PCH and PTFE resins for their excellent dielectric properties [4].
