同时国海证券还提到，在算力产业快速发展的背景下，金刚石的功能化应用也在不断突破。随着人工智 能竞赛进入白热化，算力需求呈指数级增长，芯片散热已成为制约行业发展的关键瓶颈。 国海证券2月25日指出，本次超硬材料概念全线走强的核心驱动力，来自AI服务器需求爆发带来的PCB 钻针量价齐升逻辑。随着英伟达在新产品Rubin中确定使用M9级覆铜板，PCB行业正面临前所未有的加 工挑战。据了解，M9级覆铜板中使用了石英布（Q布），其主要成分为硅，远超传统玻璃布的硬度。 与此同时，PCB层数也从16层增至24层，传统硬质合金钻针的加工寿命大幅缩短。数据显示，涂层钻针 在M9材料上的加工寿命仅为150-200孔/针，较普通材料下降80%。 南方财经2月27日电，培育钻石概念午后拉升，冲击"四连涨"。成分股中，沃尔德触及涨停，国机精工 涨超6%，力量钻石、四方达等跟涨。 ...
