PCB的催化又来了，LPU板层数又翻一倍 先看英伟达怎么说，"多跨越一个芯片，就多跨越一个接口，多跨越一个接口，就多增加延迟"。 所以LPU架构、正交背板架构、COWOP架构，还有一些现在并不知道的技术升级，是必然会发生的。 每个架构背后的逻辑，都是尽可能去减少芯片之间的传输距离，芯片堆叠多了，必然管脚会变得极其复杂，PCB 的加工难度、层数、精密度会极大程度增加，价值 PCB的催化又来了，LPU板层数又翻一倍 先看英伟达怎么说，"多跨越一个芯片，就多跨越一个接口，多跨越一个接口，就多增加延迟"。 每个架构背后的逻辑，都是尽可能去减少芯片之间的传输距离，芯片堆叠多了，必然管脚会变得极其复杂，PCB 的加工难度、层数、精密度会极大程度增加，价值量也会极大程度增加。 所以LPU用的50多层板单价至少四五万，70多层的正交背板单价能到三四十万。 PCB在整机柜中的价值量，从最初8卡服务器的1.5%，逐步提高到5%以上，未来有望到8%以上。 行业观点保持不变：产能极度紧缺，格局非常稳定。 #重点推荐：胜宏科技、沪电股份、鹏鼎控股、生益科技、生益电子等 新逻辑：载板今年必然还会涨价，已经成为制约芯片生产的有一大瓶颈，台 ...
