梳理AI供应链瓶颈：内存、ABF、CPO及地缘政治动态。
一些我感兴趣的TLDR新闻摘要： 1. $GOOGL（漏看了）也联合$NVDA投资了联发科，参与其39亿美元融资。Google/Nvidia在投资眼光上真是“山羊”（顶级），从$SPCX到Anthropic都是如此。 2. 三星电机披露了7.789亿美元的MLCC（多层陶瓷电容器）订单；$CAPA（新MLCC ETF）也为无法访问韩/日/台市场的投资者提供了敞口。但关键在于，每个加速器所需的MLCC数量增加，可能预示着未来比人们预期更极端的瓶颈。 3. 中国渠道调查显示：行星滚柱丝杠、6D力传感器和灵巧手难以实现国产替代。其中行星滚柱丝杠的国产替代率最低。例如$SHA0.DE做行星滚柱丝杠。只是听听护城河挺有意思。 4. 据报道，三星约70%的内存产能已锁定至2031年/商品DRAM也陷入短缺 - 首尔经济日报。TrendForce预计2026年Q3服务器DRAM合约价环比上涨13-18%。SK海力士也公开表示内存短缺将持续至2030年。 5. $CXMT已开始小批量生产HBM3E，并据称实现了LPDDR6的大规模量产。这对传统DRAM短缺的暗示更为积极。 6. 思科在台湾SEMICON表示共封装光学(CPO)已准备好大规模部署；可插拔模块仍将是市场主流。$MRVL也表示客户正积极规划早在2027年扩大光学部署。 7. 闻泰科技 -> 收购安世半导体 -> 荷兰政府实际上剥夺了闻泰的控制权 -> 闻泰正通过中国法院反击。但安世3亿美元资产被冻结。当然还有更多地缘政治戏剧，总是很娱乐。$AAPL也明确指控OpenAI销毁关键证据...（更多乐子） 8. 关于SOI（绝缘体上硅）衬底$SOI的ASP（平均售价）上涨描述不多，但他们现在有10+客户参与LTA（长期协议），$2亿营收被称为“底线”，评论称客户更关心获得晶圆而非制造地。所以基本上随着硅光子技术在2027年起飞，现在进入产能预留阶段。 9. 一些渠道调查显示高功率MOSFET和大面积TVS二极管的交货期高达~52周。（$STM据报道也在8月23日实施了2026年第三次涨价） 10. 传统封装产能可能在2027年面临超过20%的缺口，“引线键合设备”成为主要瓶颈，本周早些时候已覆盖过，受益者如... 11. 声称所有六大ABF供应商2026年订单已满，交货期12-14个月，部分供应商拍卖剩余产能；$NVDA、$AMD和超大规模客户锁定ABF产能至2028年，并推动供应商规划2029-30年扩产。像Kinsus (3189)、Unimicron (3037)、南亚PCB (8046)、Ibiden (4062)等名字大概都很开心。 12. CCL（覆铜板）主导的层压板产品再次涨价10%-20%，今年第7次涨价（如建滔）。行业估计HVLP4铜箔短缺在2026年约48%/2027年43%，而Low-Dk/T-Glass交货期已延长至30周以上。 13. “(GaAs)衬底材料和砷化镓外延源材料在2026年第三季度也面临新一轮涨价，据报道比限制初期高出5到6倍。”“中国最近放宽了一些衬底出口管制”，但据digitimes称“InP衬底严重短缺”。只是些$AXTI相关更新。 14. $AMD和$AVGO据报道预订了PowerTech计划的大部分FOPLP产能，早于2027年中大规模量产。 15. $INTC考虑使用$INTC代工生产HBM4E基底芯片。但$SKHY直接回应称“部分内容与事实不符”。 16. “OpenAI囤积数万台$AAPL Mac mini和Mac Studio”用于强化学习。Anthropic也从$AMZN租赁Mac mini单元。Tim Cook退休有点可惜，但老哥表现确实“山羊”（顶级）。只是些随机有趣的笔记。
英文原文
Just some TLDR news I found interesting: 1. $GOOGL (missed this) also invested in Mediatek alongside $NVDA for their $3.9B raise. Google/Nvidia are goats with investments you look at $SPCX to Anthropic. 2. Samsung Electro-Mechanics discloses $778.9M MLCC deal / $CAPA (new MLCC ETF) also gives exposure now for folks without Korea/Japan/Taiwan market access. But thing is more accelerators x MLCCs per accelerator might indicate a more future extreme bottleneck than people expect. 3. China channel checks state: planetary roller screws, 6D force sensors, and dexterous hands resist domestic substitution. Then planetary roller screw as the top with lowest domestic substitution rate. eg. $SHA0.DE for planetary. Just interesting to hear moats I guess. 4. Samsung reportedly has ~70% of memory production capacity committed through 2031 / commodity DRAM has also fallen into short supply - Seoul Economic Daily. TrendForce expects server DRAM contract prices to rise 13-18% QoQ in 3Q26 SK Hynix also publicly stated the memory shortage lasts through 2030. 5. $CXMT has begun producing HBM3E in small quantities and reportedly claimed mass production of LPDDR6. Implications are even more positive for legacy DRAM shortages. 6. Cisco at SEMICON Taiwan said CPO is ready for mass deployment; pluggable modules will remain the market mainstay. $MRVL also said customers are actively planning scale-up optics deployments as early as 2027 7. Wingtech -> bought Nexperia -> Netherlands effectively removed Wingtech’s control -> Wingtech is fighting back through Chinese courts. But Nexperia got $300m of their assets frozen. More geopolitical drama of course, always entertaining. $AAPl also explicitly accused OpenAI of destroying crucial evidence... (for more fun) 8. Not much description around ASP hikes regarding SOI substrates $SOI, but they now have 10+ customers involved with LTAs, $200m revenue described as a "floor", comments about customers more concerned about obtaining wafers than where they are manufactured. So basically moving into capacity reservation now stages as silicon photonics takes off in 2027. 9. Some channel checks put lead times for high power MOSFETs and large area TVS diodes as high as ~52 weeks. ($STM also reportedly implemented its 3rd 2026 price increase on August 23) 10. Traditional packaging capacity could face a deficit exceeding 20% by 2027" with "wire bonding equipment" emerging as the primary bottleneck", covered this earlier this week with beneficiaries like 11. Claims that all six major ABF suppliers are booked for 2026, with 12-14 month lead times and some suppliers auctioning remaining capacity; $NVDA, $AMD and hyperscalers locking ABF capacity through 2028 and pushing suppliers to plan 2029–30 expansions. Names like Kinsus (3189), Unimicron (3037), Nan Ya PCB (8046), Ibiden (4062), etc are all probably happy. 12. CCL leading laminated board products increased by another 10%-20%, 7th price hike this year (eg. Kingboard). Industry estimates put the HVLP4 copper-foil shortage at ~48% in 2026 / 43% in 2027, while Low-Dk/T-Glass lead times have stretched beyond 30 weeks. 13. "(GaAs) substrate materials and gallium epitaxial source materials are also facing another round of price increases in the third quarter of 2026, reportedly 5 to 6 times higher than at the early stage of the restrictions." "China has recently eased some substrate export controls" but there's a "severe InP substrate shortage" per digitimes. Just some $AXTI related updates 14. $AMD and $AVGO reportedly booked most of Powertech's planned FOPLP capacity ahead of mid-2027 mass production 15. $INTC considering $INTC foundry for HBM4E base dies. But $SKHY responded directly that "some of the content is different from the facts". 16. "OpenAI Hoarding Tens Of Thousands Of $AAPL Mac mini and Mac Studio" for reinforcement learning. Anthropic has been renting mac mini units from $AMZN as well. Kinda sad Tim Cook retired, but dude had a goated run. Just random interesting notes

NVDA 推进 800V
$NVDA 正在积极推进 800V，这对今天来说是一个相当大的信号。 “2026 年 4 月 22 日，NVIDIA 已经与主要韩国电力设备公司展开讨论，探索基于约 800V 直流（DC）系统设计数据中心基础设施。” 之前提到的 Nvidia 合作伙伴包括：Infineon、$TXN、$STM、$NVTS、Delta、Flex、$ETN、Schneider 和 $VRT。 早就知道他们在往这个方向推了，但……看起来现在真的是 Nvidia 在主导。 我个人对 $NVTS 的敞口很小，因为它们在 800V DC 的 SiC / GaN IC 方面暴露很高。 我知道其他人更喜欢 $VICR 作为敞口。
英文原文
$NVDA actively pushing to 800V, and today was a pretty big signal. "On April 22, 2026, NVIDIA has initiated discussions with major South Korean power equipment companies to explore designing DC infra based on an approximately 800V direct current (DC) system" Previous named Nvidia partners include: Infineon, $TXN, $STM, $NVTS, Delta, Flex, $ETN, Schneider, and $VRT. It's been known they're been pushing for this but... looks like Nvidia is really driving it. Personally very small exposure to $NVTS since they're they have a high exposure for SiC/GaN ICs for 800V DCs. I know others really liked $VICR for exposure.

马斯克指出Optimus三大瓶颈：智能、手部及制造，暗示美韩主导核心部件。
$TSLA Optimus 瓶颈 TLDR - Elon Musk 采访： “人形机器人只有三件难事”： 1. 现实世界智能（例如 Dojo，$NVDA，三星机电） 2. 手部（~ 可能是 $VPG） 3. 规模化制造（~ 浙江华正，宁波拓普，Everwin） 关于手部： Elon 声称 $TSLA Optimus 的人手自由度比其他机器人更多。 特斯拉“设计了定制执行器、齿轮、功率电子、控制、传感器。这方面没有供应链。” Elon 在采访中基本上强调手部是机器人最涉及知识产权且最复杂的部分。Elon 重申特斯拉解决了中国其他人形机器人今天尚未解决的问题。 这使得西方制造商参与这一特定 BOM 部分的可能性略微增加（相比此前报道的中国供应链）。 关于现实世界智能方面： Elon 聚焦于：“惯性测量、GPS 信号、其他数据，将其与视频结合，主要是视频，然后输出控制命令” - 训练 ~ Cortex / Dojo 供应商，$NVDA。 - 视频与视觉：三星机电？ - IMU + GPS：$STM 或博世？ 规模化制造： 正如朝鲜日报报道，身体部分可能来自中国供应链。 从推理来看似乎是： 大脑 + 高端组件 = 美国/韩国 身体是中国（三花，拓普等）。 但再次强调，这并未确认，只是可能的供应链映射。 无论如何，Elon 为投资者指出了人形机器人量产过程中的三个瓶颈投资方向。
英文原文
$TSLA Optimus Bottleneck TLDR - Elon Musk Interview: "There's only three hard things for humanoid robots": 1. Real World Intelligence (eg. Dojo, $NVDA, Samsung Electro-Mechanics) 2. The Hand (~ possibly $VPG) 3. Scale Manufacturing ( ~ Zhejiang Huazheng, Ningbo TuoFu, Everwin) For the hand: Elon claimed that $TSLA Optimus has the more degrees of freedom with a human hand than other robotic humanoid. Tesla "designed custom actuators, gears power electronics, controls, sensors. There is no supply chain for this." Elon basically focused on the hand is the most IP-sensitive and complex part of the robot during the interview. Elon reiterated that Tesla solved issues with the hand that no other humanoids in China have today. This makes things slightly more probable that Western manufacturers are involved (compared to Chinese supply chains from earlier reports), with this part of this specific BOM. For the Real World Intelligence Aspect: Elon focused on: "Inertial measurements, GPS signals, other data, combining that with video, primarily video, and then outputting the control commands" - Training ~ Cortex / Dojo suppliers, $NVDA. - Video & Vision: Samsung Electro-Mechanics? - IMUs + GPS: $STM or Bosch? Scale Manufacturing: Likely Chinese supply chains as reported, by Chosun for the body. From inference looks like: Brain + high-end components = US/Korean Body is Chinese (Sanhua, Tupou, etc). But again, this is not confirmed, just possible supply chain mapping. Regardless, Elon gave investors three bottlenecks to invest in for the humanoid ramp.
