The leading company in innovation and entrepreneurship remains strong, and the China Merchants CSI Scientific Innovation and Entrepreneurship 50 ETF (588300) is aiming for a weekly 7 consecutive gains! On May 22, boosted by Morgan Stanley's breakdown of Nvidia's Rubin rack findings, multiple stocks in MLCC, PCB, and CPO surged. Near the close, CCTC rose over 17%, Times Electric, Shenghong Technology, and Huada Jiutian increased over 14%, 12%, and 11% respectively, Tianfu Communication and Shenye Electronics rose over 9%, Xinyi Sheng increased over 7%, and the China Merchants CSI Scientific Innovation and Entrepreneurship 50 ETF (588300) rose over 3%, hitting a weekly surge of 7 consecutive gains! In terms of news, Morgan Stanley's breakdown of the bill of materials for Nvidia's next-generation Rubin rack shows that its rack value reassessment is not solely driven by GPUs; rather, the value increase of PCB content is the largest, growing by 233%. According to Guojin Securities' calculations, the PCB value of Nvidia's VR200 cabinet reaches USD 116,000, more than tripling compared to the GB300 (USD 35,000). At the same time, according to TrendForce, the Nvidia VR200NVL72 server will use approximately 600,000 MLCCs, over 30% more than the existing GB300 platform, covering voltage specifications from 2.5V to over a thousand V. Morgan Stanley also estimates that the value of PCB, MLCC, ABF, power supply, and cooling in the VR200 Rubin cabinet has significantly increased, viewing NVIDIA NVL576 and subsequent multi-rack architectures as acceleration points for CPO, with the optical engine/GPU attach rate potentially rising from 2 to 4 to over 17 or even 35. 【What are PCB, CPO, and MLCC?】 PCB refers to printed circuit boards, used to connect various electronic components; CPO is co-packaged optical technology, which can directly package optical modules and chips together, mainly used in data centers to save energy and speed up processes; MLCC stands for "multi-layer ceramic capacitors," akin to "mini power banks" in electronic devices, primarily used to stabilize voltage and filter noise. Guojin Securities points out that the current iteration of AI inference bottlenecks and architectural evolution is driving a fundamental leap in PCB value positioning. Currently, industry capital expenditures are growing rapidly, with leading domestic manufacturers proactively laying out high-end production capacity; for example, Shenghong Technology is expected to grow by 693.41% year-on-year in 2025 and 389.59% in Q1 2026, indicating that the industry is entering a growth expansion cycle. Under heavy capital investment, long production expansion cycles, and high customer certification barriers, leading manufacturers are securing supply chain advantages by locking in major North American CSP clients in advance, leading to a continuous increase in industry concentration. Regarding CPO, Jiguotai Haitong, in the context of an AI demand explosion, optical interconnect has become an important factor determining the performance and utilization of AI infrastructure. The growth rate of the optical communication industry is expected to continue to exceed the overall Capex growth rate. Among them, CPO, as the next-generation high-density, low-power optical interconnect solution, benefits from the expansion of AI cluster scales and the bandwidth upgrade of switching chips, with continuous increases in industry attention and order expectations It is expected to become an important incremental direction in the optical communication sector.
