Core Viewpoint - The article discusses the emergence of CoWoP (Chip-on-Wafer-on-PCB) technology as a potential alternative to CoWoS (Chip-on-Wafer-on-Substrate) and CoPoS (Chip-on-Panel-on-Substrate), highlighting its advantages and disadvantages in semiconductor packaging [1][12][14]. Summary by Sections CoWoS Overview - CoWoS involves a three-stage packaging process where dies are connected to an interposer, which is then connected to a packaging substrate, followed by cutting the wafer to form chips [7]. CoPoS Technology - CoPoS replaces the wafer with a panel, allowing for a higher number of chips to be accommodated, thus improving area utilization and production capacity [11]. Introduction of CoWoP - CoWoP eliminates the packaging substrate, allowing chips to be directly soldered onto the PCB, which simplifies the design and reduces costs [12][14]. Advantages of CoWoP - CoWoP reduces packaging costs by eliminating the expensive packaging substrate, leading to lower material costs and reduced complexity [14]. - It offers shorter signal paths, enhancing bandwidth utilization and reducing latency for high-speed interfaces like PCIe 6.0 and HBM3 [15]. - The absence of a packaging cover allows for better thermal management options, which is beneficial for high-power AI chips [15]. Disadvantages of CoWoP - The direct attachment to the PCB increases the requirements for PCB reliability and precision, as the tolerance for errors is significantly reduced [16]. - The lack of protective packaging raises concerns about reliability under thermal cycling, mechanical stress, and transport vibrations [16]. - Successful implementation requires close collaboration between chip packaging and PCB manufacturing from the design stage, increasing supply chain management complexity [16]. Conclusion - CoWoP technology is considered aggressive and presents significant challenges, indicating that it may not have an immediate impact on all PCB companies in the short term [17].

Core Insights - Google Gemini's daily active users (DAU) are significantly lower than ChatGPT, yet its token consumption is six times higher than that of Microsoft, primarily driven by search products rather than the Gemini chat feature [3][7][8]. User Metrics - As of March 2025, ChatGPT has over 800 million monthly active users (MAU) and 80 million DAU, while Gemini has approximately 400 million MAU and 40 million DAU [6][8]. - The DAU/MAU ratio for both ChatGPT and Gemini stands at 0.1, indicating similar user engagement levels [6]. Token Consumption - In Q1 2025, Google’s total token usage reached 634 trillion, compared to Microsoft’s 100 trillion [8]. - Google’s token consumption for Gemini in March 2025 was about 23 trillion, accounting for only 5% of its overall token usage [7][8]. - Each MAU for both ChatGPT and Gemini consumes approximately 56,000 tokens monthly, suggesting comparable user activity levels [8]. Financial Impact - Google’s cost for processing these tokens in Q1 2025 was approximately $749 million, representing 1.63% of its operating expenses, which is manageable compared to traditional search costs [8]. - Barclays predicts that Google will require around 270,000 TPU v6 chips to support current token processing demands, with quarterly chip spending expected to rise from $600 million to $1.6 billion [8].

Core Viewpoint - The H20 market is experiencing high demand, with potential buyers urged to act quickly due to limited supply and significant interest from Chinese companies [1][4]. Supply and Demand - Current H20 supply consists of existing inventory, with estimates ranging from 300,000 to 400,000 units or 600,000 to 1,000,000 units, indicating a limited availability [1]. - Chinese enterprises are rapidly purchasing H20, with large companies submitting substantial applications [1]. Technical Aspects - Discussions on transitioning from H200 (or H800) to H20 suggest the use of "point cutting" technology for hardware downscaling, differing from previous software methods [2]. - There are indications that after the ban on H20, Nvidia considered reverting H20 back to H200, but the high costs led to abandonment of this plan [2]. Market Impact - The release of H20 is expected to negatively impact certain sensitive companies, although specific names are not disclosed [3]. - Once the existing H20 inventory is sold out, it is unlikely that new H20 units will be produced, as Nvidia is focusing on the Blackwell series [3]. Buyer Recommendations - Potential buyers are advised to act without hesitation, as future availability may become constrained [4].
