Summary of Conference Call Records Industry Overview - The records focus on the **AI server PCB (Printed Circuit Board)** industry, highlighting the advancements in drilling technology and materials used for manufacturing PCBs for AI applications [1][2][3]. Key Points and Arguments 1. **Increased Demand for High-Aspect-Ratio Drill Bits** The demand for drill bits has surged due to the production of AI servers, with thickness requirements increasing from 4.0 mm in traditional servers to 6.0 mm and even 8.0 mm in AI servers. The aspect ratio has also increased from 20:1 to as high as 40:1, leading to a significant rise in drill bit prices, which are approximately 10 times higher than traditional bits, but with a yield rate of only around 50% [2][3]. 2. **Material and Cost Implications** AI server PCBs primarily use **Ma Jiu** materials, which are more expensive than traditional **Ma Liu** or **Ma Qi** materials. For instance, drill bits for 6.0 mm thickness cost about 4 RMB each, while those for 8.0 mm thickness can exceed 20 RMB, with the latter still in the prototyping phase [1][5]. 3. **Drilling Techniques and Strategies** High-precision drilling requires a combination of short and long drill bits. Common strategies include using three to four short bits with one long bit or two short bits with a medium-length bit and one long bit. PCB manufacturers select the optimal combination based on their specific needs and testing results to achieve the highest yield [7][9]. 4. **Supplier Landscape** Major suppliers in the AI drill bit market include **You Neng**, **Jingzhou**, **Ding Tai**, and **Classic**, with You Neng being the technology leader and Ding Tai having the largest production capacity. The main PCB manufacturers for AI servers include **Hu Shi**, **Shen Nan**, **Dongguan Mingpu**, **Sheng Yi Technology**, and **Jing Wang**, all of which have begun mass production [12][13]. 5. **Market Supply and Production Challenges** The market is currently facing a supply shortage, particularly for the 8.0 mm drill bits, which are still in the prototyping stage. Only a few manufacturers can produce drill bits that meet the required specifications, leading to tight supply conditions [6][24]. 6. **Impact of Tungsten Price Increases** The rising prices of tungsten significantly affect production costs, especially for milling tools. While drill bits only have tungsten at their tips, the overall cost increase is expected to be around 25% due to the rise in tungsten prices. This will impact pricing strategies for AI products, although existing contracts may delay immediate price adjustments [22][25]. 7. **Drilling Technology Comparison** Mechanical drilling and laser drilling serve different purposes and cannot fully replace each other. Mechanical drilling provides smoother holes and is essential for multi-layer boards, while laser drilling is limited to blind holes and has quality concerns [20][23]. 8. **Future Production Capacity and Expansion** Current production capacity for AI-related products needs to double to meet market demand. Many companies are actively expanding, but challenges remain in achieving mass production, particularly in high-end sectors [24][28]. Additional Important Insights - The pricing model for drill bits and PCBs is typically negotiated annually, with suppliers gaining more negotiating power due to increased demand and rising material costs [25]. - The transition from traditional to AI drill bits requires significant equipment updates, which can take two to three months for new equipment to be purchased and calibrated [32]. - The performance of drill bits varies significantly based on the materials used and the specific manufacturing parameters set by different PCB manufacturers, leading to varying wear rates [10][11]. This summary encapsulates the critical aspects of the AI server PCB industry as discussed in the conference call records, providing insights into market dynamics, technological advancements, and production challenges.
