Summary of Conference Call Notes Industry Overview - The discussion primarily revolves around the PCB (Printed Circuit Board) industry, focusing on the comparison between two types of materials: 二代布 (Second Generation Fabric) and Q 布 (Q Fabric) [1][2][16]. Key Points and Arguments 1. **Challenges with Q Fabric**: - Q Fabric faces significant challenges in PCB processing, particularly in drilling due to its high hardness, which drastically reduces the lifespan of mechanical drill bits from 2000 holes to about 150 holes [3][4]. - Laser drilling also suffers from poor wall quality, affecting subsequent copper plating [4][3]. 2. **Advantages of Second Generation Fabric**: - The second generation fabric is noted for its quality and stability, making it a more favorable option in PCB solutions compared to Q Fabric [1][16]. - Several CCR manufacturers are evaluating multiple suppliers of second generation fabric, indicating a shift in preference [16]. 3. **Market Demand and Supply**: - There is an anticipated increase in demand for second generation fabric, with projections suggesting usage could reach 1 million meters by mid-2026 [22]. - Initial supply constraints are expected to ease within a few months as production ramps up [15][22]. 4. **Material Upgrades**: - Copper foil is being upgraded from HVRP3 to HVRP4 to reduce roughness and improve electrical performance, addressing skin effect issues in high-speed signal transmission [10][1]. 5. **Future Product Development**: - Ruby's new architecture will increase layer counts from 22 to 26 and upgrade materials to enhance performance [30][1]. - The timeline for determining PCB materials and designs is critical, with decisions needing to be made 5-6 months prior to product launches [11]. 6. **Pricing Trends**: - Recent price increases for glass fabric by Red River Group (20%) are attributed to strategic choices rather than market demand alone [25]. - There has been no significant fluctuation in the prices of second generation and Q fabrics recently, with prices remaining stable [26]. 7. **Competitive Landscape**: - Companies like Panasonic are assessing the production capacity of second generation fabric suppliers, indicating a competitive environment [14]. - The potential for new entrants in the market is limited due to the need for strong technical capabilities [31]. 8. **Technological Challenges**: - The development of orthogonal backplanes is hindered by the need for high-temperature presses, which are currently limited in availability [6][8]. - PTFE materials face challenges in multi-layer applications due to their thermal properties [7]. 9. **Supply Chain Dynamics**: - Domestic companies are facing uncertainty in entering the supply chain, with limited visibility on future integration [21]. - The relationship between Korean companies and Luxembourg suppliers is noted, with ongoing evaluations of new suppliers [20]. 10. **Emerging Technologies**: - Google is shifting towards HDI designs in its TPU products to reduce material usage, indicating a trend towards more efficient designs [29]. Additional Important Insights - The transition from Q Fabric to second generation fabric is seen as a necessary evolution in the industry, with Q Fabric potentially becoming an upgraded version if its issues can be resolved [28]. - The overall sentiment in the industry suggests a cautious optimism regarding the adoption of new materials and technologies, with a focus on quality and reliability over aggressive expansion [17][18].
