Core Viewpoint - The company is in the process of internal validation for its PCB board technology, specifically for the M9 model, which shows promising initial results but faces challenges in scaling and cost control [1] Group 1: Internal Validation Process - The company reported that during internal validation, it achieved over 8000 hole processes on a PCB board with a thickness of 3.5mm and a diamond micro-drill diameter of 0.25mm [1] - These results are preliminary and indicate potential but require further verification regarding process matching and stability [1] Group 2: Product Development and Market Uncertainty - The company needs to develop corresponding products tailored to various PCB board structures and thicknesses, emphasizing the importance of ongoing optimization [1] - There is significant uncertainty regarding the ability to achieve scalable revenue in the PCB hole processing sector, which is contingent on industry development and market conditions [1]

Group 1 - The core business of the company is the research, production, and sales of ultra-high precision, high precision cutting tools, and superhard material products [1] - Recently, certain products, particularly diamond micro-drills used in PCB board hole processing, have gained attention; however, these products are still in the research and testing phase and have not generated revenue [1] - From January to September 2025, the diamond micro-drill achieved revenue of 9.5265 million yuan in other application areas [1] Group 2 - For the same period, the revenue from screw and RV reducer processing tools and diamond heat sink products is very small, accounting for no more than 1% of the company's total revenue [1] - The impact of these products on the company's overall revenue for 2025 is limited, and their development prospects are influenced by multiple factors, including industry trends and market conditions, which introduce uncertainty [1] - The relevant market is still in the early cultivation stage, and future market expansion may face challenges, including potential lower-than-expected downstream demand [1]
