1. Demand Pull for Drilling Equipment Due to PCB Upgrades
Demand Drivers: The rapid development of high-value-added PCBs (such as high-layer boards and HDI boards) for AI servers and high-speed network communications has led to an increase in the number of PCB layers (from 12 layers to over 18 layers) and a reduction in hole diameters (some below 0.1mm), significantly raising the requirements for drilling accuracy and efficiency. The upgrade of AI server PCBs has increased the unit consumption of drill bits (the lifespan of drill bits has decreased from 1000 holes to a few hundred holes), driving both the quantity and price of drilling equipment upwards (AI-related drilling machines are priced 20%-100% higher than ordinary equipment).
Market Size and Growth: The global PCB drilling equipment market is expected to reach $1.47 billion in 2024, with an anticipated increase to $2.399 billion by 2029 (CAGR 10.3%); the Chinese market accounts for over 56%, leading global growth. Drilling equipment constitutes 20%-21% of the value of PCB-specific equipment, making it the highest value segment in the industry chain.
2. Analysis of the PCB Drilling Equipment Industry Chain
The PCB drilling industry chain is divided into equipment manufacturing, consumable supply, and downstream applications:
-
Core Segments:
-
Drilling Equipment: Includes mechanical drilling (hole diameter ≥0.15mm) and laser drilling (hole diameter <0.15mm). Mechanical drilling is mainly used for high-layer boards, while laser drilling is used for HDI boards with micro blind holes/buried holes.
-
Key Consumables: Drill bits (such as PCB drill bits), with a global market size of $940 million in 2024, expected to reach $1.27 billion by 2031 (CAGR 4.4%).
-
Impact of Technological Upgrades:
-
The increased hardness of substrates for AI PCBs (such as Low DK third-generation quartz cloth) has led to accelerated wear of drill bits, resulting in a surge in demand.
-
The popularization of the MSAP (Modified Semi-Additive Process) has increased the demand for filling hole plating equipment, indirectly boosting the value of the drilling segment.
-
Industry Chain Bottlenecks: The production capacity of high-end laser drilling equipment is limited, and supply shortages may drive up equipment prices and accelerate domestic substitution.
3. Competitive Landscape of Players
The global drilling equipment market exhibits an oligopolistic competition, with a gradual increase in domestic production rates:
-
Global Landscape:
-
High-end Market: Dominated by Japan’s Mitsubishi Electric, Germany’s Schmoll, and France’s ESI, primarily supplying high-precision laser drilling equipment.
-
Mid to Low-end and Mechanical Drilling: Dominated by Chinese manufacturers, with Dazhong CNC leading the global market share (approximately 56.5% in China in 2024).
-
Positioning of Domestic Manufacturers:
-
Mechanical Drilling: High domestic production rate (>50%), with Dazhong CNC as the leader.
-
Laser Drilling: Low domestic production rate (<30%), primarily CO₂ laser drilling, with ultra-fast laser equipment relying on imports; domestic manufacturers like Dazhong CNC and Tianzhun Technology are accelerating substitution.
-
Consumable Landscape: In the drill bit sector, the global CR4 (Ding Tai Gao Ke, Jin Zhou Jing Gong, Japan’s Youneng, and Jian Dian Technology) holds a market share of 66.5%, with Ding Tai Gao Ke ranked first globally (26.5%).
4. Analysis of the Most Promising Players
Based on technological innovation, market share, and benefits from AI upgrades, the potential players are as follows:
-
Dazhong CNC (301200.SZ):
-
Advantages: The world’s largest PCB drilling equipment manufacturer, covering the entire technology route for mechanical and laser drilling; orders for AI-related equipment have doubled, with prices 20%-100% higher than ordinary equipment. They are laying out ultra-fast laser drilling technology, benefiting from the explosive demand for micro holes in HDI boards.
-
Potential Points: Stable market share in 2024, significant space for domestic substitution in laser drilling; the controlling shareholder Dazhong Laser provides synergy in the industry chain.
-
Ding Tai Gao Ke (301377.SZ):
-
Advantages: The global leader in drill bits (market share of 26.5%), with AI server drill bit sales accounting for 30.9% (coated drill bits), leading in micro hole diameter (≤0.2mm) technology.
-
Potential Points: Directly benefits from the expansion of AI server production, with upgrades in hard substrates further increasing drill bit consumption.
-
China Tungsten High-tech (000657.SZ):
-
Advantages: Its subsidiary Jin Zhou Jing Gong is the second-largest drill bit supplier globally (market share of 18%), with high customer certification barriers (6-12 months) and strong customer stickiness.
-
Potential Points: Deeply bound to leading AI PCB manufacturers, with ample production capacity flexibility.
-
Tianzhun Technology:
-
Advantages: Focused on the localization of laser drilling equipment, breaking through CO₂ laser technology and laying out ultra-fast lasers; benefits from the overflow of high-end PCB demand.
-
Potential Points: In the transition area of 100-120μm hole diameter, price increases in mechanical drill bits may drive the substitution of laser drilling.
5. Summary and Predictive Insights
Industry Chain Trends: PCB upgrades (high-layer and micro hole diameters) will continue to drive demand for drilling equipment, with mechanical drilling dominating in the short term, while the proportion of laser drilling is expected to accelerate (with a projected CAGR of over 15% for the laser drilling market by 2030).
Evolution of Competitive Landscape: Domestic manufacturers are breaking into the laser field from mechanical drilling, while limited foreign high-end production capacity provides a window for substitution; leading consumable companies benefit from customer stickiness and certification barriers.
Investment Potential Ranking:
-
Dazhong CNC: Comprehensive coverage of the entire technology route + order flexibility, solidifying its leading position.
-
Ding Tai Gao Ke: Directly benefits from the simultaneous increase in drill bit quantity and price, with significant potential for global market share growth.
-
Tianzhun Technology: A core player in the localization of laser drilling, with significant benefits from technological iteration.
Conclusion: In the AI-driven high-end PCB expansion cycle, the leaders in equipment and consumables within the drilling equipment industry chain are the most promising. Focus on players with leading technology and strong domestic substitution logic, among which Dazhong CNC and Ding Tai Gao Ke have stronger short-term explosive potential due to performance elasticity and supply-demand gaps.
