>A technological revolution driven by AI and green manufacturing is reshaping the global electronics industry chain.
In the wave of global AI computing power explosion and electronic industry chain reconstruction, China’s PCB industry has become the core pillar of the global supply chain. The size of China’s PCB market is expected to exceed 412.1 billion yuan in 2024 and grow to 433.3 billion yuan by 2025, accounting for over 40% of the global total output value. However, behind the expansion of scale, the localization of high-end materials, environmental compliance, and technological upgrading are becoming a watershed for the survival of enterprises.

Ⅰ. Industry status: Leading the world in scale, accelerating high-end transformation
-The world’s largest market size: China has been the world’s largest PCB production base for five consecutive years, and is expected to contribute over 40% of the global production capacity by 2025. The Pearl River Delta industrial cluster (accounting for 40% of the national output value) has become the core engine.
-Significant upgrading of product structure: multi-layer boards dominate the market (accounting for 47.6%), HDI boards have increased their market share to 16.6% due to the surge in demand for 5G smartphones and AI servers, and flexible boards account for 15% driven by automotive electronics.
-Explosive growth of top enterprises: Shennan Circuit’s net profit increased by 63.88% in the first three quarters of 2024, and Guanghe Technology’s global share of server PCBs reached 12.4%, confirming its breakthrough ability in the high-end field.
Ⅱ. Industry Chain Analysis: A Dual dimensional Game of Cost and Technology
The Chinese PCB industry chain has formed a highly collaborative ecological network, but the upstream bottleneck problem is prominent:
Upstream (raw materials account for 60% of the cost)
-Copper clad laminate: The localization rate exceeds 70%, and the production will reach 1.17 billion square meters by 2025, but high-frequency and high-speed materials (such as ABF film) still rely on imports.
-Copper foil: Composite copper foil has experienced explosive growth, with an estimated market size of 29.15 billion yuan by 2025. Enterprises such as Longdian Huaxin are accelerating the mass production of 3 μ m ultra-thin copper foil.
Midstream (with obvious manufacturing layering)
-High end field: High rise boards with 18 or more floors and HDI boards with a line width of ≤ 20 μ m are led by Shennan Circuit and SysPCB, serving AI servers and automotive grade products.
-In the mid to low end sector, small and medium-sized enterprises are facing profit squeeze, with a gross profit margin of less than 15%.
Downstream (diversified demand explosion)
| Application Fields | Scale by 2025 | Growth Drivers |
| Automotive Electronics | 1.28 trillion yuan | BMS system and intelligent cockpit for new energy vehicles |
| AI Server | Annual Growth Rate of 39% | Upgrade of Computing Power Chips (such as NVIDIA GPU) |
| Consumer Electronics | 291 million mobile phones | Folding screens drive demand for flexible boards |
Ⅲ. Core challenge: Breaking through low-end lock-in and environmental pressure
1. Difficulty in technological substitution:
In the field of high-end HDI boards and packaging substrates, Japanese and Korean companies (such as Samsung Electric) still hold more than 30% of patents, and the R&D investment intensity of domestic companies (about 4%) is lower than that of international leaders (8% -10%).
2. The cost of environmental compliance has skyrocketed:
The lead-free process transformation has increased the cost of small and medium-sized enterprises by 20%, and 30% of the production capacity in the Pearl River Delta is facing the risk of environmental restrictions.
3. Malignant price competition:
Excessive production capacity of ordinary multi-layer boards and price wars have led to profit margins falling below 5%, forcing companies to transform into specialized products.
Ⅳ. Strategic Opportunity: AI and Green Manufacturing Reshape the Logic of Competition
-AI computing power revolution: By 2025, the global computing power demand will reach 1000EFLOPS, driving a surge in demand for high tier server PCBs, and SysPCB will achieve a 63% increase in net profit.
-Policy dividend release:
The 15th Five Year Plan includes PCB as a strategic industry and sets up special funds to support low-carbon technology research and development.
-Advantages of industrial chain synergy:
China has the world’s most complete electronic manufacturing cluster, which can achieve a rapid response time of 48 hours from copper foil to terminal assembly, and its supply chain efficiency is 30% ahead of Europe and America.
Ⅴ. Future trend: dual wheel drive of intelligence and globalization
1. Technology integration acceleration:
-Embedded component PCB (reduces volume by 30%)
-Mass production of low loss dielectric materials (Df ≤ 0.002)
2. Zero carbon factory becomes standard:
Leading enterprises have introduced photovoltaic power supply and wastewater recycling systems, reducing carbon emission intensity by 40% and meeting the green supply chain requirements of Apple and Samsung.
Action Guide: Three Strategies for Seizing the Future Track
1. Material innovation: Collaborate with upstream to develop domestically produced ABF film, reducing high-frequency substrate costs by 30%;
2. Technological Revolution: Introducing ML driven TDR impedance control system to shorten the development cycle of high multilayer boards by 50%;
3. Green certification: Advance layout of ISO 14064 carbon footprint certification and lock in European automotive electronics orders.
The crust of the global electronics industry is moving – Chinese PCB companies have transformed from cost followers to rule makers with technological resilience (37.92% revenue growth of Shennan Circuit) and manufacturing flexibility (48 hour supply chain in the Pearl River Delta). When the line width of AI server PCBs approaches the physical limit, and when the machine tools in Thai factories sound the buzzing of Chinese brands, the answer to this industrial upgrading has already been written in the genes of Chinese manufacturing.
