The global PCB industry has entered the era of hundreds of billions of dollars, a vast ocean of commerce filled with uncertainties. However, in the strategic choke points of packaging substrates and high-density interconnect (HDI) boards, which determine the industry’s height, the voice of domestic enterprises remains weak. This is not a comprehensive gap in strength, but rather the “Achilles’ heel” that we urgently need to break through in the global industrial chain division of labor. Only by conquering these high-end fields can we break free from the chains of being “large but not strong” and carve out China’s innovative mark on the foundation of the digital age.
The barriers in the high-end PCB field are high, intertwined with technology, capital, and talent, making it a “hard nut to crack.” Packaging substrates, as the “nerve center” of chips, have line widths and spacings refined to the micron level, directly affecting the performance and reliability of integrated circuits, making them the “pinnacle of the electronics industry.” HDI boards are the core carriers for achieving lightweight and multifunctional electronic devices, with technological iterations occurring at a rapid pace. For a long time, these high-end markets have been dominated by Japanese, Korean, and Taiwanese enterprises, while domestic companies have fiercely competed in the relatively lower technical threshold of ordinary multilayer boards. This structural imbalance is like an invisible “technological ceiling,” restricting the ascent of China’s electronic information industry to the top of the value chain.
However, crises give birth to new opportunities, and changes conceal strategic games. The current uncertainty in the international economic and trade environment acts like a Damocles sword, forcing the acceleration of the restructuring of the industrial and supply chains, providing domestic enterprises with a rare “strategic window period.” More critically, the surging power of downstream applications is generating unprecedented market demand. The tide of artificial intelligence computing, the innovation of smart automotive electronic architectures, and the wave of data center construction all crave higher performance and reliability in packaging substrates and HDI boards. This “vast sea” carved out by technological evolution and industrial demand is waiting for domestic ships to set sail into the deep blue.
The way to break the stalemate lies in innovation as the oar and collaboration as the sail, steering towards the deep waters of value creation. Leading domestic enterprises such as Shenzhen Shennan Circuit and Xingsen Technology have begun to lay out high-end technologies, demonstrating their determination and potential to break through. The future journey requires a “three-pronged approach”: first, to continuously increase R&D investment, achieving self-control in key materials, core processes, and advanced equipment, tackling the “hard nuts” of technological innovation; second, to strengthen industrial chain collaboration with domestic chip design and manufacturing companies, building a self-sufficient ecosystem from “chip” to “board” and playing a coordinated game of industry linkage; third, to seize the opportunities of the “dual circulation” development, relying on the vast domestic market advantages, iterating technology and honing competitiveness in serving local customers and rapidly responding to demands, creating a “rapid response team” close to the market.
The hundreds of billions of dollars in the PCB industry have already been laid out, and the competition in high-end fields is a “key battle” concerning the future industrial discourse power. Domestic enterprises can only focus on the high-end with the strategic determination of “grinding a sword for ten years,” aiming for innovation, to carve out a new trajectory belonging to Chinese manufacturing in the vast sea of the global PCB industry, laying a more solid and reliable foundation for China’s and even the world’s digital future. This vast land is bound to achieve great things.
