PCB is the key support and connection cornerstone of electronic components. At present, servers and data centers have become the new driving force for the overall growth of the PCB industry.
In recent years, due to the gradual transfer of global PCB manufacturing capacity to Chinese mainland, the PCB market in mainland China has shown a trend of rapid development. The agency estimates that the global PCB output value is expected to reach $98.4 billion by 2027.

The upstream link of PCB includes basic raw materials, such as copper clad laminates, prepregs, copper balls, copper foils, etc., and the downstream applications mainly include communications, consumer electronics, automotive electronics and other fields.
In terms of the composition of operating costs, direct materials account for the highest proportion. Among them, copper clad laminate (CCL) plays a prominent role in the production of printed circuit boards, mainly by coating or impregnating polymer resin onto glass fiber cloth, and then hot pressing with copper foil.

Copper clad laminate is a plate formed by impregnating the reinforcing material with resin glue, covering copper foil on one or both sides, and through the hot pressing process, which is an indispensable core material for the manufacture of printed circuit boards.
The main function of copper clad laminate is to realize the conduction, insulation and support of printed circuit boards.
In terms of the classification of copper clad laminates, it mainly includes mechanical rigidity, the type and structure of insulating materials, the thickness of the plate, and the types of reinforcing materials.

The global market share of special types of rigid copper clad laminates is mainly concentrated in the hands of a few leading global companies.
The special type of rigid copper clad laminate has high technical difficulty and has formed a high technical barrier. The top 10 companies occupy about 85% of the market share, which is higher than the ordinary copper clad laminate industry.
According to Prismark data, among the top 23 rigid copper clad laminate manufacturers in global sales in 2022, mainland domestic enterprises occupy 7 seats.
However, in the field of special rigid copper clad laminates, the market share of mainland enterprises is relatively low. Among the top 13 special rigid copper clad laminate manufacturers in the world, only Shengyi Technology is on the list in China.
Market share of global rigid copper clad laminate enterprises in 2022:
In recent years, the rapid development of AI has led to a global server shortage, and the demand for PCB products has increased sharply, driving the demand for high-speed copper clad laminates.
High-end CCL laminates can be subdivided into high-speed, high-frequency CCL laminates and substrates designed for high-density interconnection technology.
At present, the mainland mainly produces low-value-added ordinary copper clad laminates, and still relies heavily on imports in terms of high-end copper clad laminates.
The domestic manufacturers in the field of high-speed copper clad laminates mainly include Shengyi Technology, Nanya New Materials, and Huazheng New Materials. Xinbao New Material Technology, Nantong Xingchen Synthetic Materials, Shengquan Group, Dongcai Technology, etc. have also realized the independent research and development and production of key resin materials such as polyphenylene ether and polytetrafluoroethylene, and have been stably supplied.
In addition, domestic enterprises are also actively laying out the server PCB market, and companies such as Shanghai Electric Co., Ltd., Shenghong Technology, Shennan Circuit, Shengyi Electronics, Guanghe Technology, and Aoshikang have accelerated their layout. #PCB ##汽车##人工智能##服务器#
Under the upsurge of automobile electrification and intelligence, automotive PCB is also expected to usher in the opportunity of rising volume and price. The top three companies in the global automotive PCB market are all Japanese-funded companies, namely CMK, Mektron, and Meiko. A number of domestic enterprises have actively entered the automotive PCB field, mainly including Dongshan Precision, Kinwong Electronics, Shanghai Electric Co., Ltd., Shiyun Circuit and Shengyi Technology.
