全球与中国汽车雷达高频PCB市场现状及未来发展趋势

Core Viewpoint - The automotive radar high-frequency PCB market is experiencing significant growth driven by the increasing demand for intelligent driving and Advanced Driver Assistance Systems (ADAS), with a shift towards higher frequency radar systems such as 77GHz and 79GHz [3][7]. Industry Development Status - The trend towards higher frequency is evident, with the global market share for 24GHz radar declining as 77GHz/79GHz becomes the mainstream for new vehicles. Mid to high-end models are increasingly equipped with forward and corner radars, leading to a continuous increase in high-frequency PCB usage [3]. - The number of layers in PCBs is increasing, with a notable rise in demand for 6-layer and above PCBs, particularly in long-range forward radars and 4D imaging radars [3]. - Domestic PCB manufacturers in China, such as Huadian Co., Shenzhen South Circuit, and Shengyi Technology, are actively entering the high-frequency radar PCB market, achieving initial breakthroughs in import substitution by supplying to international Tier 1 suppliers [3]. - High-frequency PCB materials are costly, with prices 3 to 5 times higher than FR4, and the complex multi-layer precision processing poses challenges for manufacturing yield and consistency [3]. Development Trends - The evolution towards higher frequency and higher resolution is accelerating, with radar frequencies shifting from 24GHz to 77GHz/79GHz, and the mass production of 4D imaging radars driving the need for PCBs that support higher frequencies and lower losses [4]. - The complexity of PCBs is increasing, with designs evolving from 2-layer and 4-layer to 6-layer and even 8-layer configurations, incorporating RF, power, and control signal layers [4]. - Material diversification is occurring, with an increasing application of materials such as LCP, PTFE, and PPE, while domestic high-frequency substrates are accelerating certification to replace imports [4]. - The high costs associated with materials and processing, along with yield fluctuations, present dual challenges for manufacturers, necessitating a balance between high performance and cost [4]. Market Size and Growth - In 2024, the global automotive radar high-frequency PCB market is projected to reach $285 million, with expectations to grow to $831 million by 2031, reflecting a compound annual growth rate (CAGR) of 16.11% from 2025 to 2031 [7]. - The Chinese market is rapidly evolving, with a projected market size of $58.33 million in 2024, accounting for approximately 20.43% of the global market. By 2031, it is expected to reach $242 million, increasing its global share to 29.18% [7]. - The distribution of automotive radar high-frequency PCBs spans 2 to 10 layers, with 4-layer, 6-layer, and 8-layer products being the most common. The market share for 8-layer products is expected to reach 41.73% in 2024 [8]. - Major global manufacturers include Yahua Electronics, Huadian Co., AT&S, and others, with the top five companies expected to hold a market share of 55.88% in 2024, indicating intensifying competition, especially in the Chinese market [8].
