In 2025, driven by the expansion of data centers, the increasing adoption of smart vehicles, and the widespread use of wearable devices, wire-to-board and board-to-board connectors will accelerate their upgrade toward "high-speed, miniaturization, and greenization," with the industry landscape continuing to reshape

Technology: Breakthroughs in Three Major Directions

• Board-to-board: Adapting to 112Gb/s transmission rates has become mainstream. Products with 0.35mm spacing can save 25% of PCB space, while high-density models achieve a linear density of 84 differential pairs per inch, meeting the integration demands of high-end equipment

• Line-to-Board: Products with spacing of 0.5mm and below account for over 59% of the market share, with 0.2mm spacing solutions widely used in small consumer electronics. The terminal coplanarity must be controlled within ±2μm. Automotive products achieve IP67 protection, 150°C temperature resistance, and 10Gbps transmission, passing automotive-grade certification to become a standard configuration

• Greening: The penetration rate of eco-friendly materials has reached 60%, the mandatory usage of recycled plastics will be increased to 20%, lead-free soldering coverage exceeds 90%, and the carbon footprint is reduced by over 40% compared to traditional products

Application: Leading in Emerging Fields

• Data Centers: The usage of high-speed board-to-board connectors in servers and storage systems increased by over 30% year-on-year, meeting the demand for 112GB/s speeds

• Smart Vehicles: The market size of automotive wire-to-board connectors reached .13 billion in 2024, with high-voltage connectors accounting for 38.6% of the total. The localization rate of connectors related to new energy vehicles has reached 58%

• Medical/Industrial: Suitable for harsh environments such as disinfection settings and temperature ranges from -40°C to +85°C, driving demand for customized, high-reliability products

Structure: Local Acceleration of Replacement

China accounts for 46.5% of the global connector production capacity, with domestic companies achieving significant technological breakthroughs in automotive and industrial applications. Production lines for connectors with spacing below 0.35mm are in high demand. Experts predict that after the implementation of PCIe Gen 7 in 2026, connectors will upgrade to 224Gb/s speeds and sub-0.3mm spacing, giving enterprises with superior performance, environmental, and cost advantages a stronger competitive edge
