    Core Performance Highlights​

    ◈.Structural Support​
    ● Rigid structure resists deformation from component weight/assembly stress​
    ● Moderate vibration resistance (suitable for industrial/automotive via fixed installation)​
    ● Longer service life than flexible PCBs in static scenarios​
    ◈. Electrical Transmission​
    ● Stable dielectric properties (FR-4: 4.2-4.8) for high-speed signal integrity​
    ● Precision impedance control (±10%) for high-frequency/RF circuits​
    ● 1-40 layers with blind/buried vias/HDI for high-density interconnection​
    ◈. Thermal Management​
    ● Operating temp: -50℃ to +150℃ (Standard FR-4); 170-180℃ (High Tg)​
    ● Thermal vias/conductive materials for efficient heat dissipation​
    ● Low CTE (14-18 ppm/℃) to prevent delamination/cracking​
    ◈. Mass Production Adaptability​
    ● Supports 1-100,000+ pcs orders with cost advantages​
    ● Fast delivery: 3-5 days (prototypes), 5-15 days (mass production)​
    ● Customizable (board thickness, copper thickness, surface finish, etc.)​

    Key Product Advantages​

    ◈ Stable & Reliable: Low failure rate for long-term continuous use (rigid structure + mature processes)​
    ◈ Balanced Performance: Mechanical strength, electrical performance, thermal stability in one​
    ◈ Cost-Effective: High production efficiency + flexible material selection​
    ◈ Flexible Design: Supports multilayer, high-density, impedance-controlled designs​
    ◈ Controllable Quality: Full-process inspection (AOI, Flying Probe) + international standards compliance​

    Key Applications

    Our Rigid PCBs are widely used in:
    ◈ Consumer Electronics (Smartphones, Laptops, TVs, Wearables)
    ◈ Industrial Automation (Controllers, Sensors, Power Supplies)
    ◈ Automotive Electronics (Infotainment Systems, ADAS Modules, Engine Controls)
    ◈ Medical Devices (Diagnostic Equipment, Portable Healthcare Tools)
    ◈ Telecommunications (Routers, Switches, Base Stations)
    ◈ Aerospace & Defense (Avionics, Military Communication Devices)
