Multilayer Flexible Printed Circuit Board (FPCB) refers to a high-density, ultra-thin, and flexible circuit board with ​three or more layers of conductive pathways integrated into a single component, designed for applications requiring ​complex signal routing, thermal management, and mechanical durability.

 

Key Features & Technical Specifications

  • High-Density Interconnects:
    • Multi-layer stack-up (up to 12 layers) with ​0.03mm trace width allows for complex circuitry in compact devices (e.g., foldable smartphones, wearable sensors)
    • Microvias (0.05mm) and ​blind/buried vias enable 3D routing without compromising signal integrity, ideal for high-speed data transmission (5G, mmWave)
  • Signal Integrity & Performance:
    • Controlled impedance (50Ω–100Ω) ensures minimal signal loss in RF and high-speed applications
    • Dedicated power/ground planes reduce EMI and improve power distribution efficiency, critical for electric vehicles and industrial equipment
  • Thermal Management:
    • Aluminum substrate (thermal conductivity up to ​2.0 W/m·K) and ​phase change materials (PCMs) dissipate heat from high-power components, extending lifespan
  • Design Flexibility & Durability:
    • Supports ​90°–180° bending (minimum radius ​0.5mm) for curved device casings or wearable tech
    • IP67/IP68 certification and ​10,000+ bend cycles ensure reliability in harsh environments
