Mobile Phone FPC

Product Parameters for Mobile Phone FPC

​Parameter ​Specification
​Material Polyimide (PI) or Polyester (PET) for flexibility and durability
​Thickness 0.1mm – 0.3mm (typical for compact designs)
​Conductivity Copper traces with resistance ≤ 0.1Ω/sq (high-current paths)
​Layer Configuration Single-sided, double-sided, or multi-layer (up to 4 layers for complex circuits)
​Pitch & Design 0.15mm-0.4mm pitch for high-density connections; right-angle connectors for compact layouts
​Temperature Range -40°C to +105°C (operational); short-term up to +260°C
​Flex Life Supports thousands of flex cycles (e.g., folding/unfolding)
​Testing Standards Visual inspection (no/shorts), electrical testing (resistance/shorts), thermal cycling

Flexible Printed Circuits (FPC) for Mobile Phones
FPCs are thin, lightweight, and highly customizable circuit boards designed for compact, dynamic smartphone applications. Made from ​polyimide (PI) or ​polyester (PET) substrates, they offer unparalleled flexibility and durability, enabling intricate circuit layouts with ​high-density wiring (as fine as 20μm) and reliable electrical connections

Key Advantages:

  • Space-Saving: Reduce device volume by 70% compared to rigid PCBs, ideal for compact designs like foldable screens and multi-camera setups
  • High-Performance: Support ​up to 3A current for power-hungry components (e.g., fingerprint sensors) and withstand extreme temperatures (-40°C to +105°C)
  • Versatile Applications:
    • Camera Modules: Connect CMOS sensors to the motherboard with precision, ensuring clear images
    • Battery & Antenna Systems: Handle frequent bending and 5G antenna integration
    • Foldable Devices: Enable hundreds of flex cycles without failure

Design Considerations:

  • Layered Configurations: Single/multi-layer options for simple to complex circuits
  • Thermal Management: Optimized for heat dissipation to prevent performance degradation
  • Testing Rigor: Mandatory checks for ​shorts/opens, ​trace integrity, and ​mechanical durability to ensure high yield

Choose FPCs for your mobile devices to achieve ​innovative designs, ​enhanced functionality, and ​cost-effective manufacturing
