Speaker Double-Side Flexible Printed Circuit Board refers to a high-density, ultra-thin, and flexible circuit board designed for ​audio signal transmission, loudspeaker drivers, and dynamic noise cancellation systems in consumer electronics, automotive audio, and IoT-enabled devices.

Key Features & Technical Specifications

  • Ultra-Thin & Flexible Design:
    • 0.1mm thickness reduces device bulk by up to ​40% compared to rigid PCBs, ideal for slim wireless speakers, earbuds, or automotive headrest speakers.
    • Supports ​10,000+ bend cycles (minimum bend radius: ​0.5mm) for dynamic designs in foldable speakers, wearable audio devices, or curved automotive panels.
  • High-Density Interconnects:
    • Dual-layer routing with ​0.03mm/1mil minimum trace width enables multi-channel audio processing (e.g., stereo, 5.1-channel surround sound).
    • Microvias (0.05mm/2mil) andblind/buried vias allow compact layouts for high-power amplifiers, MEMS microphones, or wireless charging coils.
  • Signal Integrity & Audio Quality:
    • Controlled impedance (100Ω–1GHz) ensures minimal signal loss for high-fidelity audio transmission (e.g., Hi-Res certification).
    • EMI shielding and ​crosstalk suppression eliminate noise interference in Bluetooth speakers or public address systems.
  • Power Efficiency & Thermal Management:
    • Optimized heat dissipation for high-power Class D amplifiers, reducing thermal throttling in portable speakers.
    • Voltage tolerance up to 24V supports automotive or industrial-grade audio systems.
  • Durability & Environmental Resistance:
    • Conformal coating and ​IP67/IP68 certification protect against moisture, dust, and temperature extremes (-40°C to 125°C).
    • RoHS/REACH compliance and ​halogen-free materials ensure eco-friendly production and global market access.
  • Advanced Manufacturing:
    • laser drilling and ​AOI (Automated Optical Inspection) guarantee precision in via alignment and defect-free production.
    • IPC-6012 Class 2/3 certification ensures trace width accuracy (±2μm) and solderability for mass production.
