4-Layer Flexible PCB High-Heat Ceramic FPC for Aerospace

Product Overview:

Engineered for high-reliability environments, this 4-layer Flexible PCB (FPC) combines advanced Ceramic filling technology with a robust Immersion Gold (ENIG) finish. Designed to meet 94V0 flame retardant standards, it offers exceptional thermal management and signal integrity in ultra-thin, bendable configurations. Whether for aerospace sensors, high-end medical probes, or compact telecommunications hardware, this FPC ensures durable performance under extreme temperatures while maintaining a space-saving footprint for complex 3D assemblies.

Key Selling Points:

• High Thermal Stability: Ceramic-enhanced base for superior heat dissipation.

• ENIG Surface Finish: Excellent solderability and oxidation resistance.

• UL 94V-0 Certified: Guaranteed flame retardancy for critical safety applications.

Engineering Support: DFM (Design for Manufacturing) check before production.

Testing: Flying Probe Test, Fixture Test, Impedance Control Test, Thermal Stress Test.
