Precision 6-Layer HDI PCB | Ultra-Compact Hearing Aid Design

Product Overview:

Our 6-layer HDI PCBs represent the pinnacle of miniaturization for the modern hearing aid industry. By integrating advanced multi-layer laser micro-via technology, we enable high-density routing of complex DSP circuits in a footprint smaller than a fingernail. These boards are engineered for exceptional signal-to-noise ratios, ensuring crystal-clear audio processing and low power consumption. With superior thermal stability and moisture resistance, our HDI solutions provide the reliable foundation required for high-end medical wearables and invisible-in-canal (IIC) devices.

Key Selling Points:

• Extreme Scale: 6-layer HDI structure for invisible wearable tech.

• Audio Clarity: Low-noise routing for high-fidelity DSP processing.

• Medical Reliability: 100% AOI & E-test for life-critical performance.

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

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