Ultra-Miniature 4-Layer HDI PCB: Advanced Hearing Aid Solution
Product Overview:
Our 4-layer HDI PCBs are meticulously engineered for the ultra-miniature requirements of modern hearing aids and wearable medical devices. Utilizing high-precision laser micro-via technology and advanced stack-ups, we enable complex digital signal processing (DSP) in an incredibly small footprint. These boards feature superior signal integrity and low-noise performance, essential for crystal-clear audio amplification. Designed for daily wear, our PCBs offer exceptional resistance to moisture and thermal stress, providing the reliable core needed for life-enhancing medical technology.
Key Selling Points:
• Extreme Density: Precision micro-vias for ultra-compact hearing aids.
• Low Noise: Optimized signal integrity for clear audio processing.
• Medical Grade: High-reliability materials with superior corrosion resistance.
Engineering Support: DFM (Design for Manufacturing) check before production.
Testing: Flying Probe Test, Fixture Test, Impedance Control Test, Thermal Stress Test.
