2025 4-Layer PCB Solution for Dental Electric Chairs - Micron-Level Control · Cost-Efficiency Excellence
Based on the ISO 13485:2025-certified PCB Manufacturing and Assembly system, we achieve 16-axis coordinated positioning through a 4-layer high-precision impedance-controlled board, overcoming the triple challenges of spatial constraints, electromagnetic compatibility, and sterilization compatibility:
✅ Innovative 4-Layer Board Design
Compact Motion Control
- 0.08mm repeatability accuracy: Utilizes 2oz thick copper power layers (current-carrying capacity ↑40%) + impedance-controlled signal layers (error <1%, compliant with ISO 22196:2025).
- Sterilization Tolerance: TG170 high-glass-fiber substrate, withstanding >300 cycles of hydrogen peroxide plasma sterilization (EN 556-1 certified).
✅ Cost-Optimized Performance Validation
