Technical Requirements

Substrate: High-Tg FR-4 (Tg ≥ 170°C) - Ensures high-temperature stability and prevents delamination during lamination
Copper Foil Thickness: Signal layer: 1oz; Power/GND layer: 1oz~2oz; High-current paths: ≥2oz - Meets current-carrying and heat dissipation requirements
Surface Finish: ENIG (Immersion Gold) - Offers oxidation resistance and good solderability, suitable for long-term storage
CTI (Comparative Tracking Index): ≥400V (Group I), ≥250V (Group II) - Prevents creepage failure in humid environments
Solder Mask: High CAF-resistant solder mask ink - Suppresses ion migration and improves insulation reliability
