Technical Features
Material Selection & Characteristics
- High-Frequency Performance: Low dielectric constant materials reduce signal transmission loss
- High Reliability: Withstands complex outdoor environments including temperature/humidity changes and vibration
- Signal Integrity: High-purity copper foil with low surface roughness
Manufacturing Process
- High Precision: Laser Direct Imaging (LDI) technology for pattern transfer
- Layer-to-Layer Registration: CNC and laser drilling for microvias (0.05mm-0.15mm)
- Quality Control: Strict temperature and pressure profiles during lamination
Electrical Performance
- Impedance Control: ±5% or ±10% tolerance using TDR verification
- Signal Integrity: Guard routing and ground plane optimization
- EMC Compliance: Metal shielding for RF sections
Reliability Assurance
- Thermal Management: Thermal via arrays and copper heat-spreading channels
- Environmental Protection: Conformal coating for moisture, salt fog, and fungus protection
- Long-term Stability: IPC-6012 and IPC-6018 compliance
