IPC Class2 Quick Turn Metal Core PCB Board for LED Street Lights

Metal core PCBs utilize specialized substrates categorized by thermal and mechanical properties:

• Aluminum cores: 1-3 W/mK thermal conductivity, ideal for LED lighting and automotive power systems
• Copper cores: Superior thermal transfer (380-400 W/mK) for RF amplifiers and high-power converters
• Iron alloy cores: Provide unique magnetic permeability for motor controllers and EMC-sensitive environments
• Composite cores: Aluminum-copper hybrids offer balanced thermal-mechanical performance for aerospace applications
• Ceramic cores: Serve laser diodes and satellite systems with 170-230 W/mK conductivity

Production involves 18 critical stages with rigorous quality control:

• CNC-milled metal cores with ≤0.1mm/m² flatness tolerance
• Surface preparation including alkaline washing and anodization
• Dielectric lamination with thermally conductive polymers
• Circuit fabrication supporting copper weights from 1oz to 10oz
• Laser direct imaging enabling 0.15mm trace/space tolerances
• Thermal management features including conductive epoxy via fills

• Thermal performance: 1.0mm aluminum cores achieve 1.8°C/W resistance
• Certifications: IATF 16949 (automotive), ISO 13485 (medical), UL 94 V-0
• Prototype lead times: 7 days for 5-panel batches
• Volume production: Minimum 1m² shipping in 15 days
