Main Types of Metal Core PCBs
Based on the choice of metal core material, metal core printed circuit boards (MCPCBs) can be divided into the following three main types:
Aluminum Core PCBs
- Thermal Conductivity: 1-3 W/mK
- Cost-effective solution
- Lightweight construction
Aluminum core MCPCB, featuring lightweight, cost-effectiveness, and excellent thermal conductivity. Widely used in LED lighting, automotive electronics, and power supply applications.
Copper Core PCBs
- Thermal Conductivity: ~400 W/mK
- High-performance
- Durable construction
Copper-core MCPCBs have excellent thermal conductivity and are widely used in high-performance computing (HPC), telecommunications, and industrial equipment.
Mixed Metal Core PCBs
- Balanced performance
- Cost-performance optimized
- Custom configurations
Hybrid metal MCPCB combines the advantages of different metals to achieve a balance between performance and cost to meet specific needs.
