Metal Core PCBs (MCPCBs)

Where Heat Meets Precision.

As electronic systems push the boundaries of speed, power, and density, managing heat is no longer optional — it’s mission-critical. Insight PCB’s Metal Core PCBs are engineered to dissipate heat efficiently, extending component lifespan, improving performance, and reducing thermal failure risk in demanding environments.

Why Thermal Management Matters

Higher switching speeds, compact form factors, and power-hungry devices have all intensified the thermal demands on modern PCBs. In EVs, renewable energy, and RF systems, thermal buildup can degrade performance or lead to early failure.
Metal Core PCBs (MCPCBs) use a thermally conductive base layer—usually aluminum or copper—to efficiently route heat away from heat-generating components to external heat sinks or ambient surroundings.

Common Metal Core Applications

Material Options & Stackups

Insight PCB supports a range of metal substrates and thermal interface materials (TIMs), including:

  • Aluminum (standard for LED and moderate power)
  • Copper (for superior conductivity and heat spread)
  • Hybrid stackups with embedded thermal vias
  • Insulating dielectrics with high thermal conductivity and electrical isolation
  • Single- and double-sided MCPCBs with plated through-holes

We also support UL-approved metal core designs with copper weights up to 6 oz, ensuring mechanical and thermal robustness even in high-current designs.

Built for Harsh Conditions

MCPCBs are ideal for use in:

  • High-vibration environments
  • High-temperature industrial settings
  • Compact designs with poor airflow
  • Systems requiring stable thermal cycling over time

At Insight PCB, we help you design smarter, cooler systems by pairing the right materials, stackup, and layout strategy to meet your thermal and electrical needs.
