Metal Core PCB Solutions
Aluminum and copper base PCBs for high-power LED, thermal management, and power electronics. Superior heat dissipation with precise manufacturing.
What is a Metal Core PCB?
A Metal Core PCB (MCPCB) uses a metal base — typically aluminum or copper — as the core substrate for superior heat dissipation. Unlike standard FR-4 boards, MCPCBs channel heat away from power-hungry components, improving performance and longevity.
Aluminum Core
1W/mK Thermal Conductivity
Cost-effective and widely used in LED lighting and general power applications. Aluminum base provides efficient heat spreading at a competitive price point.
Copper Core
380W/mK Thermal Conductivity
Superior thermal performance for high-power-density applications. Copper base delivers unmatched heat dissipation for demanding designs.
Key Benefits
Superior Heat Dissipation
The metal base layer rapidly conducts heat away from components, reducing junction temperatures and extending product lifespan significantly.
Higher Current Capacity
Thicker copper layers on metal core substrates handle higher current loads without overheating, ideal for power electronics and LED arrays.
Enhanced Mechanical Strength
The metal base provides rigidity and dimensional stability, reducing warpage and improving reliability in high-vibration environments.
Applications
Metal core PCBs excel in thermally demanding environments.
LED Lighting Systems
High-power LED modules, street lighting, and automotive headlamps that require efficient thermal management.
Power Electronics
Motor drives, power supplies, inverters, and converters that generate significant heat during operation.
Automotive & Aerospace
Engine control units, LED taillights, and avionics that demand thermal reliability under extreme conditions.
