  Advantages of Metal Core Printed Circuit Boards (MCPCB)


Advantages of Metal Core Printed Circuit Boards

MCPCBs can be advantageous to use for their ability to integrate a dielectric polymer layer with a high thermal conductivity for a lower thermal resistance.


1.heat dissipation

Some LEDs dissipate between 2-5W of heat and failures occur when the heat from a LED is not properly removed; a LED’s light output is reduced as well as degradation when the heat remains stagnant in the LED package. The purpose of a MCPCB is to efficiently remove the heat from all topical IC’s (not just LEDs). The aluminum base and thermally conductive dielectric layer act as bridges between the IC’s and heat sink. One single heat sink is mounted directly to the aluminum base eliminating the need for multiple heat sinks on top of the surface mounted components.


2. thermal expansion

Thermal expansion and contraction is the common nature of the substance, different CTE is different in thermal expansion. As its own characterics, aluminum and copper have unique advance than normal FR4, thermal conductivity can be 0.8~3.0 W/c.K.


3. dimensional stability

It is clear that the size of the metal-based printed circuit board more stable than insulating materials. The size change of 2.5 ~ 3.0% when Aluminum PCB and aluminum sandwich panels was heated from 30 ℃ to 140 ~ 150 ℃.


Metal core PCBs transfer heat 8 to 9 times faster than FR4 PCBs. MCPCB laminates dissipate heat, keeping heat generating components cooler which results in increased performance and life.

Applications that generate a large amount of heat often cannot be adequately cooled using just traditional fans. Conductive cooling through metal core PCBs are an ideal production option.

MCPCBs are most widely found in LED technologies, as they reduce the number of LEDs required to produce a specific illumination. Light emitting diodes release a great amount of heat in applications such as:

  • Back light unit applications
  • Street safety applications (streetlights, lighting, etc.)
  • General lighting applications
  • System automotive LED applications
  • Power converters:  telecom, industrial, high voltage regulator, power supplies
  • Hybrid/electric motor control applications
  • Photovoltaic


Using a metal core PCB in these LED products and applications help to greatly reduce the heat emitted.

Other applications that are ideal for MCPCB integration are solar panels and motion control applications. We can also combine metal core with our HDI PCB technology.
