Copper Base PCB Vs Aluminum PCB Vs Ceramic PCB

  • Copper base PCBs, aluminum PCBs, and ceramic PCBs are three types of PCBs used for power devices. Below is a comparison among them.
  • Copper base PCBs: the thermal dissipation rate reaches 400W/mK. The thermal dissipation f regular copper-based PCBs is 1W/mK to 8W/mK.1 to 8 layers are available. The price is higher than aluminum PCBs and lower than ceramic PCBs.
  • Aluminum PCBs: the thermal dissipation is 1W/mK to 9W/mK. 1 to 4 layers are available. The price is only $39/㎡ for bulky production.
  • Ceramic PCBs: the thermal dissipation of aluminum nitride PCB is 180W/mK; the thermal dissipation of alumina PCB is 20W/mK. 1 and 2 layers are available. Ceramic PCBs have the best thermal dissipation. The price is higher than copper base PCBs and aluminum PCBs.
  • PCBONLINE manufactures and assembles all the above PCBs. All the above PCBs can be single/double-sided and high-density. And we can customize the thermal dissipation of the PCB for your project. Please feel free to contact PCBONLINE by email at

Copper Base PCB Composition and Fabrication

copper PCB fabricated from hybrid lamination
Copper base PCB, also known as copper core PCB and copper substrate PCB, is a metal core PCB (MCPCB) that uses copper as the PCB substrate material.
A copper base PCB is mainly composed of a copper substrate, polymer layers, and copper circuit layers.
Copper PCB substrate: the copper substrate is the mechanical support to the copper base PCB and conducts heat.
Polymer layers: polymer composed of aluminum oxide and silicon powder filled with epoxy resin. Polymer layers are between the copper substrate and circuit layers. They insulate different copper layers. The thermal resistance is small.
Copper circuit layers: circuit layers of copper base PCBs require to withstand large currents. The copper thickness usually ranges from 35μm to 350μm.
The fabrication of regular copper base PCBs is similar to aluminum PCB fabrication. When we generate circuits on the copper substrate core, we laminate alternating layers of polymer and copper on the core and generate circuits on the copper layers.
PCBONLINE can achieve hybrid lamination of copper base PCB with other materials. For example, the above COB LED light PCB was a ceramic PCB embedded in a copper base PCB.

Advantages of Copper Base PCBs

  • Copper base PCBs are used for high-power devices because of these advantages:
  • High thermal conductivity: the thermal dissipation rate of copper base PCBs is dozens of times larger than that of aluminum PCBs.
  • Cost-effectiveness: the price of copper base PCBs are much lower than ceramic PCBs.
  • ● Copper base PCBs can be designed to be HDI, hybrid-laminated, and circuit layers up to 8.
