What is MCPCB(Metal Core PCB)?

Metal core PCBs (MCPCBs) are PCBs that have a metal core, usually made of aluminum and copper alloy, instead of the traditional FR4 PCB(Fiberglass Reinforced Epoxy). The metal core PCB has better thermal conductivity and more efficient heat dissipation. As a result, aluminum PCBs is ideal for high-power applications such as swimming pool LED lighting, power electronics, and LED car lighting and hotel lighting.

Types of Metal Core PCBs

Single-layer metal core PCB
Single-layer metal core PCB is the simplest MCPCB, which is only composed of a copper layer as the circuit trace, a thermal conductivity layer and a metal base (normally is aluminum or copper).

Two-layer metal core PCB
Two-layer MCPCB means it has two layers circuit layer on this board. But different with double-sided MCPCB, both two layers copper traces are on the same side and metal base located on the bottom side of circuit board.

Double-sided Metal core PCB
Two-layer MCPCB means it has two layers circuit layer on this board. But different with double-sided MCPCB, both two layers copper traces are on the same side and metal base located on the bottom side of circuit board.

Multilayer Metal Core PCB

Compared to standard FR4 PCBs, the construction of multilayer MCPCBs requires advanced technology and expertise in laminating multiple layers together with a metal core. As a result, the cost of multilayer MCPCBs is significantly higher than that of 2-layer or double-sided MCPCBs.

metal core pcb application

Copper core PCBs are suitable for applications with large temperature differences between high and low temperatures, those requiring high thermal dissipation, and high-frequency circuits.


The applications of metal core pcbinclude LED lighting, automotive electronic parts, power modules, high-frequency military communication/radar/detectors, power supplies, etc.
We classify the applications of metal core pcbbelow.


1.Automotive: vehicle headlights, ignitors, and power controllers.
2.LED lighting: fluorescent lamps, street lamps, downlights, wall washers, mining lamps, stage lights, and ship lights.
3.Power modules: converters, solid relays, and rectifier bridges.
4.Power supplies: switching regulators and DC/AC converters.
5.Audio equipment: I/O amplifiers, balanced amplifiers, audio amplifiers, preamplifiers, and power amplifiers.
6.Communication electronics: high-frequency amplifiers, filters, and transmitters.
7.Office and home appliances: motor drivers in fans, range hoods, washing machines, and whirlpools.
8.Computers: CPU boards, floppy disk drives, and power supply devices.

2-4 layer metal core pcb Design

Because the copper base is thick, the minimum drill bits for copper core PCB must be 0.4mm.

The PCB circuit thickness determines the trace width/space. The larger the copper thickness, the larger the trace width/space.

As most copper-core PCBs are high-current PCB boards, you can read high-current PCB design tips that shine a light on copper-core PCB design.
