If your project is going to be designed in field of high power electronics, it is vital to keep the temperature low—and that’s where Metal Core PCBs shine. Unlike the usual FR4 PCBs, these innovative boards feature a metal base, like aluminum or copper, which effectively pulls heat away from the components. This makes them perfect for tough applications such as LED lighting, automotive electronics, and power supplies. In this blog, we’ll take a closer look at what sets Metal Core PCBs apart, how they’re constructed, and why SMTFAB is your go-to partner for dependable, high-performance thermal solutions.
What is Metal Core PCB?
When your circuit board handles high power, managing heat becomes a serious concern. Metal core PCB helps solve this. Instead of using the typical FR4 material, it uses a metal base—often aluminum or copper. This metal layer spreads heat away from sensitive components. It moves it toward the metal core or heatsink, keeping your board stable during operation.
These PCBs are used in LEDs, power supplies, and automotive systems—anywhere heat builds up quickly. In multilayer designs, the metal sits at the center. In a 12-layer metal core PCB, you’ll find six layers on each side of the metal core. This even structure helps control thermal stress.
You might also hear them called thermal-clad boards, but metal core PCB is the most common term. These boards include a solder mask, copper, a dielectric layer, and the core itself. That metal core acts as a heat spreader. If your design needs solid thermal control without relying on fans, an MCPCB is a smart choice. It handles heat at the source, improving reliability and performance without complicating your setup.
Materials and Thickness of Metal Core PCB
When it comes to Metal Core PCBs, the material and thickness of the core really matter. Most of the time, you’ll see aluminum used. It’s affordable, easy to work with, and handles heat well. Copper is another option. It’s great for thermal performance but costs more. Some boards use special alloys too, but those are rare. Materials like brass or steel? Not ideal. They’re hard to cut and may react with chemicals used during manufacturing.
The metal plate inside the PCB spreads heat and adds strength. When it comes to thickness, you’ll typically find it ranging from 30 mils to 125 mils. Some of the most common sizes you’ll encounter are 1mm, 1.5mm, and 3.2mm. These sizes work well with mounting hardware and keep the board flat.
The copper foil on top can range from 1 to 10 ounces, though 1oz to 2oz is most common. It’s enough for most thermal needs without adding extra weight or cost. The metal layer—usually left uncovered—also provides structure.
In a typical MCPCB, you’ll find layers like copper (35µm), dielectric (100µm), and the metal core itself, often aluminum, at about 1.5mm thick. These layers work together to manage heat and protect your components.
Metal Core PCB Structure
Solder Mask Layer: This is the top layer, providing protection for the board.
Circuit Layer: Located just beneath the solder mask, this layer contains the electrical traces and connections.
Copper Layer: The copper layer, typically ranging from 1oz to 6oz, is crucial for conducting electricity. 1oz to 2oz thickness is sufficient.
Dielectric Layer: Nestled between the copper and the metal core, this layer acts as insulation, stopping electrical shorts.
Metal Core Layer: The final and most crucial layer, the metal core (often aluminum or copper), acts as the heat spreader. It draws heat away from sensitive components to prevent overheating.
Metal Core PCB Types
Single Layer Metal Core PCB
This type consists of just one trace layer on one side of the metal core. It is commonly used in simpler applications where minimal heat dissipation and space are required. Despite its simplicity, it still offers good thermal management for low to moderate power applications.
COB (Chip-on-Board) Metal Core PCB
In this configuration, only one trace layer is used. The chip is directly mounted on the board, which is useful for applications like LED lights or other devices that require compact, efficient heat management. The direct mounting reduces the size and improves the thermal conductivity of the setup.
Double Layer Metal Core PCB
A double-layer MCPCB has two trace layers, but they are placed on the same side of the metal core. This configuration provides more room for circuitry and improves heat dissipation while maintaining a relatively simple design.
Double-Sided Metal Core PCB
With trace layers on both sides of the metal core, double-sided MCPCBs can accommodate more components in the same space. This type is beneficial when high component density is required while still ensuring effective heat management.
Multi-layer Metal Core PCB
This type features more than two trace layers distributed across both sides of the metal core. Multi-layer MCPCBs are designed for high-performance applications that require complex circuits, high power handling, and efficient heat dissipation. They are ideal for advanced technology like power supplies, automotive electronics, and LED systems.
Metal Core PCB Advantages
When working with high-power or heat-sensitive electronics, managing temperature is critical. This is where the advantages of MCPCB—or Metal Core PCBs—become especially valuable. These boards transfer heat much faster than traditional FR4 boards.
Aluminum is the most widely used metal in these designs. It’s lightweight, durable, and environmentally friendly. The metal core acts as a heat spreader, drawing thermal energy away from critical parts.
In terms of mechanical strength, MCPCBs also excel. The rigid metal base reduces vibration, which keeps components more secure. The structure remains dimensionally stable under temperature changes.
Aluminum-based PCBs also weigh less than ceramic alternatives while maintaining better conductivity and longer service life. They’re commonly used in LED lighting, power modules, and automotive electronics where heat and durability are major concerns.

Instead of using the typical FR4 material, it uses a metal base—often aluminum or copper. This metal layer spreads heat away from sensitive components. It moves it toward the metal core or heatsink, keeping your board stable during operation.
These PCBs are used in LEDs, power supplies, and automotive systems—anywhere heat builds up quickly. In multilayer designs, the metal sits at the center. In a 12-layer metal core PCB, you’ll find six layers on each side of the metal core. This even structure helps control thermal stress.
You might also hear them called thermal-clad boards, but metal core PCB is the most common term. These boards include a solder mask, copper, a dielectric layer, and the core itself. That metal core acts as a heat spreader. If your design needs solid thermal control without relying on fans, an MCPCB is a smart choice. It handles heat at the source, improving reliability and performance without complicating your setup.
Materials and Thickness of Metal Core PCB
When it comes to Metal Core PCBs, the material and thickness of the core really matter. Most of the time, you’ll see aluminum used. It’s affordable, easy to work with, and handles heat well. Copper is another option. It’s great for thermal performance but costs more. Some boards use special alloys too, but those are rare. Materials like brass or steel? Not ideal. They’re hard to cut and may react with chemicals used during manufacturing.
The metal plate inside the PCB spreads heat and adds strength. When it comes to thickness, you’ll typically find it ranging from 30 mils to 125 mils. Some of the most common sizes you’ll encounter are 1mm, 1.5mm, and 3.2mm. These sizes work well with mounting hardware and keep the board flat.
The copper foil on top can range from 1 to 10 ounces, though 1oz to 2oz is most common. It’s enough for most thermal needs without adding extra weight or cost. The metal layer—usually left uncovered—also provides structure.
In a typical MCPCB, you’ll find layers like copper (35µm), dielectric (100µm), and the metal core itself, often aluminum, at about 1.5mm thick. These layers work together to manage heat and protect your components.

Metal Core PCB Advantages
When working with high-power or heat-sensitive electronics, managing temperature is critical. This is where the advantages of MCPCB—or Metal Core PCBs—become especially valuable. These boards transfer heat much faster than traditional FR4 boards.
Aluminum is the most widely used metal in these designs. It’s lightweight, durable, and environmentally friendly. The metal core acts as a heat spreader, drawing thermal energy away from critical parts.
In terms of mechanical strength, MCPCBs also excel. The rigid metal base reduces vibration, which keeps components more secure. The structure remains dimensionally stable under temperature changes.
Aluminum-based PCBs also weigh less than ceramic alternatives while maintaining better conductivity and longer service life. They’re commonly used in LED lighting, power modules, and automotive electronics where heat and durability are major concerns.

Frequently Asked Questions
Traditional FR4 PCBs use a fiberglass and epoxy resin core, which is less effective in managing heat. MCPCBs stand out for their impressive mechanical strength and durability, especially in larger formats where their rigidity plays a key role in maintaining structural integrity.
While they do come with a higher price tag and are a bit heavier, MCPCBs can often do away with the need for bulky heat sinks, which makes them a more space-efficient option in certain designs. On the other hand, FR4 PCBs offer greater flexibility in design and layer stacking, making them a great fit for complex multilayer layouts.
When it comes to thermal performance, MCPCBs really shine, enhancing reliability and prolonging the life of components. With thermal conductivities between 1.0 and 3.0 W/mK, they effectively lower thermal resistance and help keep overheating at bay. Although MCPCBs might introduce some design challenges in high-frequency circuits, they can be a cost-effective choice in situations where managing heat is crucial. Ultimately, the decision between MCPCB and FR4 hinges on the specific thermal, mechanical, and design requirements of your application.
Metal Core PCBs (MCPCBs) are not universally applicable across all electronic applications. Their real strength comes from their ability to handle heat and withstand mechanical stress, making them perfect for certain high-power situations.
MCPCBs shine in applications like LED lighting, power supplies, automotive electronics, and other scenarios where effective thermal conductivity and resistance to vibrations are crucial. They play a key role in prolonging the life of components by efficiently dissipating excess heat and enduring tough mechanical conditions.
That said, for low-power or simpler electronic designs, the extra cost and complexity of MCPCBs might not be worth it. In situations where thermal loads are light or where space allows for traditional heat sinks, standard FR4 PCBs can be a more budget-friendly and versatile choice.
Additionally, MCPCBs need more specialized manufacturing processes, which can affect lead times and design options. While they are a great fit for demanding thermal and mechanical requirements, they aren’t necessarily the best solution for every situation.
The thermal conductivity of a Metal Core PCB (MCPCB) usually ranges from 1 to 9 W/mK, and this can vary based on the specific core material and design used. This value far exceeds that of standard FR4 PCBs, which generally offer only around 0.3 W/mK. The substantial difference highlights the superior thermal management capability of MCPCBs. These boards are constructed using a metal core to efficiently channel heat away from high-power components.
