Aluminum PCBs gives excellent thermal management and durability. Specifically crafted for high-power electronics, these boards do a fantastic job of dissipating heat, which helps prevent overheating and boosts reliability. Thanks to their combination of being lightweight and durable, aluminum PCBs have become a go-to choice in fields such as LED lighting, power supplies, and automotive electronics. In this guide, we’ll explore the key aspects of aluminum PCB design, touching on everything from choosing the right materials to the manufacturing processes and common applications.
What is Aluminum PCB?
One of the most common metal core PCBs. It looks like a standard PCB, but instead of a fiberglass base, it has an aluminum core. This metal base pulls heat away from components fast, keeping them cool and improving performance. That’s why aluminum PCBs work well in high-power electronics. You’ll find them in LED lighting, power supplies, and even automotive systems.
Like other circuit boards, aluminum PCBs have copper layers, a solder mask, and a silkscreen. The aluminum core helps with strength and durability, making the board more resistant to bending. It also improves electromagnetic shielding, which protects signals from interference. Even cell phone cameras rely on aluminum PCBs for better stability.
These boards have been around since the 1970s, first used in power circuits. Today, they are more popular than ever, especially in LED technology. Their ability to handle heat makes them a top choice for modern electronics.
Performance of Aluminum PCB
Aluminum PCBs stand out for their excellent heat management. Regular PCB materials like FR4 and CEM3 struggle with heat dissipation. If heat builds up, electronic components can overheat and fail. Aluminum PCBs prevent this by pulling heat away from components, keeping everything cooler and more reliable.
They also handle thermal expansion better. Different materials on a PCB expand and contract at different rates when heated. This can cause stress on components and weaken connections. Aluminum PCBs reduce this problem, improving the durability of the whole system. This is especially useful in SMT (surface mount technology) applications, where precision is key.
Dimensional stability is another advantage. When exposed to heat, aluminum PCBs change size far less than standard insulating materials. From 30°C to 150°C, their expansion is minimal—only about 2.5% to 3%.
Beyond that, aluminum PCBs offer shielding against interference, replace fragile ceramic boards, and improve heat resistance. They also help lower production costs by reducing the need for extra cooling solutions.
Structure and Feature of Aluminum PCB
Circuit Copper Layer
This layer consists of electrolytic copper foil, etched to form circuits. It allows component connections and assembly. Compared to FR4, aluminum PCBs handle higher currents at the same thickness and line width. The copper layer is thicker than standard CCLs, ranging from 1oz to 10oz, increasing current-carrying capacity.
Dielectric Insulation Layer
This thermally conductive layer bonds layers together, provides insulation, and helps with heat dissipation. It is 50μm to 200μm thick with low thermal resistance, ensuring efficient heat transfer. A higher thermal conductivity in this layer lowers device temperature, improves power handling, reduces size, and extends lifespan.
Aluminum Base
The third layer is the aluminum substrate, which has high thermal conductivity. It helps dissipate heat efficiently, ensuring stable performance in high-power applications.
Aluminum Base Membrane Layer
This protective layer prevents the aluminum surface from scratches and unwanted etching. It is available in two types: one withstands temperatures below 120°C, while the high-temperature version resists up to 250°C.
Common Types of Aluminum PCBs
1-Layer
This is the simplest type. The circuit is directly etched onto the copper layer of the aluminum laminate. Heat travels from the components to the copper layer, then passes through the PP layer and into the aluminum base for effective dissipation.
2-Layer
Has two copper layers and two PP layers but only one side for components. Heat flows from the components to the first copper layer, then through the PP layers before reaching the aluminum base.
2-Layer Dual Component-Mounting
When one side just won’t cut it, that’s when we turn to a double-sided PCB. This type features copper PTH holes that are filled with resin, ensuring they’re nicely insulated from the aluminum base. The heat path remains similar—components transfer heat through the copper and PP layers before reaching the aluminum base.
4-Layer Dual Component-Mounting
Has two copper layers and two PP layers on each side. Heat moves from the external copper layer, through multiple PP and copper layers, and finally into the aluminum base. Thermal conductivity is lower than in single-layer or two-layer PCBs since heat must pass through more layers.

Thicknesses and Laminates of Aluminum PCB
When discussing aluminum PCBs, two crucial elements to consider are the thickness of the laminate and the type of material used. Aluminum PCB laminates consist of three distinct layers: the aluminum base, the PP layer, and the copper layer. The most common aluminum bases include materials like 1006, 3003, 5952, and 6061. These vary in strength and hardness. The higher the number, the stronger the material.
We can use Ventec laminates for our aluminum PCBs. For example, the VT-4B7 SP laminate comes in thicknesses ranging from 0.6mm to 3.0mm. It’s available with copper foil weights from 1/3oz to 6oz, and it offers thermal conductivity of 7W/mK. You can also choose another laminate for your aluminum PCB like Shengyi, Berquist or Arlon.

Aluminum PCBs handle heat better than standard boards. But what is the maximum temperature for aluminum PCB? Most can withstand up to 110°C before performance drops. Some designs go higher, but that depends on the Aluminum PCB design guidelines / rules (IMS / MCPCB) used. These boards work well between -40°C and 110°C in most cases. If you need exact numbers, you can reach out to us to know more about aluminum PCB.
Not necessarily. Most aluminum PCBs use a single-layer design, where the copper traces sit on top and the aluminum base provides heat dissipation. In this setup, components are mounted on the same side as the copper, making it the “solder side.”
Some manufacturers offer double-sided IMS PCBs, allowing more flexibility. Keep in mind that electrically connecting the aluminum substrate to the circuit is not straightforward and usually requires special processing.
Using through-hole components on an aluminum PCB is tricky. Unlike standard FR4 boards, aluminum PCBs typically have a single copper layer on top, with the metal base acting as a heat sink. This means drilled holes do not have insulation unless special processing is used.
If you place pads around the holes, the exposed aluminum can create shorts. Most aluminum PCBs are designed for surface-mount components only. If through-hole mounting is necessary, you might need an insulating layer around the holes or use special SMT sockets for your connections.

Performance of Aluminum PCB
Aluminum PCBs stand out for their excellent heat management. Regular PCB materials like FR4 and CEM3 struggle with heat dissipation. If heat builds up, electronic components can overheat and fail. Aluminum PCBs prevent this by pulling heat away from components, keeping everything cooler and more reliable.
They also handle thermal expansion better. Different materials on a PCB expand and contract at different rates when heated. This can cause stress on components and weaken connections. Aluminum PCBs reduce this problem, improving the durability of the whole system. This is especially useful in SMT (surface mount technology) applications, where precision is key.
Dimensional stability is another advantage. When exposed to heat, aluminum PCBs change size far less than standard insulating materials. From 30°C to 150°C, their expansion is minimal—only about 2.5% to 3%.
Beyond that, aluminum PCBs offer shielding against interference, replace fragile ceramic boards, and improve heat resistance. They also help lower production costs by reducing the need for extra cooling solutions.

They also handle thermal expansion better. Different materials on a PCB expand and contract at different rates when heated. This can cause stress on components and weaken connections. Aluminum PCBs reduce this problem, improving the durability of the whole system. This is especially useful in SMT (surface mount technology) applications, where precision is key.
Dimensional stability is another advantage. When exposed to heat, aluminum PCBs change size far less than standard insulating materials. From 30°C to 150°C, their expansion is minimal—only about 2.5% to 3%.
Beyond that, aluminum PCBs offer shielding against interference, replace fragile ceramic boards, and improve heat resistance. They also help lower production costs by reducing the need for extra cooling solutions.

Common Types of Aluminum PCBs
1-Layer
This is the simplest type. The circuit is directly etched onto the copper layer of the aluminum laminate. Heat travels from the components to the copper layer, then passes through the PP layer and into the aluminum base for effective dissipation.
2-Layer
Has two copper layers and two PP layers but only one side for components. Heat flows from the components to the first copper layer, then through the PP layers before reaching the aluminum base.
2-Layer Dual Component-Mounting
When one side just won’t cut it, that’s when we turn to a double-sided PCB. This type features copper PTH holes that are filled with resin, ensuring they’re nicely insulated from the aluminum base. The heat path remains similar—components transfer heat through the copper and PP layers before reaching the aluminum base.
4-Layer Dual Component-Mounting
Has two copper layers and two PP layers on each side. Heat moves from the external copper layer, through multiple PP and copper layers, and finally into the aluminum base. Thermal conductivity is lower than in single-layer or two-layer PCBs since heat must pass through more layers.

Thicknesses and Laminates of Aluminum PCB
When discussing aluminum PCBs, two crucial elements to consider are the thickness of the laminate and the type of material used. Aluminum PCB laminates consist of three distinct layers: the aluminum base, the PP layer, and the copper layer. The most common aluminum bases include materials like 1006, 3003, 5952, and 6061. These vary in strength and hardness. The higher the number, the stronger the material.
We can use Ventec laminates for our aluminum PCBs. For example, the VT-4B7 SP laminate comes in thicknesses ranging from 0.6mm to 3.0mm. It’s available with copper foil weights from 1/3oz to 6oz, and it offers thermal conductivity of 7W/mK. You can also choose another laminate for your aluminum PCB like Shengyi, Berquist or Arlon.

Frequently Asked Questions
| Feature | FR4 PCB | Aluminum PCB |
| Material | Fiberglass with epoxy resin | Aluminum or copper core with insulation |
| Thermal Conductivity | Low | High (better heat dissipation) |
| Mechanical Strength | Rigid and durable | Strong, especially in harsh environments |
| Applications | Consumer electronics, general circuit boards | LED lighting, power electronics, automotive |
| Cost | More affordable | More expensive |
| Dielectric Losses | Low (better signal integrity) | Higher (not ideal for high-frequency use) |
Aluminum PCBs handle heat better than standard boards. But what is the maximum temperature for aluminum PCB? Most can withstand up to 110°C before performance drops. Some designs go higher, but that depends on the Aluminum PCB design guidelines / rules (IMS / MCPCB) used. These boards work well between -40°C and 110°C in most cases. If you need exact numbers, you can reach out to us to know more about aluminum PCB.
Not necessarily. Most aluminum PCBs use a single-layer design, where the copper traces sit on top and the aluminum base provides heat dissipation. In this setup, components are mounted on the same side as the copper, making it the “solder side.”
Some manufacturers offer double-sided IMS PCBs, allowing more flexibility. Keep in mind that electrically connecting the aluminum substrate to the circuit is not straightforward and usually requires special processing.
Using through-hole components on an aluminum PCB is tricky. Unlike standard FR4 boards, aluminum PCBs typically have a single copper layer on top, with the metal base acting as a heat sink. This means drilled holes do not have insulation unless special processing is used.
If you place pads around the holes, the exposed aluminum can create shorts. Most aluminum PCBs are designed for surface-mount components only. If through-hole mounting is necessary, you might need an insulating layer around the holes or use special SMT sockets for your connections.
