High-Quality Aluminum PCBs with Competitive Pricing
Our PCB Assembly Capabilities
If someone knows that aluminum PCBs are a particular type of printed circuit board that uses aluminum as a substrate, then we can tell that person knows a lot about the PCB industry. For example, some familiar with the PCB industry may say, “These PCBs are commonly used in applications that require high thermal conductivity, heat resistance, and durability, right?” Yes, you got the point.
If someone says that, like fibreglass or plastic substrates, Aluminium PCBs are susceptible to scratches, cracks, and other physical damage, that statement is false and very different from the truth. They are used in various products, from LED lights and power supplies to automotive signalling and lighting, smart home applications, aerospace, and medical devices. They are becoming increasingly popular due to their excellent thermal conductivity and consequent ability to dissipate a high heat level, improving product lifespan and reliability.
In short, if Aluminum printed circuit boards do not provide higher performance and more excellent durability, then projects for these electronic applications will have difficulty succeeding.

Advantages of Aluminum PCBs: Why They Stand Out
The Design of Aluminum PCBs
Suppose someone knows that aluminum circuit board design requires some special considerations. In that case, he understands that aluminum substrates have different characteristics or properties than traditional substrates such as fibreglass or plastic. When designing an Aluminium PCB board, the substrate material needs to be considered, along with the number of layers, the track width, and electrical component placement. Grounding and transmission line design are also crucial due to the high conductivity of aluminum.
Regarding electrical performance, signal integrity must be considered since aluminum is much more conductive than fibreglass, causing a higher impedance than a PCB with similar construction on a fibreglass substrate. Therefore, careful selection of the signal trace width, component placement, routing, and via design plays a vital role in ensuring the integrity of signals at higher frequencies.
Overall, the design process for an aluminum circuit board involves understanding its unique properties and tailoring the design to maximize its thermal and electrical performance. Detailed thermal simulations, controlled impedance calculations, RF best practices, and grounding techniques are vital to the design’s success. So alumimum PCB design is very important to get the best LED products.
The Manufacturing Process of Aluminum PCBs
It is wrong to think that the manufacturing process of Aluminium PCB is the same as the traditional PCB manufacturing process. Instead, the manufacturing process of aluminum substrate PCBs involves the following steps:
Thermal Management of Aluminum PCBs
The thermal management of aluminum PCBs involves the transfer of heat from the electronic components to the substrate and then to the environment. Aluminium PCBs have been designed with a metal-coated layer that increases the heat transfer rate by up to 10 times compared to FR4 PCBs to facilitate this process. Is there a better way to extend the life of a PCB and maintain optimal performance over time than by promoting effective heat transfer and dissipation? The answer is no.
Applications of Aluminum PCBs: Where You’ll See Them
To sum up, aluminum circuit boards are used in applications that require high-reliability electronics, high-temperature applications or high-power automotive, aerospace, telecommunications, and many other areas characterized by their durability, thermal management and toughness. So aluminum PCB for LED are widely used in many industry areas.
Concerns with Aluminum PCBs: Things to Keep in Mind
Best Practices for Prototyping and Manufacturing Aluminum PCBs
Design with Thermal Management in Mind: Design the PCB with proper heat sink design and select insulation material for the layers with appropriate thermal conductivity to ensure optimal heat dissipation of the PCB.
The consequences can be imagined if you work with an unreliable PCB manufacturer. Your desire to produce PCBs with better quality and optimal performance will be defeated.
In brief, the best practices for prototyping and manufacturing Aluminium PCB boards include the following:
By following the mentioned best practices, manufacturers can achieve high performance and longevity from Aluminium PCB designs.

The manufacturing difficulty of Aluminum PCB depends on the specific situation.
Due to their unique properties, Aluminum PCBs will be more expensive than FR-4 PCBs.
It takes two days to five weeks for aluminum PCB. The specific delivery time depends on the customer’s requirements.
Yes, aluminum PCBs made in Viasion are RoHS-compliant. We follow RoHS standards to manufacture all of our products.
Aluminum circuit boards is one kind of MCPCBS. Aluminium based PCB, copper based PCB, Iron based PCB and other alloy based PCBs are all MCPCBS.
A typical aluminum board includes the following parts: aluminum base, dielectric and copper trace.
If the customer requires a particular soldering method for aluminum PCBs, we will manufacture Aluminum PCBs according to the customer’s requirements.
There are many similarities between aluminum PCBs and FR4 PCBs in manufacturing or technology. However, aluminum PCB is an advanced PCB, and its manufacturing process still has exceptional characteristics and needs strict and effective management and control.
1) Aluminum PCBs dissipate heat significantly better than standard FR-4 structures.
2) Aluminum PCBs use a dielectric typically 5 to 10 times the thermal conductivity of conventional epoxy glass and 1/10 the thickness.
3) The heat transfer index of aluminum PCBs is more effective than the heat transfer index of traditional rigid PCBs.
Yes, Viasion supply single layer aluminum circuit boards, double sided aluminum circuit boards including thermoelectric separation structure, and also mutilayer MCPCBS.
Their main differences are:
1) Different materials are used;
2) Different usage. Aluminum boards are always used in LED and lighting products, but FR4 almost used in all industry areas.
