Aluminium PCB manufacturing process, PCB assembly factory

Friday, August 1st, 2025

As a professional aluminum PCB manufacturer, Best Technology delivers reliable, cost-effective solutions with a complete in-house aluminium PCB manufacturing process—from raw material sourcing to final assembly.

How is aluminium PCB made?

Unlike standard FR4 boards, aluminium boards require special materials, customized layering, and high-precision etching to perform reliably under high temperatures.

It begins with a base of aluminium, selected for its thermal conductivity and strength. This base acts as the backbone of the entire structure. Over this, a dielectric layer is added—a thermally conductive yet electrically insulating material. This layer allows heat to pass through to the metal core without shorting the circuit.

Next comes the copper foil. This conductive layer is laminated onto the dielectric using heat and pressure. Once bonded, the copper is patterned using photolithography. Then, etching forms the conductive tracks that carry current across the board.

Finally, the surface is coated with a protective solder mask. The board is drilled, tested, and cut into its final shape, ready for assembly. Every step is controlled to ensure high precision and reliability.

What are the raw materials for aluminum manufacturing?

For aluminium PCBs. The base material is an aluminium alloy, often 5052 or 6061, known for corrosion resistance and good mechanical performance. These alloys are lightweight yet robust, ideal for handling mechanical stress and thermal loads.

Next is the dielectric layer. Typically made of epoxy resin or a ceramic-filled polymer, this layer must be thermally efficient. The goal is to transfer heat quickly without compromising electrical insulation.

The conductive layer is pure copper, usually between 1oz and 3oz thick. This copper sheet is what gets etched to form the traces. To finish, a solder mask is applied to protect the copper and prevent short circuits.

Each material plays a crucial role. Choosing the right combination impacts performance, durability, and cost. That’s why experienced manufacturers like Best Technology take material quality and testing very seriously.

What are the layers of aluminum PCB?

Unlike traditional PCBs, these boards typically have three core layers:

Copper Layer: It’s where all the routing happens. The thickness varies based on current load, usually between 35μm and 105μm.

Dielectric Layer: It insulates the circuit while transferring heat to the metal base. Its thickness affects thermal resistance.

Aluminium Base Layer: This bottom layer supports the entire board. It also acts as a heat sink, dissipating excess energy and maintaining stable temperatures.

What are the manufacturing processes for Aluminium?

The aluminium PCB manufacturing process differs slightly from FR4, due to the metal base and heat-sensitive applications.

Material Preparation: Aluminium base sheets are cleaned and coated with the dielectric layer.

Copper Lamination: A copper foil is bonded using thermal pressure.

Image Transfer: Photolithographic techniques are used to apply the circuit pattern.

Etching: Unwanted copper is removed, leaving the circuit traces.

Drilling: Holes are drilled for vias and mounting points.

Plating: If needed, through-holes are plated for multi-layer connectivity.

Solder Mask Application: A protective coating is applied to prevent oxidation.

Silkscreen Printing: Labels, logos, and identifiers are printed.

Surface Finish: ENIG, HASL, or OSP finishes are applied based on customer needs.

Final Testing: Each board is electrically tested for continuity and shorts.

Routing and Packaging: Boards are cut, inspected, and packed for delivery.

Every step must meet tight tolerances. Even minor defects can affect performance, especially in LED, automotive, and power systems.

What are the pros and cons of aluminum PCB?

Aluminium PCBs have their strengths—and a few limitations.

Pros:

Superior Heat Dissipation: Aluminium spreads heat fast. This reduces hotspots and extends component life.

High Mechanical Strength: These boards are robust, reducing the risk of cracks and warping.

Lightweight Yet Durable: Aluminium provides rigidity without the weight of steel or ceramic.

Cost-Effective: Compared to ceramic substrates, aluminium PCBs are more affordable for high-performance needs.

Eco-Friendly: Aluminium is recyclable, making it a greener choice.

Cons:

Limited Flexibility: Aluminium is rigid. It’s not suitable for flexible PCB applications.

Single-Sided Complexity: Most aluminium PCBs are single-layered. Multi-layer designs are possible but more complex and costly.

Processing Requirements: Special tools are needed for drilling and etching, raising initial setup costs.

Still, the benefits far outweigh the downsides in most high-power applications. That’s why aluminium boards dominate industries like LED, power electronics, and automotive lighting.

How thick is aluminum PCB?

Thickness matters. It affects strength, heat transfer, and overall reliability.

For aluminium PCBs, the metal base typically ranges from 0.8mm to 3.2mm. The most common thickness is 1.6mm, offering a good balance between strength and heat dissipation. Some high-power applications may use up to 5mm for extra thermal control.

Thickness also depends on the product’s end use. For compact devices like LED bulbs, thinner substrates are preferred. For industrial use, thicker bases ensure long-term performance under heavy loads.

What is the thermal resistance of aluminum PCB?

Thermal resistance is crucial. It determines the heat dissipation performance of the PCB board. The lower the thermal resistance, the better the heat transfer effect, which is one of the advantages of aluminum PCB boards.

A typical aluminium PCB has a thermal resistance between 0.3°C/W and 1.0°C/W. The exact value depends on the dielectric material and its thickness.

The dielectric is designed to transfer heat quickly from the copper layer to the metal base. This lowers component temperature, improves performance, and extends lifespan.

How thick is the dielectric layer of aluminum PCB?

The dielectric layer not only ensures the passage of heat, but also acts as an insulator. The thickness of the dielectric layer directly affects the insulation performance and thermal resistance.

Most dielectric layers are between 50μm and 150μm thick. Thinner layers offer better heat transfer but may reduce electrical insulation. Thicker layers improve isolation but limit thermal performance.

Choosing the right thickness is about balance. It depends on voltage requirements, power density, and end-use environment.

How do aluminium PCBs work?

Aluminium PCBs work by balancing three critical needs: electrical conduction, mechanical support, and heat dissipation. They combine a conductive copper layer with a heat-spreading aluminium base, connected by a special dielectric.

When current flows through the copper traces, it generates heat. The dielectric layer moves this heat down to the aluminium base, which then spreads it across the board and out to the environment. This keeps components cool, even under heavy load.

When to use aluminum PCB?

Aluminum PCBs are widely used in applications where heat is an issue. That includes:

LED Lighting: Heat control improves brightness, lifespan, and efficiency.

Power Supplies: High-current paths stay cool and stable.

Automotive Electronics: High vibration resistance is perfect for engine bays and dashboards.

Communication Equipment: Enhanced thermal management ensures signal reliability.

Industrial Controllers: Strong mechanical support reduces failure under stress.

If your design involves high-power components or tight thermal tolerances, aluminium PCBs are the solution.

Conclusion:

Aluminum substrates have good thermal conductivity, mechanical strength and cost-effectiveness. Whether you’re building LED lights, industrial controls, or automotive systems, aluminium PCBs provide a solid foundation. Their superior heat management protects components, improves efficiency, and extends service life.

What is the Sophisticated Embedded Copper Technology?

Thursday, July 31st, 2025

Embedded copper technology is a specialized PCB manufacturing process that enhances current handling and thermal performance by embedding copper directly into the board’s layers. In the realm of printed circuit board (PCB) manufacturing, efficient heat dissipation is a critical factor, especially as electronic devices become more compact and powerful. One innovative solution that addresses this challenge is embedded copper technology. This process involves embedding copper blocks in specific areas of the board, allowing direct thermal transfer from heat-generating components to the copper, thereby achieving rapid heat dissipation. Let’s delve into the details of this technology, including its types, key parameters, and material requirements.

Why Top Telecom Brands Choose Embedded Copper Technology?

Understanding Embedded Copper Technology

At its core, embedded copper technology is all about strategic thermal management. By embedding copper blocks in localized regions of the PCB, the heat from components in contact with these blocks is quickly conducted away, preventing overheating and ensuring the reliable operation of the electronic device. Embedded copper technology comes in two main types:

Through – embedded type: As the name suggests, this type involves embedding the copper block completely through a certain section of the board, creating a direct thermal path through that part of the PCB structure.
Semi – embedded type: Here, the copper block is only partially embedded into the board, still enabling effective heat transfer but with a different structural integration compared to the through-embedded type.

Understanding Embedded Copper Technology

Key Parameters and Characteristics

To ensure the successful implementation of buried embedded technology, several key parameters and characteristics must be considered.

Copper Thickness

The thickness of the red copper used in buried copper applications varies to meet different thermal and structural needs. Common thicknesses include 0.5mm, 0.6mm, 0.8mm, 1.0mm, 1.2mm, 1.6mm, 1.8mm, 2.0mm, 2.5mm, 3.0mm, 3.2mm, and 3.5mm.

Copper Block Thickness Capability

The normal thickness of the buried copper block is ≥1.0mm, with an extreme minimum thickness of 0.5mm. If the copper block thickness is less than 1.0mm, an unconventional review is required to assess the feasibility and potential challenges.

Relationship Between Copper Block Thickness and Grooved Materials

The thickness of the copper block is closely related to the combined thickness of the grooved prepreg (PP) and grooved core board:

For red copper with a thickness of 0.5-0.6mm, the copper block thickness is equal to the combined thickness of the grooved PP and grooved core board.
For 0.8mm red copper, the copper block thickness is 0-0.05mm thicker than the combined thickness of the grooved PP and grooved core board.
For red copper with a thickness of ≥1.0mm, the copper block thickness is 0.05 – 0.1mm thicker than the combined thickness of the grooved PP and grooved core board.

Copper Block Dimensions

The normal size of the embedded copper block is ≥3x3mm, with an extreme minimum size of 2.5×2.5mm. This ensures that the copper block can effectively perform its thermal conduction function while fitting into the PCB design.

PP Material Requirements

At least 2 sheets of interlayer PP should be used, and priority is given to PP with a high resin content. If the board thickness allows, it is best to use 2 sheets of 1080 PP with high resin content, and it can also be mixed with 106, 3313, 2116, and 7628 PP.
The commonly used PP material is FR-4. For special board materials such as TU-872SLK/M6/SH260/FR-27/FR-28, unconventional review and verification of the PP are required.
Additionally, the prepreg cannot use Rogers4450F, as this type of PP has poor fluidity, making it difficult to fill the gaps of the embedded copper, and the bonding force between the PP and red copper is relatively weak

What Industries Use Embedded Copper Technology?

Embedded copper technology, valued for its strong heat dissipation, is widely used in industries requiring effective PCB thermal management. Here are key application areas:

Telecommunications

High-power devices like 5G base stations and routers generate much heat. Embedded copper in their PCBs prevents overheating, ensuring stable signal transmission and equipment longevity.

Automotive Electronics

Modern cars, especially EVs, have heat-generating systems like ECUs, ADAS, and powertrains. Embedded copper PCBs manage this heat, boosting efficiency and reliability, e.g., ensuring accurate ECU operation for better fuel efficiency.

Industrial Automation

Robotics, PLCs, and motor drives in factories run continuously, producing significant heat. Buried copper keeps temperatures in check, ensuring consistent performance and reducing downtime, like enabling precise robotic arm movements.

Medical Devices

High-power medical equipment (MRI, CT scanners) needs reliable components. Buried copper in their PCBs dissipates heat efficiently, preserving device accuracy and safety for diagnostics and treatments.

What is the Difference between Embedded Copper Technology and Embedded Copper Coin Technology?

While both embedded copper technology and embedded copper coin technology aim to improve thermal and electrical performance in PCBs, they differ in structure, purpose, and manufacturing approach. These differences affect how each is used in real-world applications, especially where high power or efficient heat transfer is needed. Understanding these distinctions can help you choose the right solution for your specific design requirements. Key Points for Understanding the Differences:

Construction Method:
- Embedded copper uses etched copper patterns within PCB layers.
- Embedded copper coin involves physically inserting a solid copper piece into a cavity in the PCB.
Thermal Efficiency:
- Copper coin technology offers better localized heat dissipation due to the solid metal insert.
- Embedded copper layers dissipate heat over a wider area but are less efficient for hotspots.
Material Usage:
- Copper coin PCBs use more copper material per unit and may require custom milling and placement techniques.
Electrical Performance:
- Both methods enhance current capacity, but embedded copper coin PCBs can handle very high current due to the solid insert.
Manufacturing Challenges:
- Embedded copper coin PCB manufacturing needs precise cavity creation, bonding, or soldering, while embedded copper PCBs rely more on layer alignment and lamination.
Cost Impact:
- Embedded copper coin PCBs are generally more expensive due to the complexity of coin placement and material cost.
Application Suitability:
- Choose embedded copper technology for compact, high-layer PCBs needing better current paths.
- Opt for embedded copper coin technology when you need extreme thermal management in power-dense areas.

What is an MCPCB LED Strip? MCPCB Design

Thursday, July 31st, 2025

An MCPCB LED strip is an LED light strip built on a Metal Core PCB instead of a regular fiberglass board. The metal base, usually aluminum, helps pull heat away from the LEDs. This keeps them cooler, brighter, and longer-lasting.

What is MCPCB LED?

An MCPCB LED strip is a flexible or rigid lighting circuit that uses Metal Core Printed Circuit Boards (MCPCB) instead of traditional fiberglass boards. These boards are made with a metal base—often aluminum—layered with a dielectric material and topped with copper circuitry.

The main advantage? Superior heat dissipation. LED chips generate heat, and if it’s not managed properly, brightness fades and lifespan drops. The metal core acts as a thermal bridge, quickly pulling heat away from the LEDs.

Why use MCPCB for LED strip lights?

LED light strips are widely used for their compact size and bright output, but they also bring a problem: heat. Excessive heat shortens LED life, dims the light, and can even cause circuit failure.

Here’s where MCPCB LED steps in with its unique benefits:

High thermal conductivity: Metal cores rapidly remove heat from LED chips.

Longer lifespan: Cooler LEDs mean longer use.

More stable output: No flickering or fading over time.

Compact design support: Even tight spaces can house high-powered LEDs safely.

Durability: Metal cores are more resistant to physical damage than FR4 boards.

How does MCPCB design affect LED strips?

The MCPCB design is more than just the layout of circuits. Each layer of the MCPCB is chosen and designed for a specific function:

Metal base (usually aluminum): Carries the heat away.

Dielectric layer: Transfers heat while keeping electrical isolation.

Copper circuit layer: Routes electricity to the LEDs.

Even the thickness of the dielectric layer impacts how fast heat can move. A thinner dielectric means faster transfer, but it must still insulate properly. Similarly, thicker copper can handle higher currents without overheating.

Good MCPCB design ensures even temperature distribution. That means no LED on the strip gets too hot. Even light, long life, and better performance.

Can MCPCB design improve LED lifespan?

Absolutely. Heat is the main enemy of LED lifespan. Every degree of temperature rise reduces the life of an LED chip.

Traditional PCB materials like FR4 don’t handle heat well. Over time, they allow hotspots to build up. These hotspots degrade the LED’s light output and can eventually cause failure.

But MCPCB design changes the game. By channeling heat away from the LED source, it keeps the chip temperature lower. This cooler environment means:

No yellowing of lenses

No cracking of solder joints

No degradation of LED chip efficiency

So yes, MCPCB LED strips don’t just shine brighter—they shine longer.

MCPCB LED vs. regular LED PCB strip – what’s better?

Let’s compare a regular LED PCB strip to a metal core version:

Feature	Regular LED Strip (FR4)	MCPCB LED Strip
Heat dissipation	Poor	Excellent
Brightness over time	Decreases	Maintained
Durability	Fragile	Rugged
Power handling	Low	High
Cost	Lower upfront	Better long-term value

While FR4-based LED strips may seem cost-effective, they often end up needing frequent replacements—especially in high-power applications. MCPCB LED strips, on the other hand, are built to last.

How to choose the right LED PCB strip?

Choosing the right LED PCB strip depends on your application. Here are a few factors to consider:

Heat Load: If your strip is in a confined or warm space, go for MCPCB.

Power Requirement: More power means more heat. MCPCB handles high current safely.

Installation Area: Metal core strips are ideal for industrial, automotive, and high-brightness home uses.

Budget vs. Longevity: While MCPCB may cost more upfront, it saves money in the long run.

Brightness and Color Consistency: Heat can affect color temperature. MCPCB avoids this.

How to customize an MCPCB LED strip?

Customization is one of the most important aspects of MCPCB design. With the right manufacturer, you can tailor almost everything:

Board size and shape: Fit into curves, tight corners, or irregular enclosures.

Copper thickness: For heavy-duty current or low-voltage precision.

Thermal conductivity: Select different dielectric materials for performance.

LED configuration: Control spacing, brightness, and light pattern.

Mounting features: Add connectors, screw holes, or adhesive backs.

Surface finish: Choose between ENIG, HASL, OSP for different protection levels.

When you work with a professional manufacturer like Best Technology, your custom MCPCB LED strip lights will be the best they can be.

Where is MCPCB LED used most?

You’ll find MCPCB LED strips in places that demand both performance and reliability. Here are just a few common uses:

Automotive lighting: Headlights, tail lamps, and interior accents.

Commercial lighting: Display cases, signage, and architectural lights.

Medical devices: Surgical lights and diagnostic equipment.

Industrial machines: Workstation lighting, control panels.

Consumer electronics: High-end flashlights, monitors, smart mirrors.

Streetlights & floodlights: Large scale applications with heavy thermal loads.

Wherever durability meets brightness, MCPCB LED plays a vital role.

Conclusion:

MCPCB LED strips surpass traditional LED PCB light strips in every way with better heat management, longer lifespan, and greater durability.

What is Cu Inlay PCB? Copper Inlay PCB Market

Thursday, July 31st, 2025

A Cu inlay PCB, also called copper inlay PCB or bus bar PCB, is designed to manage high current flow and heat dissipation in modern electronic systems. As electronic devices become more compact and powerful, the need for better power handling within limited space grows rapidly. Standard copper traces often can’t handle high current without overheating or losing efficiency. That’s where copper inlay PCBs offer a smart and effective solution.

At Best Technology, we specialize in custom copper inlay PCBs, supporting demanding industries like automotive, industrial control, and renewable energy. We use advanced techniques to embed copper bars directly into PCBs, helping your products perform better and last longer.

What Is Cu Inlay PCB?

A Cu inlay PCB is a circuit board where solid copper blocks or bars are inserted into the board structure. These copper inlays are physically placed into slots or cutouts in the base material of the PCB, often FR4, aluminum, or other substrates.

The copper inlay becomes part of the circuit, connecting to surrounding copper traces and components. Instead of relying on thin copper layers, which might struggle with high current, thick copper inlays offer a low-resistance path for electricity and a direct route for heat dissipation.

These PCBs are sometimes known as bus bar PCBs because the inlay acts like a mini bus bar embedded inside the board. They are often found in designs where power density is high, and the space for external power routing is limited.

What is Cu Inlay PCB? Copper Inlay PCB Market

What Is the Working Principle of Inlay Copper in PCB?

In a copper inlay PCB, the working principle revolves around using solid copper bars to conduct electricity and transfer heat efficiently. Here’s how it works:

Precision Cutouts: During the PCB manufacturing process, slots or grooves are milled into the base material to fit the copper inlays.
Copper Insertion: A solid copper bar or block is placed into each slot, making it part of the board structure.
Electrical Connection: The inlay is then electrically connected to surrounding copper traces. This can be done via plated-through holes, soldering, or lamination, depending on the design.
Heat Transfer: When high current flows through the board, the copper inlay not only carries the current but also absorbs and spreads heat. This helps prevent overheating and improves the reliability of the entire system.

Because copper has high electrical and thermal conductivity, the inlay serves two purposes: reducing voltage loss and keeping temperatures low.

Why Inlay Copper in the PCB?

The main reason to use inlay copper in a PCB is to manage high current and heat in a compact space. In many power electronic devices, standard copper layers are too thin to carry heavy current without voltage drops or overheating. Here are key reasons to choose copper inlay PCB:

High Current Needs: When your design must carry more than 20-100 amps of current, copper inlays provide a path that minimizes power loss.
Thermal Control: Devices with power-hungry components, such as power MOSFETs, IGBTs, or coils, generate a lot of heat. Copper inlays help pull heat away from these hot spots.
Space Limitations: Using thick copper over the entire PCB increases cost and thickness. Copper inlay allows selective reinforcement, only where needed.
Improved Design Flexibility: Copper inlays can be designed into specific regions, enabling multi-zone current paths and optimized thermal management.

In short, inlay copper in PCB helps engineers create more reliable, efficient, and compact systems.

Benefits of Copper Inlay PCB

1. With a copper inlay, your PCB can safely carry high current levels (often over 100A) without the risk of burning or damage. The solid copper inlay has low resistance, which minimizes energy loss.

2. Copper inlays absorb heat from nearby components and transfer it efficiently to heat sinks or metal housings.

3. Instead of using bulky external bus bars or thick copper layers, copper inlays offer a space-saving option. They let you design smaller PCBs with higher performance, which is ideal for portable or space-constrained products.

4. The solid metal insert adds strength to the PCB structure. It prevents board bending or warping and supports heavy components mounted on top.

Copper Core PCB vs Copper Inlay PCB

Some engineers may wonder: should I choose copper core PCB or copper inlay PCB? Both types are designed to improve heat management and electrical performance, but they use different structures and serve different needs.

A copper core PCB is a type of metal core PCB, uses a solid copper plate as the base material. This copper core acts as a heat spreader, helping to quickly transfer heat away from the entire board. It is ideal for applications where even heat distribution is required across a large area.

In contrast, a copper inlay PCB typically uses FR4 or other insulating materials as the base, with copper bars inserted into machined slots only in selected areas. These copper inlays handle high current directly and provide localized thermal management exactly where it’s needed.

Feature	Copper Core PCB	Copper Inlay PCB
Copper Placement	Full copper plate inside the PCB	Copper bar inserted into slots
Heat Management	Uniform heat spread across the board	Targeted heat dissipation
Current Handling	Good, but may require thick PCB	Excellent, at specific points
Flexibility in Design	Less flexible, fixed copper plate	Flexible, inlays only where needed
Cost	Higher due to full copper layer	More cost-effective (selective use)

In summary, copper core PCBs are best for broad heat dissipation, while copper inlay PCBs are preferred when you need high current capacity in specific zones with better design flexibility and material savings.

Factors Affect Copper Inlay PCB Price

The price of copper inlay PCBs can vary widely based on your design needs, order volume, and technical requirements. Several factors directly affect the cost:

1. Copper Inlay Size and Thickness

Larger and thicker copper bars increase both material and machining costs. Inlays typically range from 1mm to 5mm thick. Thicker copper costs more due to higher copper usage and longer machining time.

2. Board Size and Layers

Larger PCBs and multi-layer designs involve more material, labor, and processing steps, leading to higher costs.

3. Surface Finishes and Testing

Special surface finishes like ENIG, immersion silver, or selective gold plating, as well as full electrical or thermal testing, can add to the overall cost.

4. Order Quantity

Larger orders benefit from volume discounts, while small batches have higher unit prices due to setup and tooling time.

5. Price Range

For reference, the typical price range for copper inlay PCBs is approximately:

Prototype or low volume: $300 – $800 per square meter
Medium volume: $200 – $400 per square meter
Mass production: $100 – $250 per square meter

Note: These are estimated ranges. Actual prices depend on copper inlay dimensions, layer count, complexity, and finish options.

The 2025 Ultimate Guide to PCB Aluminium Substrate

What Is PCB Aluminium Substrate?

PCB aluminium substrate is a special type of printed circuit board that uses aluminium as its base material. This metal base helps in managing heat more effectively compared to standard materials like FR4. It supports better thermal flow, which is key in modern compact devices. This substrate usually includes three layers: the aluminium base, a dielectric layer for insulation, and a copper layer for the circuit.

What Is the Difference: Aluminum PCB vs FR4?

Choosing between aluminium PCB and FR4 often depends on the application. Aluminum PCB vs FR4 mainly differs in heat management. FR4 is a common glass-reinforced epoxy material with low heat transfer. In contrast, aluminium PCB quickly removes heat from components. Aluminium boards also offer higher durability and support higher current loads. On the other hand, FR4 is more flexible for complex circuits but not suitable for high-power or high-temperature tasks.

Feature	Aluminum PCB	FR4 PCB
Base Material	Aluminum metal	Glass-reinforced epoxy resin
Thermal Conductivity	High (1.0–3.0 W/m·K)	Low (0.25–0.3 W/m·K)
Heat Dissipation	Excellent	Poor
Mechanical Strength	Strong and rigid	Moderate strength
Flexibility in Design	Limited	High (supports multilayer and flexible)
Current Carrying Capacity	High	Moderate
Cost per Unit	Higher than FR4	Lower than aluminum PCB
Typical Applications	LED lighting, power modules, automotive	Consumer electronics, communication
Temperature Resistance	High	Lower
Weight	Heavier	Lighter
Durability	Very durable	Less durable under high heat

What Is Aluminum PCB Dielectric Material?

The dielectric layer in an aluminium PCB is key for thermal transfer and electrical insulation. This layer sits between the aluminium base and the copper circuit. It is usually made from thermally conductive material, helping move heat away from the circuit. The quality and thickness of this layer affect both the performance and price of the board. At Best Technology, we use high-grade dielectric to ensure low thermal resistance and high reliability.

What Is the PCB Aluminium Substrate Price?

The PCB aluminium substrate price can vary based on factors like board size, copper thickness, and thermal needs. Basic aluminium boards for LEDs are quite affordable, while complex ones for power electronics cost more. Bulk orders often reduce the unit cost. At Best Technology, we offer competitive rates with added value from expert support and quality control.

How to Choose PCB Substrate Types?

Selecting PCB substrate types depends on your project needs. Consider heat levels, power load, size, and cost. If your design generates much heat or requires high strength, aluminium is ideal. For less heat and lower costs, FR4 might work. There are also ceramic and flexible substrates for special cases. Our engineers at Best Technology help customers pick the right substrate by reviewing their designs and offering practical advice.

Criteria	Aluminum PCB	FR4 PCB	Ceramic PCB	Flexible PCB
Thermal Conductivity	High	Low	Very High	Low

What Is Single Sided Copper PCB?

A ‌single sided copper PCB‌ is the simplest type of printed circuit board, consisting of a single conductive copper layer bonded to one side of an insulating substrate (usually FR-4 fiberglass or phenolic material). The opposite side remains uncoated, making it ideal for straightforward circuits. Components are mounted and soldered onto the copper side, while traces (circuit paths) are created by etching away unwanted copper.

What is Aluminium Based PCB? Aluminum PCB vs. FR-4

Wednesday, July 30th, 2025

An aluminium based PCB is a powerful choice for modern electronics, especially where heat control matters. Whether you’re designing LED lights, power supplies, or automotive electronics, aluminium PCBs help you manage temperature, protect components, and deliver stable performance. Compared to standard boards, they offer better heat dissipation, which can make a big difference in product reliability.

At Best Technology, we manufacture high-quality aluminium PCBs using certified materials and advanced processes. With certifications like ISO9001, ISO13485 for medical devices, IATF16949 for automotive, and UL approval, we provide dependable circuit boards tailored to your needs.

Aluminium Based PCB Manufacturer

What Is Aluminium PCB?

An aluminium PCB—also called a metal core PCB (MCPCB)—is a type of printed circuit board that uses aluminium as the base material instead of the common fiberglass material (FR-4). The board consists of three main layers:

Aluminium base layer for strength and heat conduction
Insulating dielectric layer to separate the metal from the copper
Copper circuit layer for electrical connections

This structure helps draw heat away from heat-sensitive components like LEDs, transistors, or power devices. In simple terms, aluminium PCBs help keep things cool, especially in high-power or high-temperature applications.

What Are the Pros and Cons of Aluminum PCB?

Aluminium-based PCBs are made from low-alloy Al-Mg-Si series high-plasticity aluminium plates (structure shown in the figure below). These boards offer excellent thermal conductivity, electrical insulation, and machinability. Compared to traditional FR-4 boards, aluminium PCBs of the same thickness and trace width can carry higher current. They also feature dielectric breakdown strength up to 4500V and a thermal conductivity greater than 2.0 W/m·K. In the PCB industry, aluminium-based boards are the most widely used metal core PCBs. Key advantages include:

Support for Surface Mount Technology (SMT)
Highly efficient thermal diffusion in circuit design
Lower operating temperature, higher power density, high reliability, and longer product lifespan
Smaller product size, reducing both hardware and assembly costs
Replacement for fragile ceramic substrates, offering better mechanical durability

But they also have some limitations:

Lower flexibility: Aluminium boards cannot be bent like flexible PCBs.
More complex manufacturing: Special processes are needed to drill and etch metal-based boards.
Limited layers: Multi-layer aluminium PCBs exist, but they are harder and more expensive to produce.

At Best Technology, we help customers balance these factors. Our engineering team guides you through design and material selection to ensure your aluminium PCB works perfectly for your application.

Aluminium PCB Material Properties

Aluminium based PCB typically made from aluminium alloys like 5052, 6061, or 3003. These materials are chosen to handle heat well, maintain electrical insulation, and provide mechanical support. Some customers may confused about them and the differences between these materials. Here Best Technology listing the properties of each material, hope this can help you to choose which one is best for your project.

Property	5052 Aluminium	6061 Aluminium	3003 Aluminium
Composition	Al-Mg alloy	Al-Mg-Si alloy	Al-Mn alloy
Thermal Conductivity	~138 W/m·K	~167 W/m·K	~160 W/m·K
Electrical Conductivity	~35% IACS	~40% IACS	~40% IACS
Tensile Strength	210–230 MPa	260–310 MPa	130–180 MPa
Yield Strength	~130 MPa	~240 MPa	~115 MPa
Elongation	~12–20%	~8–10%	~10–20%
Corrosion Resistance	Excellent	Good	Very Good
Formability	Excellent	Good	Excellent
Machinability	Fair	Good	Fair
Cost	Moderate	Higher	Lower
Common Use in PCBs	LED lighting, power electronics	High-power, structural applications	Consumer electronics, general use

Quick Notes:

5052 is favored for excellent corrosion resistance and good thermal performance, often used in outdoor lighting PCBs or marine applications.
6061 offers better strength and machinability, suitable for mechanically demanding PCBs or large-size boards.
3003 is cost-effective with good thermal and corrosion resistance, ideal for low to moderate power electronic boards.

How Thick Is Aluminum PCB?

Aluminium PCBs vary in thickness based on design and applications needs. Common thicknesses range from 0.8mm to 3.2mm, but custom options are available. Here is a standard aluminium PCB thickness rules:

Single-layer boards: Typically range from 0.2mm to 0.5mm, suitable for simple circuit designs.
Double-layer boards: Generally 0.5mm to 1.2mm, balancing both signal transmission and heat dissipation needs.
Multi-layer boards: Thickness starts from 1.2mm and can reach up to 10mm, ideal for high-power electronic devices.

For applications with high thermal conductivity requirements (such as LED lighting and power electronics), aluminium PCBs may use thinner copper foil (ranging from 35μm to 280μm) laminated with the aluminium base. In such cases, the minimum board thickness can be as low as 0.075mm.

At Best Technology, we help customers choose the right thickness based on current flow, heat output, and mechanical strength. Thicker boards may cost more but offer better performance in demanding settings.

What Is the Maximum Temperature for Aluminium PCB?

Aluminium PCBs are built for high-temperature conditions. The dielectric layer determines the maximum working temperature, which typically ranges between 130°C to 150°C. Special materials can go higher, depending on the design.

Why is this important? In LED lighting or automotive power modules, excess heat can damage components. By using aluminium PCBs, you keep the temperature down and extend the life of your product. If you want to used in extreme high temperature applications, we have ceramic PCB that can achieve 850°C.

Aluminium PCB Manufacturing Process – Simplified

1. Material preparation: Select the right aluminium base, apply dielectric material, and add copper foil.

2. Drilling: CNC machines create holes for vias and component placement.

3. Circuit imaging: A photoresist is applied, and UV light is used to define the circuit pattern.

4. Etching: Unwanted copper is removed, leaving only the desired circuit.

5. Plating: Through-hole plating may be used if needed for connections.

6. Solder mask application: A protective layer prevents oxidation and solder bridging.

7. Surface finish: Common finishes include ENIG (Electroless Nickel Immersion Gold), HASL (Hot Air Solder Leveling), or OSP (Organic Solderability Preservative).

8. Testing: Electrical and thermal tests ensure each board performs as required.

Below is the detailed aluminium based PCB manufacturing process. Best Technology uses advanced MES systems for full traceability and tight quality control. We support both prototype runs and mass production with fast turnaround times.

How Does an Aluminium Based PCB Cost?

Several factors influence the cost of aluminium PCBs:

Material grade: Higher-quality aluminium and thermal materials cost more.
Board size and complexity: Larger boards or intricate designs increase price.
Copper thickness: Thicker copper adds to material and processing costs.
Surface finish: ENIG is more expensive than HASL or OSP.
Quantity: Bulk orders lower per-unit costs.

In general, aluminium PCBs cost more than FR-4 for simple designs but offer cost savings in thermal management. For example, using aluminium boards can eliminate the need for extra heat sinks or cooling fans. At Best Technology, we offer competitive pricing and help you optimize design for cost and performance.

What Is the Difference Between Aluminum PCB and FR-4?

The main difference between aluminum PCBs and FR-4 PCBs lies in the base material and how each board handles heat and mechanical stress.

Aluminum PCBs use a metal base (usually aluminum) that helps conduct heat away from components. This makes them a great choice for high-power circuits like LEDs and power supplies. In contrast, FR-4 PCBs are made from fiberglass material. They are versatile and cost-effective but have poor thermal conductivity, which can be a problem in heat-sensitive designs. Here’s a quick side-by-side comparison:

Feature	Aluminum PCB	FR-4 PCB
Base Material	Aluminum (metal core)	Fiberglass (FR-4)
Thermal Conductivity	High (1.0–3.0 W/m·K)	Low (~0.3 W/m·K)
Heat Dissipation	Excellent	Limited
Strength	Strong and durable	Moderate
Flexibility	Low (rigid)	Higher (can be rigid or flexible)
Cost	Slightly higher (for materials)	Lower for basic designs
Typical Use	LEDs, power electronics, automotive	Consumer electronics, general use

Use aluminium PCBs when your design needs to handle heat efficiently and survive tough environments. Use FR-4 when thermal demands are low, or you need flexible or multi-layer boards.

When to Use Aluminum PCB?

Aluminium PCBs are the right choice when you need:

Efficient heat dissipation
Reliable performance in high-power applications
Space-saving designs without extra heat sinks

Common applications include:

LED lighting systems (e.g., streetlights, automotive lamps)
Power converters and inverters
Battery chargers
Audio amplifiers
Telecom and base stations

If your design struggles with overheating or if your product needs to run 24/7 without failure, aluminium PCBs can help you achieve that.
