What is bendable aluminum substrate? Flexible Aluminum PCB

Friday, August 15th, 2025

Bendable aluminum substrate is a metal-based copper-clad laminate with folding or bending functions. It is bent and shaped through a special process. It has the advantages of good thermal conductivity, lightweight, and bending resistance. It is mainly used in the bendable structure of LED lamps and lightweight foldable components of electronic devices such as mobile phones.

What is bendable aluminum substrate? Flexible Aluminum PCB

Are you curious about:

What are the core advantages of bendable aluminum substrates?
How many bends can they last?
What is their heat dissipation performance?
What applications are they generally suitable for?

BEST Technology can provide you with high-performance bendable aluminum substrates. Our aluminum substrates offer the following properties:

High heat dissipation from the aluminum substrate combined with flexibility and bendability, ensuring both heat dissipation and surface adaptability.
Dynamic bending resistance of ≥80,000 times (R=1.5mm), ensuring continuous circuitry.
The aluminum substrate’s thermal conductivity and high adhesive layer provide a thermal resistance of ≤1.0°C/W, improving heat dissipation by 25% or more compared to ordinary flexible substrates.
LED flexible light strips, curved automotive lights, wearable devices, and other applications require both bending and heat dissipation.

What is flexible aluminum substrate?

Flexible aluminum substrate is a special type of circuit board base that uses bendable aluminum as its core layer. Unlike traditional rigid aluminum PCBs, these substrates are engineered to withstand controlled bending without cracking or losing structural integrity.

In PCB manufacturing, the substrate acts as the backbone. It supports copper traces, dissipates heat, and maintains mechanical stability. With bendable aluminum, you get all the advantages of aluminum’s high thermal conductivity and durability—plus the added ability to shape or curve the board during assembly or installation.

This property is particularly valuable in LED lighting strips, automotive electronics, aerospace control systems, and wearable devices. It allows products to fit into tighter spaces, wrap around surfaces, or follow curved housing designs without sacrificing performance.

What grades of bendable aluminum sheets are available?

Not all aluminum grades can be bent easily. The alloy composition and temper determine flexibility. Here are common grades relevant to PCB substrates:

1050 and 1100 Series

High-purity aluminum with excellent corrosion resistance.
Very good bendability, suitable for tight radius bends.
Often used for applications needing high ductility.

3003 Aluminum

Alloyed with manganese for better strength than 1100.
Maintains good bending properties.
Common in lighting and decorative PCB applications.

5052 Aluminum

Stronger than 3003, with excellent corrosion resistance.
Good formability, works well for medium bend radii.
Often selected for outdoor electronics or marine-grade designs.

6061 Aluminum

High strength but less ductile than 5xxx series.
Bendable in annealed tempers (O-temper) but more difficult in T6.
Ideal for structural applications where mechanical strength is critical.

6063 Aluminum

Good surface finish and corrosion resistance.
Easier to bend than 6061 in certain tempers.
Often used in heat sink-integrated boards.

Key takeaway: When choosing a grade, balance strength, bend radius, and thermal performance. In PCB manufacturing, 3003, 5052, and 6063 are common for bendable aluminum substrates.

How to test a bendable aluminum sheet?

Testing ensures the sheet meets your mechanical and thermal requirements before it becomes part of a PCB. Here are standard methods:

Bend Test: The sheet is bent to a specified radius and checked for cracks or surface deformation. For PCBs, smaller radii require more ductile alloys.

Elongation Test: Measures how much the aluminum can stretch before breaking. Higher elongation values mean better bendability.

Hardness Test: Indicates resistance to deformation. Softer aluminum generally bends more easily.

Thermal Cycling Test: Exposes the material to repeated heating and cooling to simulate operating conditions.

Surface Adhesion Test: Checks how well dielectric and copper layers adhere after bending.

These tests help engineers confirm that flexibility does not compromise thermal conductivity or copper adhesion.

How to make bendable aluminum substrate?

The process combines materials science and precision PCB manufacturing.

Select the Aluminum Core: Choose the alloy and thickness based on bending needs. Thinner cores bend more easily but handle less load.

Apply the Dielectric Layer: High thermal conductivity insulation is laminated onto the aluminum. Materials like polyimide or flexible epoxy composites are used.

Add Copper Foil: The copper layer is laminated and patterned through photolithography and etching.

Protect with Solder Mask: Flexible solder mask layer shields the copper and dielectric.

Final Forming: Boards may be partially formed before delivery, or bent during final assembly.

Special care is needed in temperature control, lamination pressure, and adhesive selection. Poor processing can cause delamination when bending, so experienced BEST Technology use advanced bonding techniques.

What are the benefits of bendable aluminum substrate?

The benefits go beyond just flexibility:

Superior Heat Dissipation: Aluminum’s high thermal conductivity allows efficient heat transfer away from heat-generating components.

Lightweight Strength: Maintains structural integrity even at reduced thickness.

Design Freedom: Enables curved or irregular shapes without multiple rigid sections.

Long Service Life: Resistant to corrosion, vibration, and impact.

Reduced Assembly Costs: A single bendable board can replace multiple interconnected rigid boards.

For manufacturers, this means better performance and simpler mechanical integration. For buyers, it means lower total cost and fewer failure points.

What are the applications of bendable aluminum substrate?

Applications span high-reliability and thermally demanding fields:

LED Lighting: Flexible mounting in architectural, automotive, and display lighting.

Automotive Electronics: Curved dashboard PCBs, lighting assemblies, and under-hood electronics.

Aerospace Systems: Weight-saving designs that fit tight spaces.

Wearable Medical Devices: Flexible yet robust circuits for monitoring and control.

Industrial Controls: Machines that require boards to wrap around mechanical housings.

In each case, the bendable aluminum substrate provides both mechanical adaptability and reliable heat management.

Does bending reduce the strength of aluminum substrate?

Yes, but the effect depends on alloy, temper, and bend radius. When aluminum is bent, it undergoes work hardening, which increases strength in the bend area but can also reduce ductility.

If bending exceeds the material’s formability limit, micro-cracks can form, reducing fatigue life. That’s why BEST Technology design for the proper bend radius based on alloy properties and thickness.

In practice, when using recommended bend parameters and high-quality processing, the strength loss is minimal for most PCB applications.

What Is a 4-Layer Rigid Flex PCB?

The 4-Layer rigid flex PCB is a composite board made by combining a flexible printed circuit board (FPC) and a rigid printed circuit board (PCB) through a special process, which has the characteristics of both. Its core structure usually includes a four-layer design, with the middle two layers being flexible areas and the two sides being rigid areas. The rigid-flex combination is achieved through a lamination process.

4 Layer Rigid Flex PCB Stackup

Layer 1 (Top): Rigid signal layer (routing + key components)
Layer 2 (Inner Layer 1): Flexible ground layer (PI substrate, providing shielding and mechanical support)
Layer 3 (Inner Layer 2): Flexible signal layer (low-speed/auxiliary signals, optimizing routing density)
Layer 4 (Bottom): Rigid power/ground plane (FR4, reducing noise coupling)

How thick is a 4-Layer Rigid Flex PCB?

A 4-layer rigid-flex PCB typically has a total thickness range of 0.8mm to 1.6mm, depending on the design requirements and material combinations. Rigid sections (FR4) usually measure 1.2mm thick, providing structural support. Flex sections (polyimide) are much thinner, commonly 0.1mm, allowing bending and flexibility. The overall thickness is influenced by the copper weight (e.g., 1oz for signal layers, 2oz for power/ground planes) and dielectric material (FR4 or prepreg) used in the stackup.

Why Use 4-Layer Rigid Flex PCB?

Advantages of 4-layer rigid flex PCB:

Space and Routing Optimization: A layered design separates signal and power planes, increasing wiring density and making it suitable for compact devices like smartphones.
Signal and Electromagnetic Performance: Adjacent power/ground layers reduce noise, and thick inner copper ensures stable high-speed signal transmission.
Efficient Thermal Management: The inner copper foil evenly dissipates heat, and thermal vias enhance reliability in high-temperature environments.
Mechanical and Durability: A rigid-flexible structure reduces bending failures, and a multi-layered, vibration-resistant design is suitable for industrial applications.
Design and Cost Balance: Customized stacking optimizes performance and cost, while eliminating cables and streamlining the assembly process.

When to Use 4 Layer Rigid Flex PCB?

Applications of 4 Layer Rigid Flex PCB:

High-Density Electronic Devices – Smartphones, tablets, and wearables requiring compact layouts with dynamic bending zones.
Automotive Electronics – Dashboard control units and sensors exposed to vibration and temperature fluctuations.
Medical Devices – Implantable monitors and portable diagnostics needing lightweight, biocompatible designs.
Aerospace Systems – Avionics and satellite components demanding weight reduction and shock resistance.
Industrial Robotics – Articulated arms with repeated motion joints requiring durable yet flexible interconnections.
Consumer Electronics – Foldable displays and rotating-camera mechanisms necessitating 3D PCB solutions.

How to Design a 4-Layer Rigid Flex PCB?

Here are 4-layer rigid flex PCB design guide:

1. Layer Stackup & Material Selection

Rigid Zones: Use FR4 substrate (1.6mm thickness) for structural integrity.
Flex Zones: Opt for polyimide substrates (e.g., DuPont Pyralux AP/LF/FR) with 0.1–0.3mm thickness to accommodate dynamic bending.
Copper Type: Rolled Annealed (RA) copper for flex layers to ensure ≥100,000 bend cycles.
Coverlay: Match coverlay thickness to copper weight (0.5oz Cu → 1mil coverlay; 1oz Cu → 1.5mil coverlay).

2. Bend Radius Calculation

Formula: Minimum bend radius R=t×K, where t = total flex-zone thickness, K = layer-dependent coefficient (single-layer K=6–10; dual-layer K=10–15; four-layer K=20–50).
Example: For a 0.29mm four-layer flex zone, dynamic bend radius must be ≥5.8mm to prevent copper cracking.

3. Routing & Impedance Control

Signal Layer Allocation: Place high-speed signals (e.g., DDR, PCIe) on outer layers (L1/L4); use inner layers (L2/L3) for power/ground planes.
Trace Rules: Follow IPC-2223 standards (e.g., 70µm trace width/90µm spacing for 0.5mm BGA).
Microvias: Use laser-drilled microvias (≤0.1mm diameter) with copper-filled construction (IPC-4761 Type VII).

4. Mechanical & Thermal Design

Transition Zones: Implement “key-and-slot” designs or plastic frames to reduce stress concentration at rigid-flex junctions.
Thermal Management: Use ≥1oz copper in power/ground planes; add thermal via arrays (spacing ≤1mm) for heat dissipation.
Component Reinforcement: Add stiffeners (Kapton or aluminum, <10mil thickness) under flex-zone components to mitigate soldering stress.

5. Manufacturing & Testing Standards

IPC Compliance: Meet IPC-6013 Class 3/A requirements via 100% electrical testing, AOI, and X-ray inspection.
Reliability Tests: Conduct thermal shock (-40°C to 125°C), vibration (≥20G random), and bend cycle (≥1000 iterations) validations.

What is Rigid-Flex Copper Substrate? Rigid Flex PCB

Thursday, August 14th, 2025

Rigid-flex copper substrate combines the best of both rigid PCBs and flexible circuits into a single circuit board. This design is both practical and innovative. Its applications range from advanced medical devices to aerospace systems. Its versatility stems from the way its copper layer is integrated with both flexible and rigid components, enabling smooth folding without disrupting connections.

What is Rigid-Flex Copper Substrate? Rigid Flex PCB

Do you want to know:

What are its advantages over ordinary substrates?
How many frequent bends can it withstand?
How is heat dissipation guaranteed?
Does it support complex circuits and unusual shapes?
What is the prototype production cycle?
What are the quality standards?

BEST Technology, a professional metal-based circuit board manufacturer, can answer your questions:

The high heat dissipation of a rigid substrate combined with the flexibility of a flexible substrate allows for complex applications.
Dynamic bending resistance of ≥100,000 times (R=1mm) ensures continuous circuitry and stable performance.
Highly conductive adhesive layer combined with a full copper surface design results in a thermal resistance of ≤0.8°C/W, improving heat dissipation by 30%+ in high-temperature environments.
Minimum line width/spacing of 3 mils, supports unusual shapes and stepped structures, and an accuracy error of ≤±0.1 mil.
Prototypes take 3 days, and mass production takes 7-15 days. Compliant with IPC-A-600H, with over 20 tests and 24-hour customer service.

What is rigid-flex copper substrate?

Rigid-flex copper substrate is a hybrid printed circuit board that has rigid and flexible layers combined into one structure. The rigid parts provide mechanical stability, while the flexible layers connect them, allowing bending or folding during assembly or use.

This combination removes the need for connectors or separate ribbon cables, reducing the risk of signal loss or failure. In many designs, rigid-flex boards improve reliability and performance at the same time.

The rigid flex PCB design typically uses copper foil as the conductor. Copper is preferred because it offers excellent conductivity, mechanical strength, and resistance to fatigue. The result is a board that can bend without losing electrical integrity.

Rigid-flex copper substrate with different layers

Layer count in a rigid-flex board greatly impacts performance, cost, and applications.

1. 2-layer rigid-flex copper substrate

This is the simplest form. It offers enough flexibility for basic designs and is often used in consumer devices, portable gadgets, and small control panels. It’s affordable and fast to produce.

2. Dual-layer rigid-flex copper substrate

Similar to the 2-layer version but often built with reinforced materials. It provides more strength and is ideal for designs that require slight bending during use.

3. 4-layer rigid-flex copper substrate

With more copper layers, it allows complex routing, better signal performance, and improved EMI shielding. The 4-layer copper-based rigid-flex PCB is common in automotive electronics and handheld medical devices.

4. 6-layer rigid-flex copper substrate

This high-end design is built for advanced technology. It supports multiple high-speed signals, complex interconnections, and precise impedance control. Aerospace systems, industrial control machines, and military electronics often use this type.

Choosing the right layer count depends on design needs, available space, and budget. Each option balances performance and flexibility differently.

How does rigid flex PCB work?

The rigid flex PCB works by integrating multiple circuit layers—some rigid, some flexible—into one laminated structure. During manufacturing, the flexible layers are bonded with polyimide material, while the rigid parts are reinforced with FR4 or other stiffeners.

When installed, the flexible sections bend to fit inside tight enclosures. This makes it perfect for 3D assembly. The electrical signals flow through copper traces that remain continuous across the rigid and flexible areas, eliminating the need for connectors.

By reducing interconnections, rigid flex PCBs lower the risk of mechanical failure, improve signal speed, and make products more reliable in harsh conditions.

Why choose rigid-flex copper substrate?

There are many reasons to choose a rigid-flex copper substrate.

Space efficiency: This design allows components to be placed closer together, reducing product size.

Durability: Flexible sections handle repeated bending without breaking. This is important in devices exposed to motion or vibration.

Improved performance: Fewer connectors mean faster signal transmission and less interference.

Lightweight construction: Replacing multiple boards and cables with one unit cuts down weight.

Design freedom: Three-dimensional design is possible, allowing for better utilization of interior space.

From smartphones to satellites, rigid-flex boards help achieve higher performance without increasing size.

Which flexible PCB material is best?

The performance of a rigid-flex PCB depends heavily on the flexible material. Most use flexible circuit technologies with polyimide films, which offer excellent heat resistance, flexibility, and electrical insulation.

Polyimide is also stable in harsh environments, making it a trusted choice for aerospace, automotive, and industrial applications. For added strength, some designs use adhesive-less laminates, which improve bending capability and reduce thickness.

Copper foil is the heart of the conductor. Rolled annealed copper is preferred for its flexibility and fatigue resistance, while electro-deposited copper works well for more rigid applications.

The choice of flexible PCB material depends on the final product’s environment, electrical needs, and mechanical requirements.

How durable is flexible PCB material?

Flexible PCB materials are surprisingly tough. High-quality polyimide can handle thousands of flex cycles without cracking. Even in high-temperature or high-vibration environments, it maintains structural integrity.

Durability also depends on copper type, layer thickness, and protective coatings. Protective coverlays shield copper traces from moisture, dust, and abrasion. When designed correctly, a rigid-flex PCB can last as long as the device itself.

It’s worth noting that durability is not just about materials—it’s also about design. Proper bend radius, trace routing, and reinforcement all increase lifespan.

How does rigid flex PCB save space?

One of the biggest advantages of rigid-flex PCBs is their space-saving ability. By combining rigid and flexible sections into one board, you remove the need for bulky connectors and cables.

This allows components to be stacked closer or arranged in creative ways. Devices can be slimmer, lighter, and easier to assemble. For example, in wearables or medical implants, every millimeter counts. The space saved often translates directly into more battery capacity, extra features, or lighter designs.

For manufacturers, fewer components mean faster assembly and fewer points of failure.

What affects rigid-flex copper substrate cost?

Cost can vary widely depending on several factors:

Layer count: More layers mean more complex manufacturing, which increases price.

Material choice: Premium copper foils and polyimide films cost more but offer better performance.

Size and shape: Complex shapes require more precise processing.

Production volume: Higher quantities often reduce per-unit cost.

Testing requirements: Rigid-flex boards for aerospace or medical devices require strict quality control, adding to cost.

Working with a skilled flex PCB manufacturer ensures cost efficiency without compromising quality. BEST Technology will help you choose the best PCB stackup, optimize the number of layers, and select the most suitable flexible PCB material for your needs.

What is UAV aluminum substrate? UAV materials

Wednesday, August 13th, 2025

UAV aluminum substrate is a lightweight circuit board composed of a high-thermal-conductivity aluminum alloy substrate, copper-clad circuitry, and an insulating dielectric layer. It can rapidly dissipate heat from flight control chips and power devices with a thermal conductivity exceeding 1.5 W/m·K. It is 30% lighter than traditional FR-4 boards and is resistant to 20g vibration and temperature fluctuations from -40°C to 85°C, providing reliable heat dissipation and structural support for the high power density and long flight time requirements of UAVs.

What is UAV aluminum substrate? UAV materials

Are you concerned about the following issues when using aluminum substrates in UAVs?

UAVs are weight-sensitive. Will aluminum substrates be too heavy?

The motors/power modules generate a lot of heat; can they keep up with the heat dissipation?

Will the substrate be easily damaged by the high vibration and impact during flight?

Is bulk purchasing expensive? Can custom sizes be made?

Is it environmentally compliant? Is it easy to recycle?

At BEST Technology, we can easily address your concerns:

We use high-purity, lightweight aluminum with a density of only 2.7g/cm³, 65% lighter than traditional steel substrates. This balance of strength and weight reduction makes it perfectly suited to UAV endurance requirements.

The aluminum substrate has a thermal conductivity of 1-3 W/(m·K), 3-10 times that of ordinary FR4 substrates. The insulation layer is made of a highly thermally conductive epoxy resin, allowing heat to be transferred directly to the aluminum substrate and quickly dissipated, preventing component overheating and failure.

The aluminum substrate provides high mechanical strength, resistance to bending and vibration, and, combined with a specialized insulation layer process, ensures stable circuit connections under complex operating conditions, with a failure rate below 0.5%.

Standardized production reduces costs, with prices as low as one-third those of ceramic substrates. Customization is available in thicknesses from 0.3-3mm and any size, with rapid 7-day proofing and short lead times for mass production.

The entire process is RoHS/WEEE compliant, the aluminum is 100% recyclable, and processing produces no toxic emissions, ensuring regulatory compliance while contributing to sustainable development.

What is the aluminum substrate definition in PCB manufacturing?

In printed circuit board (PCB) manufacturing, an aluminum substrate refers to a PCB base material where a layer of aluminum replaces the conventional fiberglass or epoxy base. This type of substrate uses aluminum as the core to provide high thermal conductivity, excellent mechanical stability, and improved heat dissipation.

It is often called an aluminum substrate PCB or metal-based PCB. The aluminum core is laminated with an insulating dielectric layer and a copper circuit layer on top.

In UAV (unmanned aerial vehicle) applications, aluminum substrates have gained recognition for their ability to handle high thermal loads from compact electronic systems. These substrates offer a balanced combination of electrical performance and mechanical durability, which is essential in airborne environments.

Why are aluminum substrates ideal for UAV materials?

UAVs require lightweight, strong, and thermally efficient materials. Aluminum substrates check all these boxes.

First, aluminum has an excellent strength-to-weight ratio. This allows UAV designers to reduce overall weight while maintaining durability.

Second, UAV electronics generate heat during operation, especially in high-performance drones used for mapping, surveillance, or industrial inspections. Aluminum substrates dissipate this heat faster than traditional materials. This protects sensitive components from overheating, extending operational life and maintaining stable performance.

Third, aluminum resists corrosion when treated with protective coatings, which is important for UAVs that operate in various weather conditions.

What are the characteristics of a UAV aluminum substrate?

UAV aluminum substrates offer numerous advantages and are widely used in UAV applications.

Excellent heat dissipation: Aluminum has a high thermal conductivity, and aluminum substrates incorporate a built-in metal “heat dissipation layer.” This thermal conductivity is typically 1-3 W/(m・K), 3-10 times that of standard FR4 substrates (0.3 W/(m・K)). This allows for rapid heat dissipation from high-power components in UAVs, such as motor drive modules and batteries, preventing component degradation or damage due to overheating and extending the lifespan of the device.

Lightweight: Aluminum has a low density of only 2.7 g/cm³, making it 65% lighter than steel for the same size. Using aluminum substrates can effectively reduce the overall weight of a UAV, significantly improving its flight range, flight maneuverability, and payload capacity. Aluminum substrates are particularly suitable for weight-sensitive lightweight UAVs and FPV racing UAVs.

High Mechanical Strength: The aluminum layer imparts high mechanical strength and strong bending resistance to the substrate. During UAV flight, it can withstand certain vibrations and shocks without deformation or damage, ensuring stable connections between components on the circuit board and enhancing the UAV’s reliability and durability.

Excellent Electromagnetic Shielding: The aluminum layer absorbs and shields electromagnetic interference, reducing signal crosstalk between circuits and improving the UAV’s circuit system’s anti-interference capabilities. This ensures stable transmission of flight control and communication signals, enabling the UAV to operate normally even in complex electromagnetic environments.

Manageable Costs: Compared to some high-performance but expensive substrate materials, such as ceramic substrates, aluminum substrates are more affordable. The processing technology is similar to that of ordinary PCBs, making them suitable for large-scale production. This ensures UAV performance while effectively controlling production costs.

Environmentally Friendly and Energy-Saving: Aluminum is 100% recyclable, and the processing process produces no toxic substances, complying with environmental regulations (RoHS/WEEE) and contributing to sustainable development.

What is the structure of a UAV aluminum substrate?

UAV aluminum substrate consists primarily of three layers: a metal aluminum base layer, an insulating layer, and a conductive layer.

The metal aluminum base layer is the main component of the substrate, providing excellent thermal conductivity and mechanical support. The insulating layer, typically made of materials such as epoxy resin and ceramic, separates the conductive layer from the aluminum base layer, ensuring electrical insulation. The conductive layer, typically made of copper foil, provides circuit connections and signal transmission.

What is the principle behind a UAV aluminum substrate?

When a UAV is operating, the components in the circuit generate heat. This heat is first transferred to the copper foil of the conductive layer, then conducted through the insulating layer to the aluminum substrate, where it is finally dissipated into the surrounding environment.

In this way, the aluminum substrate effectively conducts heat away from the heat-generating components, achieving heat dissipation and ensuring stable operation of the UAV circuit system.

How is an aluminum substrate PCB made for UAV applications?

Manufacturing a UAV aluminum substrate PCB involves several precise steps:

Material preparation: The aluminum base is cut and cleaned to remove impurities.

Dielectric layer lamination: A thermally conductive yet electrically insulating layer is applied over the aluminum.

Copper foil bonding: Copper is laminated on top of the dielectric layer.

Circuit patterning: Photolithography and etching are used to create the desired circuit paths.

Surface treatment: Protective coatings like HASL, ENIG, or OSP are applied to enhance solderability and prevent oxidation.

Drilling and routing: Holes for components and mounting points are drilled, followed by final shaping.

Inspection and testing: The PCB undergoes thermal, electrical, and mechanical testing to ensure it meets UAV performance standards.

These steps require tight quality control because UAV applications demand both high reliability and precise tolerances.

How does an aluminum substrate PCB improve UAV performance?

Aluminum substrate PCBs enhance UAV performance in several ways:

Heat management: Efficient thermal dissipation keeps electronics cool, ensuring stable flight operations even in hot climates.

Weight Optimization: By using aluminum, weight can be reduced without sacrificing strength, thereby extending flight time.

Reliability in harsh conditions: The aluminum core withstands vibration, temperature swings, and mechanical shocks better than standard FR4 boards.

Compact design: With built-in heat dissipation, there’s less need for large cooling systems, freeing up space for sensors or payload.

Energy efficiency: Stable operating temperatures reduce energy loss in electronics, indirectly improving battery efficiency.

The result is a UAV that performs better, lasts longer, and remains reliable across diverse missions.

What are the applications of a UAV aluminum substrate?

UAV motor driver module: UAV motors generate significant heat during operation. The excellent heat dissipation performance of aluminum substrates ensures that components such as the motor driver chip operate within a normal temperature range, improving motor efficiency and reliability while also extending the lifespan of the motor and driver module.

FPV racing UAVs: FPV racing UAVs have extremely high weight and performance requirements. Aluminum substrates can reduce weight while meeting the heat dissipation requirements of high-speed flight and high-load operation, helping to improve flight speed and controllability.

UAV power systems: These include battery management circuits, power conversion modules, and other components. These components also generate significant heat during operation. Using aluminum substrates effectively dissipates heat, ensuring stable output from the power system and improving the UAV’s flight endurance and overall performance.

Conclusion:

UAV aluminum substrates combine the strengths of aluminum with the precision of PCB manufacturing. Whether in photography, industrial inspection, or military use, these substrates provide a dependable foundation for advanced electronics.

Outstanding Quality True Double Sided Aluminum PCB

Wednesday, August 13th, 2025

True double sided aluminum PCB takes center stage in some applications request compact size, high heat dissipation performance, and high flexibility routing. In this blog, we will tell you about the definition, price, manufacturing process, and benefits of a true double sided aluminum PCB.

Are you worried about these issues when doing the project of a true double sided aluminum PCB?

Geometric accuracy challenge?
High manufacturing difficulty and cost?
The thermal management and the heat dissipation issues?
The poor reliability and the longevity?

Best Technology tackles the above challenges through our fruitful experience.

Optimizing the manufacturing process and tool path design: For example, we make use of the DSIF strategy and simultaneous machining on both sides to reduce deformation and stress caused by the single-sided manufacturing.
Material selection and heat treatment process: We will select the high-purity aluminum material, such as 6061 or 7075 aluminum alloy, since it has excellent thermal conductivity and mechanical performance. Meanwhile, we will utilize the heat treatment process to improve the material strength and stability.
Multi-layer structure design and the connection technology: We will exploit the reliable connection technology to improve the connection strength between layers and the reliability when using the multi-layer structure designs. Meanwhile, we will apply the multi-layer insulation to improve the insulation performance and thermal stability.
Heat management and the heat dissipation design: We will integrate thermal dissipation structure into the aluminum substrate boards, so as to improve the thermal dissipation efficiency. In the meantime, we will take the low thermal resistance materials and the thermal interface material to improve the heat conductivity efficiency.
Reliability test and the longevity evaluation: We will evaluate the long-term reliability of the aluminum substrate board through accelerated longevity testing, thermal cycle inspection, mechanical fatigue tests, and others. We use the cutting-edge reliability analysis tool for prediction and optimization.

What is a True Double Sided Aluminum PCB?

A True Double sided aluminum PCB is a metal-core printed circuit board with copper layers on both sides of an aluminum core. It supports the double sided electrical connection compared to the traditional single sided MCPCB. And it can finish more complex circuit design in a limited board surface, and keep the outstanding quality heat dissipation as well. It is widely used in LED systems, power modules, and high-performance automotive electronics.

What is the difference: True Double Sided Aluminum PCB, Pseudo Double Sided Aluminum PCB?

The point is that there is a significant difference in the way of interconnection between layers. A true double sided aluminum PCB uses plated through-holes to connect the top and bottom copper layers directly. Whereas, a pseudo double sided aluminum PCB generally does not get the electrical connection, although both sides have copper. It is necessary to get the connection via a mechanical way or external jumpers. It is worthwhile to note that a true double sided aluminum PCB can realize more compact and reliable layouts.

What is the Difference between 2 Layer MCPCB and a Double Sided Aluminium PCB?

A 2 layer MCPCB generally refers to two copper layers separated by a dielectric layer over an aluminum base. And its layers can make the electrical connection via a plated through hole. The key is that a double sided aluminium PCB does not have the double sided copper layers in physics. It not only has copper on both sides but also reduces the usage needs of the extra components via direct interconnection between layers. Moreover, it improves the layout efficiency and the integration.

To sum up, both types of boards can improve the routing efficiency‌ and integration level‌. But the double sided aluminium PCB is more suitable for the thermally demanding environment for its aluminium base features.

What are the Two Sides of an Aluminium PCB Called?

The two sides are typically called the top copper layer and the bottom copper layer. In a true double sided aluminum PCB, both sides are functional for routing and component placement. And it provides more flexibility in design for the compact equipment.

What is the True Double Sided Aluminum PCB Price?

The true double sided aluminum PCB price is fluctuated by a variety of factors, including material thickness, copper foil weight, hole plating quality, and the manufacturing batch quantity, among others. It significantly reduces the whole project costs via reducing assembly time, improving the PCB longevity, and other aspects, although in the initial stage, the price may be higher than the single sided MCPCB.

When will PCB Double Sided Tape be Used?

PCB double sided tape is used in cases where components or heat sinks need secure attachment without drilling holes. For example, it is generally used in fixing the LED or secondary small boards on the aluminum PCB, especially in the prototyping stage. PCB double sided tap not only provides stable mechanical stability but also avoids the extra steps. Finally, pls pay attention that the specific application may be different for its types, such as the PE foam tape, and the substrate characteristics, such as metal core PCB or glass.

How to Make a Double Sided Aluminium PCB?

Start with the aluminum core board, which has premium mechanical strength and outstanding thermal dissipation performance.
Laminate a thin dielectric layer on both sides of the aluminum core. That layer not only guarantees the electrical insulation but also conducts heat more efficiently.
Bond copper foil layers onto the dielectric layers on both sides. These copper foils will carry the circuit traces.
Apply photoresist and use a photolithography process to define the precise circuit patterns on both copper sides.
Etching away the extra copper and saving the designed routing only.
Drill plated through-holes (PTH) through the board to connect the copper layers on both sides electrically. This involves precise hole drilling and copper plating inside the holes.
Making the copper plated to the exposed circuit pad and the through holes, to ensure a stable connection and the ease of soldering.
Making the solder paste layer on both sides to protect against oxidation and the short circuit of circuits. Finally, improve the assembly safety.
This step is the surface treatments, such as HASL, ENIG, and others, which improve the soldering quality and reliability.
This next step is doing the inspection and testing strictly, to guarantee the PCBs are in line with technical requirements. We need to double-check the alignment accuracy between layers, through-hole quality, and heat dissipation performance.
Finally, clean and prepare the boards for shipment or assembly into devices.

Why Use a True Double Sided Aluminum PCB?

The major point to choose this board is for the high thermal dissipation performance, the board size reduction, high flexibility of routing, and stability consistency in the high current designs. For issues such as thermal dissipation shortage and routing limitations, true double-sided aluminum PCBs are stable and reliable solutions.
