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.

What is a Robotic Aluminum Substrate PCB?

It is valuable to note that a robotic aluminum substrate PCB is an aluminum substrate printed circuit board, designed for robot system optimization that requires high thermal conductivity, excellent mechanical strength, and stable performance under dynamic loads. Its core feature is that it achieves heat dissipation effectively and a mechanical strength balance via the aluminum core substrate layer.

First, it has three compound structures, such as the circuit layer, insulated layer, and the aluminum core substrate layer. Moreover, it achieves the conductivity of the layers via an insulated resin filling.
Second, it is vital to note that the robotic aluminum substrate PCB has excellent heat management capability. Compared to the FR-4 substrates, aluminum PCBs can reduce power device temperature rise by 40-60%. Besides, it has nice mechanical adaptation. Its flexibility is 8-10 times that of the ceramic substrate.
Finally, it is worth mentioning its wide application, such as the servo drive system, joint control module, and environmental sensing unit.

What is a Robotic Aluminum Substrate PCB?

What are the Features of the Robotic Aluminum Substrate PCB?

The features of a robotic aluminum substrate PCB are tailored to meet the unique demands of robotics applications:

High thermal conductivity — vital for high-power components and LED modules.
Mechanical strength — handles vibration and shock without delamination.
Application adaptation — It is specifically designed to tackle the robot core components optimization of the servo drive system, joint control module, and environmental sensing unit.
Environment Stability — Its withstand voltage of the insulated layer is more than 3000V. Besides, it can keep dielectric stability under a humidity rate 85%.
Customizable layer stack-up — supports single-layer or multi-layer designs based on complexity.

What are the Features of the Robotic Aluminum Substrate PCB?

What is the Robotic Aluminum Substrate PCB Price?

The price of a robotic aluminum substrate PCB depends on several factors:

Base material grade — higher conductivity aluminum costs more but offers superior performance.
Board size and thickness — larger or thicker boards require more raw material.
Layer count — multi-layer designs increase manufacturing complexity.
Surface finish type — ENIG, HASL, and other finishes have different costs.
Order volume — higher quantities often lead to lower per-unit pricing.

There is no MOQ requirement in Best Technology. We produce the order quantity from robotics PCB design, prototype, mass production, and mid-volume robotics PCB assembly to high-volume robotics PCB assembly. We have the integrated production and SMT lines, which help to shorten the delivery time significantly without risking the quality.

What are the Major Considerations in Robotics PCB Design?

It is good to note that the major considerations in robotics PCB design include four aspects.

The first factor is the signal completeness optimization. It is necessary to plan the route line to design the low impedance return current path, so as to reduce the EMI radiation. Since gaps in ground planes force return currents of microstrip lines to detour.
The second critical factor is the mechanical reliability design. High-density via areas require via-in-pad or back-drilling processes to reduce the risk of solder joint fatigue caused by the CTE mismatch.
The third important factor is the environmental adaptation. It is essential to take the conformal coating for the surface or making the micro-arc oxidation treatment.
The final vital point is the manufacturability balance. The double-sided board can take the 5-layer structure: copper foil, aluminum substrate, insulation, copper foil, so as to balance the complexity and the costs.

How to Ensure the Quality During the Robot PCB Assembly?

It is required to take the following major measures to ensure the robot PCB assembly.

First, the high-frequency signal lines require impedance-matching design, such as equal-length routing for differential pairs.
Second, the major connection position uses the high-reliability solder material, such as SAC305 alloy.
Third, it is vital to control the process and do the inspection. It is critical to use the AOI and X-ray to inspect the soldering quality. And it needs to control the size tolerance with 0.8mm and the assembly tolerance with 1.5mm, so as to reduce the rate of defects. And the industrial robot needs to do the tests, including vibration, temperature, and humidity cycle, etc.
Finally, it is better to do the DFM analysis during the design phase to avoid the process conflicts.

How to Achieve Fast Delivery for Robotic Aluminum PCBs?

Metal core manufacturers maintain the consistency of fast delivery, which means a lot to the customers. And here’s how it’s done:

Material readiness — keeping high-demand aluminum substrates in stock eliminates waiting for raw material procurement.
Concurrent engineering — design and manufacturing teams work together to spot issues before production starts.

If 8W specifically refers to the copper foil thickness of 8oz, which is in the category of heavy copper PCB. If the PCB applies the aluminum substrate and the copper foil thickness up to 8W, which is a special type of heavy copper aluminum PCB. This board features include high thermal conductivity and high current-carrying capacity. These are great for some thermal management applications, but heavy copper PCBs excel in high-current environments found in many automotive power electronics. It is useful to note that if the sectional structure is a pure copper substrate, such as the copper clad laminate or aluminum substrate compound board.

So, Automotive Copper Substrate PCB 8W primarily implies a heavy copper PCB designed to meet rigorous automotive standards, rather than an aluminium core PCB.

Does Automotive Copper Substrate PCB 8W Mean Heavy Copper PCB or Aluminium Core PCB?

What is the Automotive Copper Substrate PCB 8W Price?

Now, let’s discuss what factors will impact the automotive copper substrate PCB 8W price. Let’s take the MCPCB type as an example.

First, the material and process cost plays an essential role. The metal core PCB, such as copper clad laminate, has the thermal conductivity of up to 8W/(m·K), which is higher than the common FR-4 PCB board price. Besides, the circuit finness, such as 25/25μm line width and the line distance, and the layers, such as the single layer, double layer, will impact the manufacturing costs significantly.
Another fundamental role is the application difference. The Copper-based heat sink between the automobile high-power LED lighting board and the radar/BMS PCB exists a difference. Moreover, the rigid board and the flexible board quotes are having up to 30%-50% gap.

The final crucial factor is the marketing fluctuation and the customization. The growth rate is about 15.6% for the automobile electronic PCB market in 2025. It is important to note that bulk purchasing can lower the unit price further.

If you want to know more information about the automotive copper substrate PCB 8W price, it would be greatly appreciated if you provide the specific parameters, such as size, copper thickness, and the heat dissipation requirements. So that we could quote you the exact price.

What is the Difference Between 5 Layer PCB Stackup and 8-Layer PCB Stackup Example?

It is significant to note that the core difference between a 5-layer PCB stackup and an 8-layer PCB stackup lies in the layers, signal completeness, and the power allocation strategy.

First, the difference in layer structure. A 5-layer PCB stackup commonly applies 3 signal layers, 1 power plane, and 1 ground plane design. It is necessary to use adjacent signal layers sharing a reference plane to realize impedance control. However, an 8-layer PCB stackup is mainly 4 signal layers, 2 power planes, and 2 ground planes, like signal1/ground1/signal2/power1/ground2/signal3/power2/signal4. Pls note that every signal layer has an independent reference plane.

Second, the signal completeness performance. The intermediate signal layer of a 5-layer board is easily disturbed by the adjacent signal layer. And it achieves the low-loss microstrip propagation through the surface layer only. However, the 8-layer board is a through structure like signal2/ground2/signal3, to form two optimal stripline routing layers. The disturbance rate is lower than 40dB above.

Third, the power system design. The 5-layer board is difficult to support several voltage pressure areas with the power plane only. Since the power impedance is higher. but the 8-layer double power layer can achieve zoned power distribution with 20μm heavy copper. The immediate current load is improved by 66%.

Finally, the EMI shielded capability. A 5-layer board is only 1 complete ground plane. The high-frequency radium is weak. Whereas the 8-layer has a 3-ground plane design, such as ground1/power1/ground, which achieves the Faraday cage effect, enhancing geomagnetic absorption capacity by 300%. The extra layers in an 8-layer PCB enable better control of electromagnetic interference (EMI) and allow for higher-speed signal routing. For automotive copper substrate PCB 8W designs, this is often essential to manage heat and power delivery in high-performance modules.

How to Choose the PCB Material for High Temperature?

Common choices for automotive copper substrate PCB 8W include heavy copper substrates paired with advanced epoxy or ceramic-based laminates. It is interesting to know how to choose the PCB material for high temperatures. Here, I will take the automotive copper substrate PCB 8W as a case. There are 3 aspects we would like to discuss.

The first basic role is the heat conductivity coefficient requirement. The automotive copper substrate PCB 8W should choose the dielectric layer material whose heat conductivity coefficient is over 3.0W/mK. And it is critical to note that the heat conductivity coefficient could be up to 200W/mK if using the ceramic(like AIN) to fill the aluminum substrate board. And the copper layer thickness is recommended to be over 2oz, which, if working together with over 1.5mm aluminum substrate, will achieve the heat dissipation effectively.

The second factor is the heat-resistance grade match. If in the engine compartment environment, the long-term operation temperature of the board’s material needs to be over 150℃， and the short-term operation temperature should be up to 300℃ (such as the urgent speed work situation)

Finally, the main factors are vibration reliability and electrical insulation assurance. First, the material should pass the reliability test at random, such as the 20G mechanical shock test and the 10-2000Hz random vibration verification. Second, to ensure the electrical insulation, we recommend using the UL94V-0 flame-retardant grade materials.

Where is Automotive Copper Substrate PCB 8W Used?

Automotive Copper Substrate PCB 8W finds applications across various automotive sectors, particularly in power electronics and thermal management areas:

Battery management system (BMS): This is an innovative application. In the electrical car batteries, an 8W copper substrate PCB is used to get the modules of the current sensor circuit. It is noted that the premium copper electrical conductivity ensures the sampling precision.

How to Choose the Copper Clad PCB Board for MCPCB Design?

Monday, August 11th, 2025

It would be great if you could give us your specific requirement via sales@bestpcbs.com. We are more than happy to give you our full service from metal core PCB prototype to final delivery.

What is a Copper Clad PCB Board?

A copper clad PCB board refers to a substrate material laminated with a thin layer of copper foil on its surface. Typically, it consists of an insulating substrate such as FR-4, bonded with copper foil through a lamination process.

Copper clad materials can be broadly categorized based on their substrate type:

If the substrate is metallic, such as aluminum or copper, it forms a Metal Core PCB (MCPCB). These PCBs are designed for applications with high thermal demands, where effective heat dissipation is crucial.
If the substrate is non-metallic, like FR-4 fiberglass, it is known as Copper Clad Laminate (CCL), widely used in general electronic circuit boards.

Depending on the specific application, PCB cores can vary from FR-4 fiberglass, metal cores (aluminum, copper), to advanced ceramic substrates. In this discussion, the focus will be on metal core PCBs.

What Does Copper Clad Laminate Mean?

Copper clad laminate is also called CCL, which refers to the raw material. But copper clad PCB board may include the finished PCBs. Copper clad laminate is an essential and basic material in electronic manufacturing, like phones and laptops. That features the circuit conducting in electronic parts. The structure of copper clad laminate is hot-pressed by copper foil, an insulated substrate, such as Resin and glass fiber. It consists of a core insulating material bonded with copper foil on one or both sides.

Difference Between Copper Clad PCB and Photosensitive Copper Clad Board

While a copper clad PCB board is a general base for PCB fabrication, a photosensitive copper clad board has a special coating that reacts to light exposure. It has a great feature that it can form the circuit pattern through exposure and development. No need to process the traditional etching process to form the circuit pattern.

However, the big difference between copper clad PCB and photosensitive copper clad board is that the copper clad PCB should undergo etching, drilling, and other complex processes, then finish the PCB. It is commonly used in consumer electronics and communication devices. So the photosensitive copper clad board simplifies the manufacturing process, and it is mostly perfect for the small batch and the high precision circuit manufacturing, like HDI PCB board.

What is the Copper Clad PCB Board Price?

There are mainly 3 factors for price fluctuation.

The first factor is the substrate type, such as aluminum core and copper core. The aluminum core price is generally higher 30%-50% than the common FR4. However, the copper core substrate board will be more expensive, whose unit price may increase 50%-100% than the aluminum core board, which depends on the copper purity and the copper thickness.

Another factor is the complexity of the manufacturing process. The cost will increase 15%-25% if the high thermal metal core board needs special hole drilling, such as laser drilling, and surface treatment, such as immersion gold. Since this process is more complex, it is difficult to do well.

The final factor is the manufacturing batch quantity. If the quantity is lower than 100 pieces, the prototype unit price may be USD20-50 per piece. However, if above 1000 pieces, the price could be lower to USD5-10 per piece. And the copper core board will increase the cost by more than 20%-30%.

What is the Copper Clad PCB Board Price?

Layers of Copper Clad Board Double Sided

A double sided copper clad board has three material layers: copper foil on the top, insulating substrate in the middle, and copper foil at the bottom. A double sided copper clad board means there are laminated with copper foil on both substrate sides. That is suitable for the electronic equipment that needs both sides to have the circuits. It is applicable for medium complexity circuit design.

Double sided circuits are making the electricity connection through vias. The standard layer of double-sided copper-clad board is only 2 layer copper foil, which is a double-layer routing layer, without an inner layer of copper foil. If the double-sided copper-clad board has an inner layer, it needs to be specified like this: 4-layer copper clad board, which has 2 inner layers.

Manufacturing Process of Single Sided Copper Clad PCB Board

Manufacturing a single sided copper clad board involves several steps:

Material Preparation: Cutting copper clad laminate to required size.
Cleaning: Removing contaminants for better adhesion.
Pattern Transfer: Applying a resist to define circuit patterns.
Etching: Removing unwanted copper to reveal conductive traces.
Finishing: Applying surface finishes for solderability and corrosion protection.

This straightforward process makes single sided copper clad boards a cost-effective choice for simpler MCPCB designs.

Difference Between Copper Clad PCB Board, Copper Plated PCB Board, and Copper Coated PCB Board

These terms sound similar but have distinct meanings.

A copper clad PCB board refers to the base material with copper laminated on one or both sides.

A copper plated PCB board describes a board that has undergone plating during manufacturing, such as adding copper to through-hole walls.

Copper coated PCB board is a non-standard term, sometimes used to mean boards with a copper surface layer, but it lacks precision in professional contexts.

How to Choose the Copper Clad PCB Board for MCPCB Design?

Choosing a suitable copper clad PCB board for MCPCB design involves 6 fundamental factors.

First, you should choose suitable copper foils. There are ECF, RACF, and special copper foil for your selection. The ECF is suitable for the low frequency and the high current applications, which have low cost, but it’s mechanical strength is up to 150-300MPa. But its surface roughness is Ra 0.8-1.2μm, which may cause the high-frequency signal loss. The RACF is a great option for high-frequency transmission or the flexible MCPCB design. This copper foil has excellent ductility, and the surface is smoother. The third foil is a special type, like the high thermal copper foil or the copper foil, where Rz is lower than 3μm. It is suitable for high-power heat dissipation or high-speed circuits.

The second factor is copper thickness and the heat dissipation design. The outer layer commonly used is the 1/2 ounce plated copper. The inner layer is recommended to choose the 1-2 once a solid copper plate, so as to optimize the heat dissipation performance.

The third factor is to optimize the stacked structure. It is great to utilize the inner circuit to block the high-speed signal, so as to reduce the distraction.

The fourth factor is the copper laying strategy. The antenna area should avoid copper. The creepage spacing should be reserved for high-voltage circuits.

The fifth factor is the balance between costs. The FR4 depends on the copper foil and the vias to dissipate the heat. But the metal core substrate has a higher cost than FR4. And it improves the heat dissipation efficiency, making it suitable for the high-power MCPCB.

The final factor is the manufacturing process match. The 2 once copper foil is expensive, and it is difficult to do the fine circuit, but it has great thermal performance. Hence, the design needs to be weighed according to the requirements. The inner layer should use the negative copper to improve the yield, and the surface copper layer should avoid the dense circuit area.

Welcome to contact us if you have any request for aluminum PCB: sales@bestpcbs.com.

Why Choose Aluminum PCB Sheet for Battery Management System?

Aluminum PCB sheet are chosen for battery management systems (BMS) for the following reasons:

Efficient Thermal Management Capabilities

The aluminum substrate boasts a thermal conductivity of 160-200 W/m·K, over 500 times that of FR4. This rapidly dissipates Joule heat generated during battery charging and discharging, preventing local cell temperatures from exceeding the safety threshold of 60°C and significantly reducing the risk of thermal runaway.

Balanced Lightweight and Structural Strength

Aluminum’s density is only one-third that of FR4, reducing the weight of the BMS module while maintaining a flexural strength of 150 MPa sufficient to withstand vehicle vibration, meeting the lightweight and seismic design requirements of electric vehicles.

Electrical Insulation Reliability

A ceramic-filled epoxy insulation layer (breakdown voltage >2 kV) effectively isolates the circuitry from the metal substrate in high-voltage battery packs (such as the 800V platform), keeping leakage current below the μA level.

Compatible Thermal Expansion

Aluminum’s thermal expansion coefficient (24 ppm/°C) is close to that of copper foil (17 ppm/°C), reducing the risk of solder joint cracking during charge and discharge cycles and improving BMS reliability in extreme temperatures ranging from -40°C to 125°C.

Passive Cooling Integrated Design

The aluminum substrate acts as a direct heat sink, eliminating the need for additional heat sinks and reducing the BMS module thickness by 30%, making it suitable for space-constrained battery pack layouts.

Cost-Effectiveness

While the cost per board is 20% higher than FR4, the reduction in heat dissipation components and the extension of battery life (increasing cycle life by over 15%) reduce the overall lifecycle cost by approximately 12%.

Environmental Compliance

The aluminum is 100% recyclable, and its production energy consumption is 40% lower than traditional PCBs, meeting the sustainability requirements of the EU’s new battery regulation (mandating a 90% recycling rate by 2027).

Why Choose Aluminum PCB Sheet for Battery Management System?

Applications of Aluminum PCB Sheet in BMS

Battery Module Acquisition Board: Integrated temperature and voltage acquisition chips adapt to the compact structure of soft-pack/cylindrical batteries.
High-Voltage Main Control Board: Carries the main control MCU and isolated communication chip.
Balancing Board: Layouts active balancing MOSFETs/inductors.
Wireless BMS Communication Module: Integrated Bluetooth/Wi-Fi chips.
Fast Charge Interface Protection Board: Carries the high-voltage connector and fuse.
Thermal Management Control Unit: Integrated with an NTC temperature sensor interface.

Aluminum PCB Heat Dissipation Solution for BMS

Customizing heat dissipation paths by functional module

Based on the heat dissipation differences among modules within the BMS, such as the acquisition board, main control board, and balancing circuit, the copper layer thickness and routing layout of the aluminum substrate are adjusted.
For example, the high-voltage main control board of a leading automaker utilizes a 4oz thick copper layer, combined with a localized gold plating process, to reduce the temperature rise in high-current paths by 30%, maintaining a stable temperature of core components below 65°C.

Embedding thermally conductive materials to fill gaps

Introducing low-resistance thermal pads or phase-change materials between the aluminum substrate and the battery module or heat sink casing reduces the contact thermal resistance to below 0.5°C·cm²/W.
Using this solution, a new energy brand reduced the BMS failure rate from 15% to 1% in a -40°C to 125°C cycle test, extending its service life by two years.

Enhanced heat dissipation with micro-heat pipes/vapor chambers

For high-power density scenarios, such as fast-charging ports, heat pipes or vapor chambers (VCs) are embedded within the aluminum substrate to quickly diffuse local hot spots.
During actual testing at 100kW fast charging, this solution reduced temperature variations by 75%, preventing protection plate failure due to local overheating.

Simulation Optimization Reduces Trial-and-Error Costs

Using FloTHERM or Icepak thermal simulation software, fluid-thermal coupling analysis of the aluminum substrate layout was performed.
After adjusting the copper foil distribution, a Tier 1 supplier increased the prototype vibration test pass rate from 85% to 99%, reducing secondary development costs by 40%.

Balancing Lightweight and Cost

A 1.5mm-2.0mm thick 5052 aluminum-magnesium alloy substrate was used, achieving a balance between rigidity and weight.
Compared to copper substrates, this solution achieves a 40% weight reduction and a 25% cost reduction, while also passing automotive-grade vibration and salt spray tests (ISO 16750/ASTM B117).

Aluminum PCB Heat Dissipation Solution for BMS

BMS Aluminum PCB Sheet Design Guide

Below are BMS aluminum PCB sheet design guideline:

1. Layer Stackup Optimization

Use a three-layer structure: circuit layer (35μm–280μm copper foil), insulation layer (0.1mm–0.3mm epoxy with ≥0.8W/m·K thermal conductivity), and metal base (1.0mm–2.0mm aluminum).
Validate via thermal simulation (e.g., FloTHERM) to refine copper distribution and reduce temperature variation by up to 75% in high-temperature environments.

2. Trace Routing for Thermal and EMC Compliance

Place high-current devices (e.g., MOSFETs) near substrate edges for efficient heat dissipation. Use “wide-narrow-wide” traces to minimize hotspots.
Maintain ≥2mm clearance between critical signals (CAN buses) and high-current paths. Add shielding or ferrite beads to suppress noise.

3. Thermal Integration Solutions

Embed micro heat pipes or vapor chambers (VCs) to spread localized heat. Pair with low-thermal-resistance pads (≤0.5℃·cm²/W) for gap filling.
For high-power modules (e.g., DC converters), use liquid-cooled substrates with 2mm-thick, 3W/m·K thermal pads to limit temperature rise to ≤20℃.

4. Mechanical Fixation and Surface Treatment

Secure PCBs with bolts spaced ≤50mm apart. Add edge positioning holes to prevent assembly misalignment.
Apply ENIG (≥5μm thickness) to enhance solderability and corrosion resistance, extending salt spray resistance to 168 hours (ASTM B117).

5. Multi-Dimensional Testing Protocols

Thermal: Monitor key component rises (e.g., ≤15℃ at 85℃/72hr). Conduct thermal shock (-40℃~125℃/100 cycles) with deformation ≤0.1mm.
Electrical: Validate voltage/current accuracy (cell error ≤±5mV) and pass 2500V DC/1min insulation tests.
Environmental: Ensure no cracks under vibration (10Hz–2000Hz, 0.5g²/Hz PSD) and no blistering after 85℃/85%RH/168hr tests.

Immersion Tin Direct Thermal Path Copper PCB

Friday, August 8th, 2025

In high-power electronics, heat management is one of the most important factors for ensuring long-term performance and reliability. When components operate at high temperatures, efficiency drops, solder joints weaken, and overall lifespan shortens. This is where Direct Thermal Path (DTP) Copper PCBs come in — they channel heat away from components quickly and efficiently.

However, the performance of a DTP PCB depends not only on its core structure but also on the surface finish. One popular choice is immersion tin, a cost-effective, lead-free finish with excellent solderability. In this article, we’ll explore what immersion tin is, how it works with thermal path copper PCBs, and why it’s worth considering for your next high-power design.

Immersion Tin Direct Thermal Path Copper PCB

What is Immersion Tin Surface Finish?

Immersion tin is a metallic coating applied over the exposed copper areas of a PCB. Its primary purpose is to protect copper from oxidation before soldering and to provide a smooth, solder-ready surface.

Unlike hot air solder leveling (HASL), which deposits solder on copper pads, immersion tin uses a chemical displacement process. During manufacturing, the copper surface is immersed in a chemical bath containing tin ions. The tin replaces the copper atoms at the surface, creating a thin, uniform coating — typically 0.8–1.2 micrometers thick.

Key characteristics of immersion tin:

Lead-free and RoHS compliant, meeting environmental standards.
Flat and smooth surface — ideal for fine-pitch components.
Good shelf life when stored in controlled conditions.
Uniform coating even on small pads and vias.

Because it’s applied chemically, immersion tin creates a consistent and even finish across the PCB, which is important for solder joint quality in DTP designs.

What is Direct Thermal Path Copper PCBs?

A Direct Thermal Path PCB is designed to give heat a straight path from heat-generating components to a metal base, usually copper or aluminum.

In a standard FR4 PCB, heat has to travel through dielectric layers before reaching a heat sink, which slows down dissipation. In a DTP design, thermal vias and copper cores bypass most of the insulating material, providing a low-resistance path for heat flow.

Typical DTP PCB structure:

Copper circuitry layer for electrical connections.
Dielectric layer with high thermal conductivity.
Copper core or base acting as the main heat spreader.
Thermal pads directly under high-power components.

This is especially useful for LED lighting, power electronics, and automotive modules, where thermal management is critical.

What is Direct Thermal Path Copper PCBs?

Advantages of Immersion Tin for Thermal Path PCBs

When you combine a DTP PCB with an immersion tin surface finish, you get a unique balance of thermal performance and solder reliability.

Immersion tin bonds well with solder, creating strong and consistent joints — essential for high-reliability assemblies.
Ideal for fine-pitch ICs and surface mount components, where accurate placement matters.
Even on complex copper geometries, the tin layer is consistent, preventing uneven soldering.
Maintains low contact resistance for both electrical signals and heat conduction.
Fully meets RoHS environmental requirements.
More affordable than ENIG (Electroless Nickel Immersion Gold) while still offering high performance.

DTP PCB Design and Manufacturing

Designing and manufacturing Direct Thermal Path PCBs with immersion tin involves careful material and process choices.

1. Material Selection

Copper core thickness can range from 0.5 mm to several millimeters, depending on the heat load.
The dielectric must have high thermal conductivity (2–8 W/m·K or higher).

2. Thermal Simulation & Layout

Engineers place components so that heat flows directly to the copper base.
Thermal vias may be added under components to enhance the path.

3. Drilling and Plating

Mechanical drilling or laser drilling creates precise holes for both electrical and thermal transfer.

4. Applying Immersion Tin

After etching the copper circuitry, the exposed pads are cleaned and immersed in a tin bath.

This step happens late in the process to prevent oxidation before shipment.

Direct Thermal Path PCB Applications

DTP PCBs with immersion tin are used in industries where both high thermal performance and strong solderability are important:

High-Power LEDs — Street lighting, stage lighting, and automotive headlights.
Power Supply Modules — DC-DC converters, AC-DC adapters.
Motor Controllers — Industrial automation and robotics.
RF Power Amplifiers — Heat-sensitive high-frequency components.
Electric Vehicles — Battery management systems (BMS) and onboard chargers.

By providing a direct copper heat path, these PCBs keep components cooler and extend their lifespan.

Comparing Immersion Tin with Other Surface Finishes

Surface Finish	Solderability	Shelf Life	Cost	Thermal Path Suitability
Immersion Tin	Excellent	6–12 months	Medium	Very Good
HASL (Lead-free)	Good	Long	Low	Fair
ENIG	Excellent	12+ months	High	Excellent
OSP	Good	6 months	Low	Good
ENEPIG	Excellent	12+ Months	Higher	Excellent

Immersion tin offers a strong middle ground — better performance than OSP or HASL for DTP boards, at a lower cost than ENIG.
