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%

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.

Double Sided Copper Clad PCB Design Guideline

Below is double sided copper clad PCB design guideline:

1. Layout Strategy

Group analog/digital/power components separately.
Place critical signals (e.g., clocks, RF) away from board edges.
Avoid stacking components on opposite sides where possible.

2. Routing Basics

Use top layer for primary signals; bottom for ground/power planes.
Keep trace width ≥8 mil (0.2mm) for 1A current.
Maintain ≥6 mil spacing between traces to reduce crosstalk.

3. Via Best Practices

Use through-hole vias for layer-to-layer connections.
Drill size: 0.3–0.5mm (12–20 mil) with ≥0.2mm annular ring.
Limit via density to <50 per sq. inch to avoid drilling issues.

4. Thermal Considerations

Add 3–5 thermal vias under high-power components (e.g., MOSFETs).
Use copper pours (≥70% coverage) on both layers for heat dissipation.
Connect surface-mount pads to ground planes via thermal relief.

5. Power & Ground Design

Avoid splitting ground planes unless necessary.
Place 0.1µF decoupling capacitors near IC power pins.
Connect analog/digital grounds at a single point (star grounding).

6. Manufacturability Tips

Add via-based test pads for critical nets.
Open solder mask ≥0.3mm around pads for wave soldering.
Check DFM: silkscreen text ≥1mm, avoid acute trace angles.

7. Surface Finish Selection

Choose HASL for cost-effective through-hole assembly.
Use ENIG for fine-pitch SMT (e.g., 0.4mm BGA).

8. File Preparation

Export Gerber layers: top/bottom copper, solder mask, silkscreen.
Separate NPTH/PTH drill files.
Include assembly drawings with polarity/orientation marks.

Double Sided Copper Clad PCB Design Guideline

How to Make Double Sided Copper Clad PCB Board?

1. Raw Material Preparation

Substrate Selection: Use FR-4 (fiberglass-reinforced epoxy) or other flame-resistant materials as the base substrate.
Copper Foil: Cut copper foils to match the PCB dimensions, ensuring uniform thickness (typically 18–70 µm).

2. Copper Foil Cleaning

Degrease copper foils using alkaline solutions to remove oils and contaminants.
Apply micro-etching (e.g., sodium persulfate) to roughen the surface for better adhesion.

3. Lamination Process

Layer the substrate between two copper foils.
Use vacuum presses to apply heat (170–200°C) and pressure (20–40 kg/cm²) for 60–120 minutes, bonding the layers.

4. Drilling Holes

Use CNC drills to create via holes and component mounting holes.
Deburr holes to remove debris and ensure smooth walls.

5. Electroless Copper Plating (Through-Hole Metallization)

Immerse the board in a catalyst solution (e.g., palladium chloride) to activate non-conductive holes.
Deposit a thin layer of copper (0.2–0.5 µm) via chemical plating to connect both sides.

6. Dry Film Photoresist Application

Laminate dry film photoresist onto both sides of the board.
Expose the film to UV light through a circuit pattern mask, hardening the exposed areas.

7. Electroplating (Pattern Plating)

Plate additional copper (20–30 µm) and a tin-lead layer (8–12 µm) over the exposed traces.
The tin acts as an etch resist during the next step.

8. Etching Process

Strip the unexposed photoresist using sodium hydroxide.
Etch away unwanted copper with ammonium persulfate or cupric chloride, leaving the plated traces.

9. Solder Mask Application

Coat both sides with epoxy-based solder mask ink.
Expose and develop to retain mask only over non-conductive areas.

10. Surface Finish

Apply Hot Air Solder Leveling (HASL) for tin-lead coating or OSP (Organic Solderability Preservative) for lead-free options.

Aluminum PCB Design Guidelines

1. Thermal Viability First

Calculate required thermal vias using: N = (P × Rth)/ΔT, where P = power (W), Rth = thermal resistance (°C/W), and ΔT = max allowable temp rise. Aim for ≥6 vias (0.5mm dia) under high-power devices.
For LEDs >1W, ensure die attach area covers ≥70% of the aluminum base. Use white solder mask to reflect unused light and reduce thermal load.

2. Component Placement Logic

Group heat sources (e.g., regulators, drivers) in a central “thermal zone” with direct aluminum exposure. Keep analog/RF components ≥5mm from this zone to avoid thermal noise.
Orient power transistors with drain/collector pads parallel to aluminum grain direction for optimal heat spreading.

3. Copper-Aluminum Bonding

Use 35µm (1oz) copper for signals; switch to 70µm (2oz) for power traces. Avoid abrupt copper weight transitions (>1oz difference) to prevent lamination cracks.
Specify “button plating” for plated through-holes (PTHs) to reinforce aluminum-copper joints.
Dielectric Layer Control
Request dielectric thickness tolerance of ±10%. Thinner layers (50µm) improve thermal performance but risk electrical breakdown; validate with V = E × d (E = dielectric strength, d = thickness).
For high-voltage (>100V) designs, add a 50µm polyimide overlay on critical traces.

4. Mechanical Stress Mitigation

Add 1mm chamfered edges to aluminum cores to prevent sharp corners causing board flex. Use 3M™ thermal tapes instead of screws for non-critical assemblies to reduce thermal impedance.
For assemblies with >5kg weight, specify aluminum thickness ≥2.0mm and add 2mm mounting holes spaced ≥50mm apart.

5. Assembly Compatibility

Require wave soldering temps ≤260°C for aluminum PCBs. Use low-melting-point solder (Sn42/Bi58) for mixed-technology boards (SMT + through-hole).
Add 0.2mm solder mask dams between fine-pitch SMT pads to prevent solder wicking on aluminum surfaces.

6. Testing Protocols

Perform IR thermal imaging at 80% max load for 2 hours. Target ΔT <15°C between hottest component and ambient. Validate dielectric integrity with 500V Hipot testing; fail if leakage current >5mA.

Aluminum Base PCB Manufacturing Processes

Below are aluminum base PCB manufacturing processes:

1. Material Preparation

Aluminum Base Selection: Choose alloy (e.g., 5052, 6061) based on thermal/mechanical needs. Thickness ranges 1.0–3.0mm.
Surface Treatment: Clean and roughen aluminum via chemical etching to improve dielectric adhesion.

2. Lamination

Dielectric Layer Application: Coat aluminum with thermally conductive epoxy (1–8 W/m·K) or ceramic-filled prepreg.
Copper Foil Bonding: Press 1–10oz copper foil onto the dielectric under 180–200°C and 15–20 kg/cm² pressure.

3. Circuit Imaging

Dry Film Application: Laminate photosensitive dry film onto copper. Expose to UV light through a circuit mask.
Etching: Use alkaline solution (e.g., sodium hydroxide) to remove unexposed copper, leaving precise traces.

4. Via Formation

Mechanical Drilling: Drill microvias (0.2–0.5mm) using carbide bits. Deburr holes to remove aluminum shavings.
Plating: Electroplate holes with 20–35µm copper to ensure conductivity and thermal transfer.

5. Solder Mask Application

Screen Printing: Apply epoxy-based solder mask (white/black) to protect traces. Cure at 150°C for 60 minutes.
Secondary Coating: Add high-temperature polyimide tape on power traces for >200°C environments.

6. Surface Finish

HASL (Hot Air Solder Leveling): Dip PCB in molten solder (Sn63/Pb37) for cost-effective finish.
ENIG (Electroless Nickel Immersion Gold): Apply 3–5µm nickel and 0.05–0.1µm gold for fine-pitch SMT.

7. Profiling & Testing

Routing: Cut boards to shape using CNC machines. Add chamfered edges to prevent assembly damage.
Electrical Testing: Use flying probe or bed-of-nails to verify continuity (≤1Ω) and isolation (≥100MΩ).
Thermal Cycling: Expose PCB to -40°C/125°C cycles (5x) to validate reliability.

MCPCB Design, MCPCB Prototype, MCPCB Supplier

Monday, July 28th, 2025

What is MCPCB design?

MCPCB stands for Metal Core Printed Circuit Board. Unlike regular PCBs made with fiberglass, MCPCBs use a metal base—usually aluminum or copper—as their core layer. This helps carry heat away from components. In MCPCB design, attention should be paid not only to the electrical layout but also to the thermal flow and mechanical strength.

MCPCB Design, MCPCB Prototype, MCPCB Supplier

MCPCBs are ideal for LED lights, power supplies, automotive electronics, and high-temperature environments. Their main job is to conduct heat away from sensitive components while maintaining solid electrical performance.

So, what is MCPCB design? It’s the process of creating a printed circuit board with a metal core that balances power, heat, and cost—all in one compact board.

What is the MCPCB definition?

By definition, an MCPCB is a circuit board that contains:

A copper circuit layer for electrical conductivity.

A dielectric layer for insulation.

A metal base for heat dissipation (aluminum or copper).

The “MC” in MCPCB represents the metal core, which is what sets it apart from standard PCBs. This unique core allows the board to perform better in thermal management, giving it a clear edge in high-power applications.

In simpler terms, MCPCB = Metal + Circuit + Insulation, all working together.

How does MCPCB design affect cost and performance?

When done right, MCPCB design helps reduce overheating, extends component life, and cuts maintenance costs. But if the thermal path isn’t optimized or trace routing isn’t clean, you might face issues like:

Poor heat dissipation
Solder joint failure
Component damage
Lower LED brightness

All of this can push your costs up. A smart design, on the other hand, balances performance and cost from the beginning. For example:

Using aluminum instead of copper reduces cost without hurting performance for most LED boards.

Selecting the right dielectric material keeps the board thin while ensuring heat is controlled.

Clear trace paths help maintain signal integrity and reduce EMI.

What’s the difference between MCPCB and standard PCBs?

Standard PCBs use FR4 (a fiberglass-reinforced epoxy) as the core. They work well in normal-temperature environments. But as power or current increases, they heat up quickly. And they don’t cool down fast.

MCPCBs, on the other hand, are built for heat. They use a metal core (usually aluminum) instead of FR4. This change gives them superior thermal conductivity, making them ideal for high-power devices.

Let’s put it in simple terms:

Standard PCB = Best for low-heat, general electronics.

MCPCB = Best for high-heat, high-performance applications.

This key difference changes how you approach layout, stack-up, and assembly. That’s why MCPCB design must be treated differently from standard boards.

Why use MCPCB prototype for testing?

Testing MCPCB prototypes before committing to mass production can save you a ton of money and weeks of lost time.

A prototype helps you:

Test thermal behavior in real conditions
Check for design flaws or unexpected hot spots
Ensure your LED PCB maintains brightness under load
Evaluate material quality from your chosen MCPCB supplier

Also, prototyping speeds up development. You get real data fast. This keeps your timeline tight and your product launch on track.

What are key MCPCB design guidelines?

Designing a metal core PCB takes a different mindset. Follow these essential MCPCB design guidelines:

Know your heat source: Place hot components close to vias or thermal pads.

Use wide copper traces: Helps current flow without resistance.

Choose the right metal base: Aluminum for cost-efficiency; copper for higher thermal performance.

Mind your dielectric layer: Thin layers cool better, but must still insulate properly.

Leave room for expansion: Heat causes expansion. Mechanical stress can break solder joints.

The more you follow these core rules, the better your board will perform and the longer its actual service life will be.

Why is MCPCB design critical for LED PCB?

LEDs are sensitive. As their temperature increases, their brightness drops. At high temps, their lifespan can also shrink dramatically. That’s why LED lighting depends on MCPCBs to manage heat efficiently.

With a properly designed LED PCB, you get:

Brighter output with less energy
Longer LED life
Stable color over time
No flicker or degradation

Poor thermal design can degrade LED performance, even if the rest of the circuit is very robust. MCPCB design can protect LED performance.

If you’re in automotive, medical, or commercial lighting, this can make or break product quality.

How is aluminum PCB better for LEDs?

When comparing aluminum PCBs to standard fiberglass ones for LEDs, aluminum wins by a landslide. Here’s why:

Aluminum conducts heat better: It draws heat away from the LED’s base.

It’s lightweight and strong: Perfect for compact fixtures.

It reduces component failure: Lower heat = longer life.

It’s cost-effective: Compared to copper, aluminum gives great performance without high cost.

Aluminum MCPCBs have become the gold standard for LED applications. They offer the right balance of thermal conductivity, cost, and mechanical strength.

How to choose the right MCPCB supplier?

Key specifications of metal clad PCBs can vary depending on the application, but the typical ranges include:

Base Material: Commonly used aluminium alloys are 5052 and 6061, both offering good strength and thermal properties. While 3003 can be used, it is less typical due to its lower mechanical strength and thermal conductivity.
Thermal Conductivity: Standard aluminium clad PCBs offer thermal conductivity between 1.0 to 2.0 W/mK. Higher values, such as 3.0 W/mK, are available but usually require special high thermal conductivity materials, which may increase cost.
Copper Thickness: The copper layer usually ranges from 1oz to 6oz. The 1oz to 3oz range is most common, but higher thickness is possible for heavy current applications.
Board Thickness: Standard thickness ranges from 0.8mm to 3.2mm, but thinner boards, such as 0.6mm, can also be manufactured based on project needs.
Surface Finish: Typical surface treatments include HASL (Hot Air Solder Leveling), ENIG (Electroless Nickel Immersion Gold), and OSP (Organic Solderability Preservative). The choice depends on the specific assembly process and performance requirements.

These specifications allow metal clad PCBs to deliver efficient heat management and maintain structural integrity under demanding conditions. However, values should be tailored to suit the product’s real-world operating environment for best results.

What is Delamination on an Aluminum Clad PCB?

Delamination refers to the separation between layers. On aluminium boards, it can happen due to poor lamination or thermal stress. Using high-quality bonding materials and strict process control helps avoid this issue. Best Technology uses advanced lamination techniques and thermal cycling tests to ensure reliability.

These boards use a metal base—typically aluminum or copper—to efficiently dissipate heat for LEDs, power modules, and automotive systems. However, the effectiveness of an MCPCB depends heavily on the material chosen for its core and dielectric layers.

At Best Technology, we specialize in custom MCPCB fabrication using materials from leading global brands like Laird, Bergquist, and Ventec. Whether you need aluminum-based MCPCBs for LED lighting or copper-core boards for power electronics, we offer full support from material selection to prototyping and mass production. In this blog, we will share some information about metal core PCB materials, help you to understand MCPCB from the inside to out.

Metal Core PCB Material: Types, Properties & Applications

What Is Metal Core PCB?

A metal core PCB (MCPCB) is a printed circuit board that uses a metal base instead of traditional fiberglass (FR4). This metal base acts as a heat spreader, drawing heat away from components that generate significant thermal energy during operation.

In a typical MCPCB, the structure includes three key layers:

Copper Circuit Layer – for electrical connections.
Dielectric Layer – an insulating layer that separates the copper from the metal core, allowing heat transfer but preventing electrical conduction.
Metal Core (Base Layer) – typically aluminum, copper, or stainless steel, used to conduct heat away from the board.

These PCBs are engineered to handle thermal management more efficiently than standard PCBs. As electronic devices become more compact and powerful, effective heat dissipation becomes more important, and MCPCBs offer a practical solution.

Common Metal Core PCB Materials

There are several options when it comes to metal core PCB material, each with its own unique benefits. The choice depends on factors like thermal requirements, mechanical strength, weight, and budget.

1. Aluminum Core

Aluminum is the most commonly used metal core material in MCPCBs. It is lightweight, cost-effective, and has good thermal conductivity—typically around 205 W/m·K. Aluminum cores are ideal for LED lighting, consumer electronics, and automotive circuits where heat must be dissipated efficiently, but extreme thermal loads are not present. The commonly used aluminum core PCB in Best Technology is 5052, 6061, 3003, here is the datasheet of them:

Property	6061 Aluminum	5052 Aluminum	3003 Aluminum
Material Type	Al-Mg-Si	Al-Mg	Al-Mn
Tensile Strength (MPa)	290 – 350	190 – 260	130 – 200
Yield Strength (MPa)	240	160 – 200	115 – 150
Elongation at Break (%)	10 – 17	12 – 20	15 – 20
Thermal Conductivity (W/m·K)	167	138	159
Density (g/cm³)	2.70	2.68	2.73
Melting Point (°C)	582 – 652	607 – 650	643 – 657

2. Copper Core

Copper is used where superior heat dissipation is needed. It has excellent thermal conductivity—around 385 W/m·K—and is suitable for high-power applications such as power supplies, industrial equipment, and RF systems. While it offers the best performance in terms of heat transfer, it is also heavier and more expensive than aluminum.

3. Stainless Steel Core

Stainless steel is rarely used, but it can be found in certain niche applications where corrosion resistance and mechanical strength are more important than thermal performance. Its thermal conductivity is much lower, around 16 W/m·K, making it suitable only for specific use cases.

Metal Core PCB Material Manufacturers

When choosing a metal core PCB manufacturer, it’s important to work with companies that supply high-quality materials and have a track record of consistency and reliability. Below are some of the leading manufacturers of metal core PCB materials that we cooperating:

Bergquist (Henkel)
Ventec
Polytronics (Taiwan)
Boyu (China)
Laird Technologies
Totking (China)
Dupont Clamcool
XianYang Bode electronic

Why Thermal Conductivity Is Important in MCPCB?

The thermal conductivity of a material refers to the amount of heat it can transfer under stable conditions. Specifically, for a 1-meter-thick material, if the temperature difference between two surfaces is 1°C, and heat transfer occurs through 1 square meter within 1 hour, the quantity of heat transferred is expressed in W/m·K (watts per meter-kelvin). For practical use, K (kelvin) can often be replaced by °C.

The thermal conductivity value depends on the material’s composition, density, moisture content, and temperature. Materials with lower density or non-crystalline structures tend to have lower thermal conductivity, while materials with higher density and metallic bonding structures transfer heat more efficiently.

Generally, materials with low thermal conductivity are referred to as thermal insulators, and those with a conductivity below 0.05 W/m·K are called high-efficiency insulation materials. In contrast, metals typically exhibit high thermal conductivity, which makes them ideal for use in metal core PCBs.

Thermal Conductivity of Common Metals Materials

Metal	Thermal Conductivity (W/m·K)
Silver	429
Copper	401
Gold	317
Aluminum	237
Iron	80
Lead	67
Zinc	34.8

As seen in the table above, silver has the highest thermal conductivity, followed by copper and gold. However, due to cost and practicality, copper and aluminum are the most commonly used metals in MCPCBs. Aluminum strikes a balance between cost, weight, and thermal performance, while copper is chosen for extreme thermal demands.

1W vs 2W vs 3W Thermal Conductivity Differences

When evaluating MCPCB materials, it’s essential to consider not only the core metal but also the thermal conductivity of the dielectric layer. This layer sits between the copper circuitry and the metal base. In the metal core pcb manufacturing, the commonly used dielectric layers are 1W, 2W and 3W.

1W/m·K: Basic dielectric material, suitable for low-power circuits and LEDs with minimal heat output.

2W/m·K: Offers moderate thermal performance, ideal for mid-power LEDs and general electronics.

3W/m·K or higher: Designed for high-power LEDs or circuits that generate significant heat, ensuring efficient transfer to the metal core.

Choosing a higher thermal conductivity dielectric can greatly reduce thermal resistance, leading to better overall cooling performance. But not the higher the better, it should depends on your specific demands.

Aluminum PCB vs Copper Core PCB

When comparing aluminum PCBs and copper core PCBs, the main differences come down to thermal performance, cost, and application needs. Both are types of metal core PCBs (MCPCBs), but they serve different purposes depending on how much heat your circuit generates and how much budget you have.

Aluminum PCB is the most commonly used metal core because it offers a good balance of performance, weight, and affordability. It provides moderate thermal conductivity (around 237 W/m·K) and is suitable for many applications, especially LED lighting, consumer electronics, and automotive circuits where heat is present but manageable. Aluminum is also lightweight, making it easier to handle and mount, especially in devices where weight matters.

Copper core PCB, on the other hand, offers superior thermal conductivity (around 401 W/m·K if used directly thermal path technology), nearly double that of aluminum. This allows it to handle more heat, which is crucial in high-power electronics, RF systems, and industrial power converters. However, copper is heavier and more expensive, so it’s typically used only when the highest level of heat dissipation is required.

Can I Use Aluminum PCB in High Power LED Lighting?

Yes, aluminum PCBs are widely used in high-power LED lighting, especially when paired with high thermal conductivity dielectric materials. These boards effectively dissipate heat away from LEDs, preventing overheating and maintaining light output stability.

However, the design must ensure:

Adequate heat spreading area
Proper thickness of aluminum core (typically 1.0mm to 1.6mm)
High-quality dielectric layer with 2W or 3W thermal conductivity

In cases where LEDs generate extreme heat, consider using copper MCPCBs or combining the aluminum core with external heat sinks for better performance.

How to Choose the Right MCPCB Material for LED Projects?

Selecting the correct metal core PCB material for your LED project involves analyzing the following:

Thermal Output of LEDs

Higher wattage LEDs generate more heat. For low-power LEDs, aluminum with 1W/m·K dielectric is sufficient. For high-power LEDs, choose aluminum or copper with 2W–3W dielectric.

Mechanical Requirements

If the PCB must endure vibration or mechanical stress (e.g., automotive lighting), choose thicker copper for added durability.

Budget Considerations

Aluminum offers a cost-effective balance between performance and price. Copper is more expensive and should be reserved for projects where thermal performance cannot be compromised.

Weight Constraints

In portable or ceiling-mounted LED systems, lightweight aluminum helps reduce the overall weight of the fixture.

Metal Core PCB Applications

LED Lighting: Used in street lights, automotive lights, grow lights, and flood lights to ensure LEDs stay cool.
Power Electronics: Found in motor controllers, inverters, and converters to handle large currents and heat.
Automotive: Used in ECUs, headlights, and battery systems for reliable performance in harsh environments.

IMS Insulated Metal Substrate PCB, IMS PCB

Friday, July 25th, 2025

What is an IMS PCB?

Unlike traditional PCBs that rely on FR4 or other resin-based materials, IMS PCBs use a metal base—typically aluminum or copper. This base is paired with a dielectric layer and a copper circuit layer on top.

It’s not just a circuit board. It’s a thermal solution that keeps devices cool and running longer.

IMS Insulated Metal Substrate PCB, IMS PCB

IMS PCB full form and meaning?

The full form of IMS PCB is Insulated Metal Substrate Printed Circuit Board. It’s a PCB built to move heat away from components. That means better reliability, higher efficiency, and longer lifespan for your electronic products.

In this type of PCB, the metal substrate acts as a heat spreader. The insulation layer isolates the copper circuit from the metal base, while still allowing heat to pass through. It’s a smart design that balances performance with thermal control.

What is IMS material?

The core of every IMS PCB lies in its materials. These layers provide the best thermal and electrical performance. Here’s what you’ll find in a standard IMS stack:

Metal Base Layer: Usually aluminum for cost-efficiency and light weight. Copper is also used when more heat dissipation is required.

Dielectric Layer: A thermally conductive but electrically insulating material. It transfers heat from the circuit layer to the metal base.

Copper Circuit Layer: This is where the actual electrical routing happens. It’s similar to traditional PCB copper layers but optimized for thermal contact.

These three layers form the structure of IMS. The combination is compact, efficient, and powerful—especially in LED lighting, automotive electronics, and power converters.

The insulation layer, in particular, must handle high thermal loads while resisting electrical breakdown. Advanced IMS designs often use proprietary dielectric materials to increase thermal conductivity and reduce overall thickness.

How thick is a IMS PCB?

The thickness of an IMS PCB depends on the application. But typically, here’s what you can expect:

Metal base layer: 0.5mm to 3.2mm

Dielectric layer: 0.03mm to 0.2mm

Copper layer: 0.035mm to 0.2mm

The total thickness usually ranges from 0.8mm to 3.5mm. For LED lighting and compact modules, thinner IMS boards (like 1mm) are common. But in power-heavy designs, thicker boards provide the support and thermal capacity needed.

Some custom builds even exceed 3.5mm if the heat demands are extreme. A thicker aluminum layer enhances mechanical strength and heat dissipation, but it also increases weight and cost. So choosing the right thickness is a balance of thermal needs and design efficiency.

What is the difference between FR4 and IMS PCB?

FR4 PCBs use glass-reinforced epoxy as their core. They are great for general electronics. But FR4 struggles with thermal stress. When high-power components run hot, FR4 doesn’t cool them fast enough. That leads to overheating and failure.

IMS PCBs, on the other hand, are built for thermal performance. The metal base acts like a built-in heat sink. It draws heat away from critical components and spreads it out. That protects the electronics and improves reliability.

Feature	FR4 PCB	IMS PCB
Core Material	Epoxy-based fiberglass	Metal (usually aluminum)
Thermal Conductivity	~0.25 W/mK	1.0–9.0 W/mK or more
Heat Dissipation	Limited	Excellent
Cost	Lower	Slightly higher, but worth it
Mechanical Strength	Moderate	Stronger due to metal core

For everyday consumer electronics, FR4 is fine. But for power-hungry devices, IMS PCBs offer unmatched reliability.

2 layer IMS PCB vs Multilayer IMS PCB

While single-layer IMS boards are most common, especially in LED lighting, 2-layer and multilayer IMS PCBs are gaining ground in complex applications.

2-layer IMS PCB means there are copper circuits on both sides of the dielectric layer, with one metal core layer. These offer more routing options while still allowing good heat dissipation.

Multilayer IMS PCBs, on the other hand, can include several copper layers, separated by insulation, and only one side is connected to the metal base for heat transfer. This allows for complex routing and high component density while keeping thermal control.

Benefits of 2-layer IMS PCB:

Better circuit flexibility
Moderate thermal management
More design freedom

Benefits of Multilayer IMS PCB:

High circuit complexity
Suitable for dense power modules
Thermal performance still superior to FR4

If you’re building a simple LED module, a single or 2-layer IMS may be enough. But if you’re designing a power controller, communication device, or automotive ECU, multilayer IMS is often necessary.

IMS PCB stackup: What to know?

Stackup design is more than just layers, it defines how your board handles heat, power, and performance. A typical IMS PCB stackup looks like this:

Copper circuit layer

Dielectric insulation layer

Metal substrate (usually aluminum)

But there’s room for customization. Here’s what matters:

Copper thickness: Choose 1oz, 2oz, or more depending on current flow.

Dielectric performance: The higher the thermal conductivity (measured in W/mK), the better the heat transfer.

Metal base: Aluminum is the go-to for most. But copper or stainless steel can be used for extreme performance or rigidity.

Surface finish: Choose between HASL, ENIG, OSP, or others based on your assembly process.

Stackup choices directly affect reliability. A poor choice here means components will overheat, solder joints will crack, or performance will drop.

What are the applications of IMS PCB?

IMS PCB is widely used in high power industry.

LED lighting: Keeps high-brightness LEDs cool, extending their life.

Automotive electronics: Used in headlights, sensors, battery modules.

Power converters: Manages heat in inverters and converters.

Industrial control systems: Ensures smooth performance under high power loads.

Communication base stations: Maintains signal integrity and prevents thermal breakdown.

Why choose the right IMS PCB Manufacturer?

At Best Technology, we understand the critical role IMS PCBs play. We’ve spent years perfecting the production process, materials, and stackup customization. Every board we deliver is tested for:

Thermal conductivity
Mechanical strength
Electrical reliability

Whether you need standard single-layer boards or complex multilayer IMS PCBs, we can build it to your exact needs.
