What is Exposed Copper on PCB? PCB Exposed Copper Edge

Friday, August 1st, 2025

When looking at a printed circuit board (PCB), you may notice shiny areas of metal that aren’t covered by the usual green or colored solder mask. These are areas of exposed copper on PCB, and they serve important roles in how the board functions. Exposed copper can be found on pads, traces, or even along the edges of the board. But why is the copper left uncovered? And how do you design a PCB to safely include exposed copper?

In this article, we’ll explore the meaning, purpose, types, and design considerations for exposed copper on PCB, including how to manage its risks and where it’s commonly used.

What is Exposed Copper on PCB? PCB Exposed Copper Edge

What Does Exposed Copper on PCB Mean?

In a PCB, exposed copper refers to areas where the copper layer is intentionally left uncovered by solder mask or surface finish. Normally, copper traces and pads are coated with a protective layer to prevent oxidation and corrosion. However, in certain parts of the board, copper is left exposed for electrical or mechanical reasons.

You’ll typically see exposed copper in places where components need to be soldered or where the board makes direct contact with another surface, such as in connectors or test points. These areas must have direct electrical contact, and that means the copper needs to remain accessible.

Where Is Copper Usually Exposed?

Component pads: These areas must be exposed for soldering.
Test points: Used for measuring signals during testing.
Thermal reliefs: Copper areas used to help dissipate heat.
Edge connectors: Known as pcb exposed copper edge, these are found on plug-in boards.
Copper pours: Large copper areas, sometimes left exposed to improve thermal or grounding performance.

Purpose of Designing Exposed Copper on PCB

Designing with exposed copper is a common and often necessary practice. Below are some of the most common reasons designers choose to expose copper on a PCB.

1. Electrical Contact

Soldering requires exposed copper. All component pads, whether for surface mount or through-hole components, need to be bare so solder can properly adhere and form a good electrical connection.

In addition to pads, test points are exposed copper areas used during assembly and troubleshooting. Probes can be placed on these spots to measure voltages or signals.

2. Thermal Management

Copper is an excellent conductor of heat. In high-power applications, such as LED lighting, motor drivers, or power supplies, leaving copper exposed can help manage heat by allowing it to dissipate more efficiently. Large exposed copper plates can act like heat sinks.

3. Grounding and Shielding

In many designs, especially in radio frequency (RF) or high-speed digital circuits, exposed copper design PCB layouts include areas for grounding or electromagnetic interference (EMI) shielding. A pcb exposed copper edge can also be connected to ground and used as part of the shielding structure to protect signal integrity.

4. Cost Considerations

Leaving copper exposed in non-critical areas can reduce costs. Surface finishes like ENIG or HASL add expense, so in low-cost or temporary boards, some copper may be left bare to save on manufacturing steps.

Types of Exposed Copper PCB Designs

There are several ways exposed copper is used in PCB layouts, each serving a specific function depending on the design goals. Below are the most common types you’ll find, along with their applications and things to watch out for.

1. Exposed Copper Pads

Exposed copper pads are the most widely used type of exposed copper in any PCB. These are the metal areas where components are soldered onto the board. By design, they must remain uncovered to allow solder to create a solid electrical and mechanical connection between the component leads and the PCB’s copper layers.

In addition to component soldering, some exposed pads are used for mechanical support or to connect heat-generating parts to large copper pours for better heat dissipation. Proper surface finish on these pads—such as HASL or ENIG—helps prevent oxidation and improves solderability.

2. Exposed Copper Traces

In some designs, traces (the thin copper lines connecting different components) are intentionally left exposed. This is less common than exposed pads, but it’s done in specific cases where designers need direct access to the trace for testing or where the trace carries high current and benefits from better heat dissipation.

One common use for exposed copper traces is creating test points. By leaving a section of trace uncovered, engineers can place probes directly on the trace during testing or troubleshooting.

3. PCB Exposed Copper Edge

A pcb exposed copper edge refers to copper that runs right to the edge of the PCB and remains exposed for functional use. This is typically found in boards that need to connect to sockets or other boards via edge connectors. In these cases, the copper along the edge acts as contact points and must remain exposed for reliable electrical connection.

This type of exposed copper is also used for grounding purposes. For example, in RF circuits or high-speed digital designs, the board edge may have exposed copper connected to ground to reduce electromagnetic interference (EMI). Some designs use edge plating, where the copper is plated along the entire edge of the board to create a continuous conductive path.

What Is the Clearance of Copper to Edge of PCB?

When designing PCBs, copper-to-edge clearance is critical. Copper should not be placed too close to the edge unless it is meant to be exposed. If copper unintentionally gets too close to the edge, it can cause manufacturing problems or failures in the field.

Industry Guidelines

Standard practice, according to IPC standards, recommends at least 0.25mm (10 mils) clearance between copper and the board edge. This clearance prevents copper from being damaged or exposed during board cutting.

Edge Copper Design

If you’re designing a pcb exposed copper edge, such as for a connector or grounding point, you can extend copper to the edge, but it must be plated and processed correctly. Special instructions are needed for the manufacturer to plate the edges and prevent delamination.

How to Design a PCB with an Exposed Copper Plate?

Designing exposed copper areas requires planning and proper use of your PCB design software.

Step 1: Define Copper Areas

Use copper pours, pads, or large planes for the areas you want exposed. Ensure they are connected to the correct net, whether ground, power, or signal.

Step 2: Disable Solder Mask

In your PCB layout tool, disable the solder mask over these areas. This is done by creating a solder mask opening in the relevant layer.

Step 3: Edge Exposure

For pcb exposed copper edge designs, extend the copper to the edge of the board. Indicate this clearly in your mechanical drawings. Some manufacturers require a note to plate the edge.

Step 4: Selective Surface Finish

Decide whether the copper will remain bare or have a finish like HASL (Hot Air Solder Leveling) or ENIG (Electroless Nickel Immersion Gold). These finishes prevent oxidation and improve durability.

Risks and Challenges with Exposed Copper PCB

While exposed copper on PCB serves many useful purposes, it comes with challenges.

Oxidation and Corrosion

Copper oxidizes quickly in air, forming a dull brown or green layer. This can reduce conductivity and make soldering difficult. Moist environments accelerate this process.

Short Circuits

Exposed copper is more likely to cause shorts if it touches other metal objects. Extra care is needed in design and assembly to avoid accidental contact.

Handling Risks

Bare copper areas can be scratched or contaminated during handling. Fingerprints, dust, or moisture can affect performance. Protective packaging and careful assembly help reduce these risks.

Exposed Copper Design Guidelines in PCB Layout

Here are some helpful tips for designing exposed copper areas safely:

Maintain clearance from high-voltage areas unless insulation is provided.
Use protective coatings like conformal coating if the board will be exposed to harsh environments.
Clearly indicate exposed copper areas in your Gerber files and fabrication notes.
For pcb exposed copper edge, work with your manufacturer to ensure proper plating and durability.
Use thicker copper (e.g., 2 oz) for large exposed areas meant for heat dissipation or high current.

FAQs

1. How to remove copper from PCB board?

Copper can be removed through chemical etching using ferric chloride or similar solutions. It can also be scraped off mechanically or milled with CNC tools.

2. What happens to exposed copper?

Exposed copper oxidizes when exposed to air and moisture. This can affect electrical performance, so protective finishes or coatings are often applied.

3. Can exposed copper PCB be used outdoors?

Not directly. Outdoor use requires additional protection, like conformal coating, to prevent corrosion. Without protection, copper will degrade quickly.

4. How do I prevent oxidation on exposed copper areas?

Apply coatings such as OSP (Organic Solderability Preservative), clear lacquer, or conformal coating. Using surface finishes like ENIG or HASL also helps.

5. What surface finish is best if I want partial copper exposed?

ENIG and HASL can be applied selectively. Masking during the finishing process allows partial copper exposure where needed.

6. Is exposed copper safe for high-voltage applications?

Not unless proper spacing and insulation are used. High voltage requires strict clearance and protection to avoid arcing or shorts.

7. What’s the difference between exposed copper and plated finish?

Exposed copper has no added layer, while plated finishes like ENIG or HASL add protection and improve performance.

What is an aluminium substrate PCB? Metal core PCB

Friday, August 1st, 2025

An aluminium substrate PCB is a metal core PCB that uses aluminum as its base layer instead of fiberglass. This design improves heat dissipation, strengthens the board, and enhances reliability.

What is an aluminium substrate PCB? Metal core PCB

It’s widely used in high-power applications like LED lighting and power supplies because it keeps components cooler and extends their lifespan. With excellent thermal performance and solid durability, aluminum PCBs are a smart choice for demanding electronic designs.

What is aluminum substrate?

The aluminium substrate in a PCB refers to the base layer made from aluminium instead of standard fiberglass. In a typical PCB, this layer would be FR4 or other resin materials. But with aluminium substrate PCBs, the core material is metal—specifically aluminium.

This aluminium base gives the PCB a solid foundation. It’s known for exceptional thermal conductivity and mechanical strength. When electronics generate heat (which they always do), this base layer helps pull the heat away fast. That means better performance, less risk of damage, and a longer product lifespan.

Aluminium also gives the board added durability. In harsh environments, it resists physical stress and corrosion better than many other substrates.

What is substrate in PCB?

To put it simply, a substrate in a PCB is the backbone. It’s the main layer that supports everything else. Think of it as the canvas where all the components and copper traces are placed.

The choice of substrate affects how a PCB behaves—its strength, heat resistance, flexibility, and even cost. Most traditional PCBs use FR4, a fiberglass-reinforced epoxy laminate. But when you need better thermal performance, a metal core like aluminium becomes the better option.

The aluminium substrate works by absorbing and dispersing heat, unlike FR4, which traps it. This becomes crucial in power devices, LEDs, and RF systems.

What is the difference between aluminum and FR4 PCB?

The contrast between aluminium and FR4 PCBs is more than just materials—it’s about function, reliability, and endurance.

Material: Aluminium PCBs have a metal core. FR4 PCBs use a glass epoxy material.

Thermal Conductivity: Aluminium wins. It conducts heat away quickly. FR4 holds onto heat, which can cause issues in high-power circuits.

Durability: Aluminium is tougher. It resists wear, shock, and even moisture better.

Weight: FR4 is lighter and more flexible, which is good for some consumer electronics.

Cost: Aluminium PCBs tend to be more expensive to produce but save money by increasing product lifespan and reliability.

So, while both have their place, aluminium PCBs provide real advantages in power-driven or heat-sensitive applications.

Why is aluminum no longer used in integrated circuits?

There was a time when aluminium was the go-to material for IC interconnections. It worked well in early semiconductor technologies. But as chips became smaller and faster, aluminium began to show limits.

Why? Copper is more conductive than aluminium. That means it handles signals faster and uses less power. It also allows for smaller, more compact designs.

Aluminium hasn’t disappeared, though. It’s just moved to a different job—serving as the base in PCBs where strength and heat transfer matter most.

Can high frequency PCB replace aluminium PCB?

High-frequency PCBs are designed to handle fast signals with minimal loss. They use specialized materials like PTFE (Teflon) to maintain signal integrity. But they don’t handle heat as well as aluminium PCBs.

So, can one replace the other? Not really. They serve different purposes. High-frequency PCBs are great for communication systems, radar, and RF devices. Aluminium PCBs are perfect when heat is a big issue—like in power supplies or LED systems.

That said, some advanced designs do combine both features. But in most cases, high-frequency and aluminium PCBs are used in their own unique ways.

Why use aluminium-substrate-PCB for LEDs?

LEDs are efficient light sources, but they generate concentrated heat. If not properly managed, that heat shortens lifespan, dims brightness, and even causes failure. That’s why aluminium-substrate-PCBs are a top choice for LED systems.

Also, aluminium PCBs provide a stable platform. They resist bending or cracking, even in high-humidity or high-temperature environments.

When used in LED strips, light panels, or automotive lights, aluminium PCBs ensure consistent brightness, lower energy loss, and better reliability.

Energy savings also come into play. With better heat dissipation, less power is wasted as heat. That means more energy is turned into light.

What are the pros and cons of aluminum PCB?

Like every technology, aluminium PCBs come with benefits and some limitations. Let’s look at both sides.

Pros:

Superior Heat Dissipation: This is the biggest win. Aluminium handles heat far better than FR4.

High Strength: Aluminium resists cracking, breaking, and vibration. That makes it ideal for industrial and automotive applications.

Longevity: Better cooling leads to longer component life. That reduces maintenance and repair costs.

Eco-Friendly: Aluminium is recyclable. That makes it a green choice for modern electronics.

Thermal Stability: It maintains performance even when temperatures rise.

Cons (but minimal):

Higher Cost: Aluminium PCBs cost more to produce than FR4.

Less Flexibility: Aluminium is rigid. It’s not suitable for bendable or foldable circuit designs.

Machining Complexity: Cutting and drilling aluminium is harder than standard boards.

If your application needs thermal stability, strength, and reliability, the pros easily outweigh the cons.

What are aluminum PCBs used for?

The reach of aluminium PCBs is wide. Their applications span multiple industries and product types.

LED Lighting: From household bulbs to industrial fixtures, aluminium PCBs keep LEDs cool and long-lasting.

Automotive Electronics: Think dashboard lighting, engine control systems, and electric vehicle modules.

Power Supplies: High-wattage power converters, inverters, and regulators benefit from aluminium’s heat handling.

Telecom Equipment: Signal amplifiers and antenna systems use aluminium PCBs for thermal control.

Medical Devices: Precision tools like scanners and monitors require stability and heat protection.

Consumer Products: High-performance gadgets like gaming devices, laptops, and audio systems often use metal core boards to ensure smooth operation.

No matter the product, if heat or durability is a concern, aluminium-substrate-PCB is often the right solution.

Conclusion:

Aluminium substrate PCBs are more than just metal-backed boards. They are performance boosters. They protect your devices from heat, shock, and failure. From LED lighting to telecom and automotive systems, these boards make sure devices run cooler, longer, and more efficiently.

If you’re designing products that need to handle heat, perform reliably, and last longer—aluminium PCBs are a smart, solid investment.

What is an MCPCB LED Strip? MCPCB Design

Thursday, July 31st, 2025

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

What is MCPCB LED?

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

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

Why use MCPCB for LED strip lights?

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

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

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

Longer lifespan: Cooler LEDs mean longer use.

More stable output: No flickering or fading over time.

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

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

How does MCPCB design affect LED strips?

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

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

Dielectric layer: Transfers heat while keeping electrical isolation.

Copper circuit layer: Routes electricity to the LEDs.

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

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

Can MCPCB design improve LED lifespan?

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

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

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

No yellowing of lenses

No cracking of solder joints

No degradation of LED chip efficiency

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

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

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

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

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

How to choose the right LED PCB strip?

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

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

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

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

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

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

How to customize an MCPCB LED strip?

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

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

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

Thermal conductivity: Select different dielectric materials for performance.

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

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

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

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

Where is MCPCB LED used most?

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

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

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

Medical devices: Surgical lights and diagnostic equipment.

Industrial machines: Workstation lighting, control panels.

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

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

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

Conclusion:

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

What is Cu Inlay PCB? Copper Inlay PCB Market

Thursday, July 31st, 2025

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

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

What Is Cu Inlay PCB?

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

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

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

What is Cu Inlay PCB? Copper Inlay PCB Market

What Is the Working Principle of Inlay Copper in PCB?

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

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

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

Why Inlay Copper in the PCB?

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

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

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

Benefits of Copper Inlay PCB

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

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

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

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

Copper Core PCB vs Copper Inlay PCB

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

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

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

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

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

Factors Affect Copper Inlay PCB Price

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

1. Copper Inlay Size and Thickness

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

2. Board Size and Layers

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

3. Surface Finishes and Testing

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

4. Order Quantity

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

5. Price Range

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

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

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

Applications of Inlay Copper PCB

Copper inlay PCBs are found in various high-performance industries. They are ideal for power electronics, where current and thermal reliability are critical.

Here are typical applications:

Electric Vehicles (EV): Power inverters, charging systems, battery control units.
Industrial Equipment: Motor drives, programmable logic controllers (PLCs), industrial inverters.

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

Wednesday, July 30th, 2025

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

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

Aluminium Based PCB Manufacturer

What Is Aluminium PCB?

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

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

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

What Are the Pros and Cons of Aluminum PCB?

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

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

But they also have some limitations:

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

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

Aluminium PCB Material Properties

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

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

What is Thick Copper PCB? PCB Copper Thickness vs Current

Tuesday, July 29th, 2025

A thick copper PCB refers to a printed circuit board that uses a higher amount of copper than a standard PCB. Typically, standard PCBs have copper thickness ranging from 0.5 oz to 2 oz per square foot. However, when the copper thickness is 3 oz or more per square foot, it is classified as a thick copper PCB.

These boards are built for handling high current, enhanced heat dissipation, and strong mechanical performance. You’ll find them in power electronics, electric vehicles, solar inverters, and industrial machinery—wherever reliability and power handling are critical.

At Best Technology, we specialize in custom thick copper PCB manufacturing. Whether you need 3 oz or 20 oz copper, our engineering team supports your design with precision, reliability, and fast delivery. We also provide full traceability and strict quality control, making sure each board meets your performance needs.

What is Thick Copper PCB? PCB Copper Thickness vs Current

Advantages of Thick Copper PCB

1. High Current Carrying Capacity

Thicker copper allows your PCB to carry more current through its traces without causing excess heat. This helps prevent overheating and damage to components. In other words, thick copper gives your board the power capacity it needs to run safely and efficiently.

2. Excellent Thermal Management

Heavy copper spreads heat more evenly across the board and away from sensitive components. This reduces hot spots and helps maintain stable operation. It’s especially useful in environments where heat buildup can be a problem, such as power supplies or LED lighting systems.

3. Increased Mechanical Strength

Thick copper PCBs are more durable. They are less likely to bend, crack, or delaminate during assembly or use. This added strength makes them ideal for heavy machinery, vehicles, and military equipment.

4. Improved Reliability and Product Life

Better current and heat handling reduce stress on the board and components. This leads to longer lifespan and fewer failures, which saves both time and cost in maintenance.

5. Compact and Efficient Designs

You can use narrower traces with thick copper while still meeting your current requirements. This allows for smaller board sizes and space-saving layouts, especially valuable in compact devices.

All of these advantages make thick copper PCBs a smart choice when performance and reliability truly matter.

Standard PCB Copper Thickness Chart

Copper thickness is usually measured in ounces per square foot (oz/ft²) or microns (µm). For every 1 oz of copper per square foot, the actual thickness of the copper layer is about 35 microns, or 1.4 mils. To help you understand how thick copper compares to standard copper, here’s a simple PCB Copper Thickness Chart with typical values.

Copper Weight (oz/ft²)	Thickness (microns)	Thickness (mils)	Common Usage
0.5 oz	~17 µm	~0.7 mil	Signal layers, low-power circuits
1 oz	~35 µm	~1.4 mil	Most standard PCBs
2 oz	~70 µm	~2.8 mil	Power circuits, motor drivers
3 oz	~105 µm	~4.2 mil	Start of thick copper PCB range
4 oz	~140 µm	~5.6 mil	High-power, heat-intensive applications
6 oz	~210 µm	~8.4 mil	Industrial power systems, battery packs
10 oz	~350 µm	~14 mil	Heavy-duty, high-current applications

Whether you are working on a standard 1 oz board or a 10 oz thick copper PCB, the thickness affects everything from electrical performance to thermal control. If you are unsure which thickness suits your project, Best Technology offers expert guidance and custom PCB solutions. We help you choose the right copper weight to match your current load, heat needs, and budget.

PCB Copper Thickness vs Current

One of the biggest reasons to use thick copper is current capacity. As copper thickness increases, it can carry more current without excessive heating. Here’s how it works:

1 oz copper can carry around 1.2A on an inner layer for a 10°C temperature rise.
3 oz copper can carry about 3.6A under the same conditions.
Higher copper weights (like 10 oz) can handle much more, depending on trace width.

This relationship is essential for designing safe and efficient circuits. Using IPC-2221 standards as a guide, engineers can determine how much copper is needed for any given load.

If you’re unsure, tools like the PCB copper thickness calculator can help you find the right copper weight based on your current and design needs.

How to Choose PCB Copper Thickness?

Knowing how to choose PCB copper thickness is essential when designing a board that performs reliably under electrical and thermal stress. The right copper thickness affects current flow, heat management, durability, and even the size of your board. Choosing wisely can improve performance and reduce long-term costs.

1. Understand Your Current Requirements

Start by determining how much current your traces need to carry. Higher current demands thicker copper or wider traces. If your circuit handles heavy loads—like in power supplies or electric vehicles—you’ll likely need thick copper, starting from 3 oz or more.

2. Evaluate Space and Trace Width

Sometimes, there’s limited space on your PCB. If you cannot increase trace width to carry higher current, you can increase copper thickness instead. Thicker copper allows for narrower traces to handle the same current safely, helping you keep your design compact without sacrificing performance.

3. Check for Voltage Drop

Resistance in copper causes voltage drop across traces. Thicker copper has lower resistance, which means less voltage loss. If maintaining consistent voltage is important for your application—like in precision circuits or power regulation—opt for thicker copper to minimize drops.

4. Consider Cost and Board Size

While thicker copper improves performance, it also adds cost and weight. Choose copper thickness that meets your technical needs without over-engineering. For most consumer electronics, 1 oz or 2 oz is enough. For power devices, 3 oz to 10 oz may be needed.

Thick Copper PCB Applications

Power supplies
Converters
Inverters
Battery systems
Motor drives, and charging circuits efficiently
Solar Power Systems
Inverters and control circuits
Military and Aerospace
Industrial Control

Anywhere power, heat, or strength is a concern, thick copper PCBs provide dependable performance.

How to Avoid Thick Copper PCB Delamination?

The delamination of thick copper circuit boards refers to a phenomenon that occurs during PCB manufacturing. Due to insufficient adhesion between the copper foil and the substrate or excessive internal stress, the copper foil and the substrate (such as FR-4 fiberglass board) separate from each other.

While it’s not common, thick copper PCBs can be more prone to this issue if not manufactured properly. Here are some ways to avoid it:

1. Use High-TG Materials

High-TG (glass transition temperature) materials like FR4-TG170 or ceramic can better resist heat and stress.

2. Reliable Lamination Process

Proper lamination ensures strong bonding between copper and substrate. At Best Technology, we use high-pressure lamination and strict process control to prevent delamination.

3. Controlled Soldering Heat

Excessive heat during soldering can damage the board. Controlled soldering ensures minimal thermal stress.

4. Avoid Design Stress Points

Sharp corners and very narrow traces can concentrate stress. A smooth, balanced design reduces risk.

5. Quality Assurance

Choose manufacturers with strong quality systems that include thorough inspection and testing.

What is copper PCB board? Copper clad PCB board

Tuesday, July 29th, 2025

Copper PCB board is a type of circuit board where a thin layer of copper is bonded to an insulating base, usually made from fiberglass, resin, or other non-conductive materials.

What makes copper special is its exceptional electrical conductivity, which ensures fast, stable signal transmission and efficient power delivery. Whether it’s a single sided copper PCB board or a double sided copper clad laminate PCB circuit board, the copper layer is essential for performance, reliability, and heat control.

Available in different thicknesses and configurations, copper clad PCB boards can be tailored to meet the demands of everything from smartphones to medical devices.

Why is copper used in PCBs?

Copper is used in PCBs for one big reason—conductivity. It’s one of the best conductors of electricity. That means signals can move through the board fast, with low resistance. This ensures stable, efficient, and reliable performance in any circuit.

Another reason? Copper is durable. It handles high currents without overheating. It resists corrosion. And it can be etched into very fine lines for dense circuit layouts. Plus, copper is cost-effective. It offers high performance without sky-high prices.

In short, copper keeps signals fast, power stable, and costs low. That’s why it’s the standard across the electronics industry.

How thick is 2 oz of copper on a PCB?

This refers to how much copper is spread over a square foot of board.

2 oz copper thickness equals about 70 microns, or 0.07mm. That may sound thin, but it’s double the thickness of the standard 1 oz copper, which is 35 microns. And that extra thickness brings major benefits:

Higher current-carrying capacity
Better heat dissipation
Stronger, more reliable circuits

Designers choose 2 oz copper when a circuit needs to handle more power or operate in tough environments. It adds strength without a huge increase in cost or size.

What type of copper is used in PCB?

The copper used in PCBs is not just any copper. It’s specifically engineered for electronics manufacturing. The two most common types are:

Electrolytic Tough Pitch (ETP) Copper: This is the standard. It’s over 99% pure and offers great conductivity and flexibility.

Rolled Annealed (RA) Copper: This type is used in flexible PCBs. It’s softer, more bendable, and less likely to crack under repeated movement.

For rigid boards, like your TV remote or thermostat, ETP is ideal. For flexible applications, like foldable phones or wearable devices, RA copper shines.

How to choose PCB copper thickness?

Picking the right copper PCB board thickness depends on your needs. Here are some guiding points:

Current load: More current needs thicker copper. If your board handles power, go for 2 oz or more.

Heat management: Thicker copper spreads heat better, reducing hotspots.

Space constraints: If your design is tight, thinner copper can help save room.

Cost and weight: More copper = more weight and higher cost.

The most common thickness is 1 oz, but 0.5 oz and 2 oz are also widely used. High-power boards may go up to 3 oz or more.

What is a copper clad PCB board?

Copper clad PCB board is a base material, Usually FR4 (fiberglass), CEM-1, or phenolic resin, that’s laminated with a thin layer of copper on one or both sides.

Types of copper clad boards include:

Single sided copper clad board: copper on one side

Double sided copper clad board: copper on both sides

Multilayer boards: multiple layers of copper and insulation stacked together

These boards form the foundation of electronics. Without copper cladding, there’s no signal path, no connectivity, and no functionality.

Types of Copper Clad Boards

There are several variations, each tailored for different needs:

Single sided copper PCB board: Great for simple, low-cost circuits. Common in calculators or basic toys.

Double sided copper PCB board: Used in more complex electronics, offering better routing and signal flow.

Copper clad laminate: This is the raw material, often sold in panels, ready to be etched. Also known as blank copper PCB board.

Double sided copper clad laminate PCB circuit board: Offers flexibility in circuit design. Common in LED lighting and power supplies.

Copper strip PCB board: Used for high-current circuits. Thick copper strips are embedded to carry heavy loads.

Copper clad plate laminate PCB board: Known for high strength, used in industrial environments.

The choice depends on application, current needs, size, and cost.

What is a copper clad board used for?

Copper clad boards are used in every corner of the electronics world.

Consumer electronics
Industrial controls
LED lighting
Automotive dashboards
Medical devices
Communication systems

Their job? To carry signals, distribute power, and provide mechanical support. They’re also vital for EMI shielding, grounding, and signal integrity.

How to remove copper from PCB board?

There are moments in prototyping or repair when removing copper is necessary. Here are some common methods:

Chemical etching: Ferric chloride or ammonium persulfate can dissolve copper. Be cautious, it’s toxic and requires proper ventilation.

Mechanical removal: Sandpaper or a rotary tool can physically grind off copper.

Laser removal: High-end labs use this for ultra-precise control.

Each method has pros and cons. For hobbyists, mechanical methods are safer. For professionals, chemical etching allows for mass removal with precision.

Copper plated PCB board vs copper coated: What’s the difference?

Copper plated PCB boards and copper coated PCB boards may sound similar, but they serve different purposes.

Copper plated PCB board means copper has been electroplated onto certain areas—like holes or edges. This helps with conductivity, especially in via holes and multi-layer connections.

Copper coated PCB board refers to a board where a base material is uniformly covered with copper foil. This is typically done during the lamination stage to form the initial circuit layer.

In short:

Plated = targeted copper application, used for conductivity enhancement

Coated = general copper layer across a surface, used to form the main circuit

Conclusion:

Copper PCB boards play a critical role in modern electronics, offering excellent conductivity, thermal performance, and reliability. Whether it’s a single sided copper clad board, double sided copper PCB board, or a blank copper PCB board, each type supports different circuit needs.

If you’re looking for high-quality copper clad PCB boards, reliable support, or expert advice, we’re here to help.

Metal Core PCB Material: Types, Properties & Applications

Friday, July 25th, 2025

When it comes to managing heat in high-power electronic devices, Metal Core PCBs (MCPCBs) are the go-to solution. 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.
Telecommunications: Applied in RF modules, power amplifiers, and antenna systems.
Consumer Devices: Used in high-performance audio systems and power adapters.

This core serves as the backbone of the PCB, offering strong thermal conductivity, mechanical support, and efficient heat dissipation. These properties make it ideal for high-power circuits where temperature control is critical.

Why use a metal core PCB?

Electronic components, especially high-power LEDs and MOSFETs, generate heat. If that heat stays trapped, it kills performance and shortens lifespan.

Metal core PCB fights this issue head-on. Its design allows heat to transfer quickly from the circuit layer to the metal base, keeping components cool and stable. That means fewer failures, longer device life, and lower maintenance.

They’re not just about heat. MCPCBs also improve structural strength, reduce size, and support higher component density. All these benefits combined make them a go-to for industries like automotive, telecommunication, aerospace, and medical devices.

What are the pros and cons of aluminum PCB?

Every material has its strengths and weaknesses. But in the case of aluminium PCBs, the pros are far more impressive than the cons.

Advantages:

Excellent Thermal Management: Aluminium pulls heat away from hot components, preventing damage.

Lightweight Yet Strong: Compared to copper, aluminium offers solid durability at a lower weight.

Cost-Effective: It’s more affordable than copper but delivers reliable thermal conductivity.

Eco-Friendly: Aluminium is recyclable and non-toxic, helping meet sustainability goals.

Improved Dimensional Stability: The structure remains stable even under changing temperatures.

Disadvantages (Very Few):

Slightly less flexible than FR4 in design.

Electrical insulation must be carefully managed to avoid short circuits.

Still, for most applications, these drawbacks are easily handled by professional manufacturers.

What does aluminum core mean?

Aluminum core PCB refers to a circuit board with three main layers:

Copper Circuit Laye: This is where your electronic components sit.

Dielectric Layer: An insulating layer that transfers heat to the core while isolating electricity.

Aluminium Base Layer: A thick base of aluminium that provides strength and heat sinking.

This core turns a standard PCB into a high-performance solution, especially for high-current and high-heat devices.

Why choose an aluminum core PCB?

There are many reasons to choose aluminum core PCB instead of traditional PCB. Its core advantages go far beyond temperature control. Here’s why they shine:

Superior Heat Dissipation: Keep components safe even in the most demanding power applications.

Durable Construction: Withstands mechanical stress and harsh environments.

Compact Design: Allows for smaller, thinner devices without sacrificing reliability.

Better Reliability: Lowers the risk of overheating, which often causes circuit failure.

Improved Energy Efficiency: Less heat means less energy wasted, which is a win in power-sensitive applications.

Great for LED Applications: Aluminium PCBs have become the backbone of LED lights due to their excellent thermal properties.

If your end product needs to perform well under pressure, aluminium core PCBs are a rock-solid choice.

How is aluminium PCB made?

The aluminium PCB manufacturing process is both precise and efficient. Here is a brief process of the aluminum substrate PCB factory:

Raw Material Preparation – Aluminium base is selected, cleaned, and pre-treated for bonding.

Dielectric Layer Application – An insulating, thermally conductive layer is laminated onto the aluminium.

Copper Cladding – A copper sheet is bonded on top of the dielectric.

Image Transfer – Circuit patterns are printed and developed on the copper layer.

Etching – Unwanted copper is removed, leaving the circuit behind.

Solder Mask and Silkscreen – Protective coatings and labels are added.

Surface Finish – Finishing like ENIG, HASL, or OSP is applied to improve solderability.

Testing – Electrical and visual inspections are done to ensure perfection.

BEST Technology’s modern factory uses automated production lines and strict quality control to produce high-reliability circuit boards at competitive aluminum plate prices.

How does PCB stackup affect heat?

The layer structure of a PCB controls how well it dissipates heat and shields signals. For aluminium metal core PCBs, the stackup typically follows this pattern:

Copper layer on top for components
Thin dielectric for thermal transfer
Thick aluminium base for heat sinking

This simplified layout boosts thermal flow. By reducing the thermal resistance between heat-generating components and the aluminium base, the heat escapes more efficiently.

A good PCB stackup design ensures low heat buildup, better EMI performance, and long-term reliability.

What is the difference between aluminum PCB and FR4?

FR4 PCBs use fiberglass-reinforced epoxy as the core. They’re cheap, widely used, and fine for low-power electronics. But they trap heat. When used in high-power circuits, the temperature rise can damage components.

Aluminum PCBs, on the other hand, replace the FR4 core with a metal core. This major change improves:

Heat transfer
Mechanical strength
Lifespan
Power capacity

Also, FR4 lacks the ability to dissipate heat efficiently, while aluminium PCBs can handle up to 10× better thermal flow. That’s why they dominate in LED lighting, automotive modules, and industrial drives.

What’s the thermal conductivity of aluminium core PCB?

The thermal conductivity of an aluminium core PCB depends on the dielectric layer and aluminium grade, but it usually ranges between 1.0 W/mK to 3.0 W/mK. Some high-end materials can reach up to 5.0 W/mK.

By comparison, FR4’s thermal conductivity is just 0.25 W/mK. That makes aluminium core PCBs around 4 to 20 times more effective at transferring heat.

Conclusion:

Aluminium core PCBs offer powerful thermal management, high durability, and compact design, making them ideal for modern electronics like LED lighting, power supplies, and automotive systems. Compared to traditional FR4 boards, they handle heat far more efficiently, ensuring longer device life and better performance.

Chip on Board LED Grow Light, COB LED PCB Manufacturer

Thursday, July 24th, 2025

Indoor gardening has seen a boom in recent years, especially with the rise of efficient grow light systems. Among these, the chip on board LED grow light—often known as COB LED grow light—has gained popularity for its superior performance. But behind every powerful COB grow light lies a well-designed circuit board that manages everything from heat to power distribution.

In this article, we’ll explore how COB LEDs work and how to design a COB LED PCB to reach better performance. Let’s keep reading.

What Is a Chip on Board LED Grow Light?

A chip on board LED grow light is a type of lighting system where multiple LED chips are mounted directly onto a single substrate or circuit board. Instead of using dozens or even hundreds of individual LED diodes (like in traditional SMD LED grow lights), a COB LED light packs high-intensity chips closely together.

The COB LED PCB (Printed Circuit Board) not only holds these chips but also plays a crucial role in:

Conducting electrical signals efficiently
Managing heat buildup
Supporting the light’s physical structure

So while most people focus on the “light,” professionals know that a high-quality COB LED grow light starts with a reliable, well-designed circuit board.

Advantages of COB LED in Grow Lights

Why are so many manufacturers and indoor growers switching to COB technology? Here are some reasons.

Full Spectrum Light

A COB LED grow light full spectrum covers all wavelengths needed for healthy plant growth, including red, blue, and white light. So that plants enable to thrive in every stage—from seedling to flowering—without changing the light source.

High Light Intensity

Because multiple chips are placed together, COB LEDs deliver stronger, more focused light. This can improve canopy penetration and boosts PPFD (Photosynthetic Photon Flux Density), meaning more usable light reaches your plants.

Energy Efficiency

Compared to older HID or fluorescent lighting, COB LEDs use less electricity and produce less heat for the same or better results.

Longer Lifespan

Fewer components, better thermal design, and robust build quality allow COB LEDs to last for 50,000 hours or more—if the PCB is properly designed.

Compact Design

With fewer components, COB grow lights are thinner, lighter, and easier to install—perfect for small grow tents or professional setups.

Factors That Affect COB LED Grow Light Price

The COB LED PCB cost higher than normal LED PCB, do you know why? Here are some factors we summarized for your information:

1. Wattage & Size: More powerful lights require larger boards, thicker copper layers, and more robust cooling solutions.

2. Spectrum Design: Adding UV or IR wavelengths, or fine-tuning the spectrum to specific plant types, often requires specialized LED chips and tailored PCBs.

3. Heat Management: Better thermal control means more expensive materials—like aluminum, copper, or even ceramic substrates—to handle higher heat loads.

4. PCB Material & Build Quality: Cheap PCBs may use thin copper or poor insulation, which can lead to early failures. Investing in a high-performance COB LED PCB ensures long-term reliability.

Why Customizing COB LED PCB Matters?

For most lighting brands, buying standard COB LED modules can feel like a quick solution. But this approach comes with limitations:

You can’t control LED layout or spectrum design.
You may struggle with heat management in compact fixtures.
You depend on another supplier’s quality control, which risks inconsistencies.
Your products may look and perform like every other generic grow light.

By choosing to customize your COB LED circuit board, you gain:

Full control over chip placement and power design
Optimized thermal performance with proper materials and layouts
Enhanced durability for longer-lasting lights
A chance to differentiate your product in the market with unique features

In short, the circuit board is where you gain your competitive edge.

Common Challenges in COB LED PCB for Grow Lights

Designing COB LED PCBs for grow lights isn’t just about putting LEDs on a board. There are critical challenges that require engineering expertise:

1. Overheating

High-power LEDs generate significant heat. Without proper thermal vias, heat sinks, and substrate materials, the board can overheat, shortening LED life.

2. Uneven Light Distribution

Poor chip placement can cause hot spots or dark areas in your grow tent, affecting plant growth.

3. Electrical Failures

Low-quality boards might use thin copper layers, poor soldering, or weak insulation—leading to power issues or early burnout.

4. Moisture Damage

Grow rooms are humid environments. Without protective coatings or water-resistant designs, PCBs can corrode or short circuit.

5. Compatibility Issues

Boards not designed for specific drivers or enclosures can cause assembly headaches or require costly redesigns.

How to Design COB LED Circuit Boards for Grow Lights?

When designing COB LED circuit boards for plant grow lights, three critical elements must be optimized: spectrum control, light intensity adjustment, and thermal management. Here are some tips that help you to design a COB LED circuit board:

1. Spectrum Matching

Select high-efficiency LED chips in red (660nm), blue (460nm), and far-red (730nm) wavelengths. Use high-density COB arrays to ensure full coverage of the effective photosynthetically active spectrum (400–780nm).

2. Light Intensity Control

Integrate dimmable circuits with adjustable output from 0–1000 μmol/m²/s. Enable smooth dimming to meet plant needs at all growth stages—from seedling to flowering.

3. Thermal Management

Use ENIG (Electroless Nickel Immersion Gold) surface finish and optimized heat paths. Pair the PCB with a die-cast aluminum housing for efficient heat dissipation. Ensure LED operating temperature stays below 50°C to prevent leaf burn.

4. Pad Design

Apply ENIG or gold plating for all bonding pads. Pad size should exceed chip size by 0.25–0.3mm to prevent misalignment or chip rotation.
