How to Reduce Costs Without Compromising Medical LED PCB Quality?‌

Below are practical strategies to achieve this balance:

Optimize PCB Layer Count‌

Reduce layers where possible by simplifying circuit layouts. Use advanced routing techniques like HDI (High-Density Interconnect) to maintain functionality in fewer layers, lowering material and fabrication expenses.

Standardize Component Sizes and Footprints

Design with widely available, off-the-shelf components (e.g., 0603 or 0805 packages) to avoid costly custom parts. Ensure footprints match industry standards to streamline assembly and reduce sourcing delays.

Leverage Design for Manufacturability (DFM)‌

Collaborate early with manufacturers to identify cost-saving design adjustments. Eliminate unnecessary features like oversized solder pads or non-critical via fills that add complexity without value.

Choose Cost-Effective and Compliant Materials

Select substrates (e.g., FR4 instead of ceramic for non-high-power LEDs) that meet thermal and safety requirements without over-specifying. Verify alternatives retain biocompatibility and sterilization resistance.

Batch Prototyping and Production‌

Consolidate multiple design iterations into a single prototyping batch to minimize setup costs. For low-volume medical projects, partner with manufacturers offering pooled production runs with other clients.

Negotiate Long-Term Supplier Contracts‌

Secure volume-based pricing for recurring materials like copper-clad laminates or solder masks by committing to long-term agreements with trusted suppliers.

Implement Automated Testing Early

Integrate automated optical inspection (AOI) and in-circuit testing (ICT) during prototyping to catch defects early. Reducing rework in later stages lowers overall costs.

Simplify Assembly Processes

Design panels with standardized sizes to maximize panel utilization during assembly. Avoid mixed-technology boards (e.g., combining SMT and through-hole) unless necessary to reduce labor costs.

Prioritize Functional Over Aesthetic Finishes‌

Use HASL (Hot Air Solder Leveling) instead of ENIG (Electroless Nickel Immersion Gold) for non-critical connections. Reserve premium finishes only for high-reliability areas like edge connectors.

Reuse Validated Circuit Blocks

Modularize designs by recycling pre-tested circuit blocks (e.g., power regulators or EMI filters) from previous projects. This minimizes redesign efforts and accelerates certification.

What is PCB Heat Sink Pad? How to Design a Thermal Relief Pad?

Monday, April 21st, 2025

What is PCB Heat Sink Pad?

In high-power electronics, heat is a persistent issue. When left unmanaged, it leads to failure, reduced life span, or poor performance. One of the smart ways to address this is by using a PCB heat sink pad. Sometimes referred to as thermal relief pads, these are conductive areas on a printed circuit board that channel heat away from components. They play a critical role in thermal management, especially in compact and high-density board layouts.

These pads are often seen near power components, processors, or any part prone to heat buildup. By connecting to thermal vias or copper pours, they guide excess heat to ground or large copper areas. Thermal pads improve overall stability without the need for bulky external coolers. A well-designed thermal pad saves cost, space, and ensures better thermal cycling performance.

Importance of PCB Heat Sink Pad

The importance of a PCB heat sink pad lies in its ability to support both thermal and electrical performance. As devices get smaller and more complex, the demand for thermal balance grows. Traditional cooling methods, like fans or heatsinks, aren’t always viable in a tight layout. That’s where these pads step in.

They serve as an internal heat escape path. By reducing the junction temperature of critical parts, the heat sink pad ensures devices function at optimal levels. Without it, hot spots develop, possibly leading to delamination or component drift. In automotive, aerospace, or industrial environments, this can’t be ignored.

Another key advantage is manufacturing. During reflow soldering, thermal pads help maintain consistent heating. This improves solder joint quality, avoiding cold joints or solder bridges.

What Is the Function of a PCB Heat Sink Pad?

The core function of a PCB heat sink pad is to pull heat away from the component body. This prevents overheating and promotes reliability. A pad usually sits beneath a hot-running device and connects to a ground or power plane through thermal vias. These vias act like vertical pipes that carry heat down to larger copper surfaces.

Besides thermal performance, the pad also serves mechanical purposes. It supports the component body, helps with proper alignment during placement, and aids in reflow stability. In power ICs, LEDs, and RF modules, such a pad is more than a convenience—it’s a necessity.

Often placed under QFNs, D-Pak, or Power MOSFETs, thermal pads are essential for packages where direct contact to the PCB is required for heat dissipation.

PCB Thermal Pad vs Heatsink

Understanding the thermal pad vs heatsink comparison helps in design decisions. A thermal pad (on PCB) is a built-in copper area, often plated and connected via thermal vias. It is internal and does not add extra height to the device. It’s subtle, efficient, and passive.

A heatsink, on the other hand, is a physical attachment—usually a metal block or finned structure—mounted on top of the component. It dissipates heat through air convection. While highly effective, heatsinks increase weight and require space. They may also need fasteners or thermal paste for better performance.

In low to medium-power circuits, thermal pads do the job silently. When current levels increase or the ambient conditions are harsh, heatsinks may be added. However, both solutions often work together. A pad draws the heat from the chip, and the heatsink then transfers it to the air.

Why Do We Need Thermal Pad on PCB?

We need thermal pads on PCBs to manage heat efficiently within confined board layouts. As chips grow more powerful and boards become smaller, heat density rises. Left unchecked, this can stress the materials, warp the PCB, or trigger thermal shutdowns in sensitive ICs.

Thermal pads provide a compact and cost-effective solution. Unlike external cooling systems, these pads are part of the board design. They reduce the thermal resistance between the component and the ground plane, making heat transfer faster and more efficient.

In LEDs, they stop lumen drop due to temperature spikes. In CPUs or RF amplifiers, they prevent drift in performance. Across industries, from smartphones to satellites, thermal pads are silent protectors against damage caused by thermal fatigue.

Design Consideration of Thermal Relief Pads on PCB

The design of thermal relief pads is not just about placing a copper square under a part. It demands precision. Several factors shape the design.

1. Pad Size: The area should match the component’s thermal tab. Oversized pads can cause solder wicking; undersized ones fail to transfer heat efficiently.

2. Vias Count and Diameter: Vias enhance heat transfer. Placing multiple small vias (0.3mm diameter with 6+holes) within the pad connects it to inner or bottom layers. These must be filled or tented to avoid solder leakage.

Design Consideration of Thermal Relief Pads on PCB

3. Copper Weight: Thicker copper layers enhance thermal conduction. A 2oz or 3oz copper layer works better than standard 1oz in high-heat zones.

4. Solder Mask Clearance: The pad must be free from mask to allow full thermal contact.

5. Connection to Planes: The pad should tie to ground or power plane, depending on the circuit. Use thermal relief spokes when needed to balance heat dissipation and solderability.

6. Component Package Type: Each package, whether QFN or TO-263, demands unique pad sizing and via patterns. Manufacturer datasheets offer recommended layouts—follow them closely.

When to Use Thermal Relief PCB?

Using a thermal relief PCB becomes necessary in several scenarios. One key use is in multilayer boards where copper planes absorb too much heat. Without thermal relief, soldering becomes difficult as heat spreads too quickly. This leads to cold joints or poor wetting.

Thermal reliefs help balance the heat flow. They allow soldering while still ensuring strong thermal performance. Another situation arises with through-hole components connected to large copper areas. Thermal relief spokes prevent the pad from acting like a heat sink during soldering.

Power applications like inverters, motor controllers, and regulators benefit from thermal relief PCBs. So do high-brightness LED arrays. In RF boards, where impedance matters, thermal pads also stabilize the electrical response by providing consistent grounding.

Use them when heat buildup could impair function or reduce board life. Proper relief design improves both manufacturing and operational performance.

The main function of a metal core PCB is to provide higher thermal conductivity, which is especially beneficial in applications requiring efficient heat dissipation like LED lights. In a typical PCB, heat can accumulate and negatively affect the performance and lifespan of electronic components. However, the metal core serves as an effective medium for channeling heat away from sensitive areas, optimize the operation and longevity of the circuit.

Metal core PCBs are made with materials like aluminum or copper that allow for effective thermal transfer. They are primarily used in high-power applications, where managing heat is crucial to maintaining the functionality of devices.

What is MCPCB Core Made of?

The core of a Metal Core PCB is typically composed of a metal material that has superior thermal conductivity properties. The most commonly used metals are aluminum and copper, with aluminum being the most popular due to its cost-effectiveness and excellent thermal performance.

Aluminum: Aluminum is often the metal of choice for MCPCB cores because it offers a combination of high thermal conductivity, light weight, and affordability. Its relatively low cost compared to copper makes it an attractive option for mass production, especially in consumer electronics and lighting applications.

What Are the Materials Used in Metal Core PCB?

The materials used in Metal Core PCBs are carefully selected to ensure high performance and reliability. The primary materials include:

Base Material (Metal Core): As mentioned earlier, the core of the PCB is typically made of aluminum or copper. The choice of metal directly impacts the thermal conductivity and cost-effectiveness of the PCB.
Insulating Layer: Above the metal core, there is an insulating layer that electrically isolates the metal core from the copper traces on the PCB. This layer is typically made from a thermally conductive dielectric material, such as epoxy resin or fiberglass. The insulating layer ensures that the metal core doesn’t short-circuit the copper traces while still allowing for efficient heat transfer.
Copper Foil: The copper foil is used to create the circuit traces. Copper is chosen for its excellent electrical conductivity and reliability. The copper is etched to form the required circuit pattern, allowing electrical signals to flow seamlessly through the PCB.
Solder Mask: The solder mask is a protective layer that covers the copper traces to prevent oxidation and improve durability. It also provides electrical insulation to prevent short circuits and ensures that components are properly soldered.
Silkscreen Layer: The silkscreen layer is used to print labels, markings, and other necessary information onto the surface of the PCB. This layer aids in component placement during assembly and provides identification for troubleshooting.

Together, these materials form a Metal Core PCB that is capable of efficiently managing heat while ensuring electrical performance and durability.

How Thick is a Metal Core PCB?

The thickness of a Metal Core PCB depends on various factors, including the application’s thermal and mechanical requirements. Typically, the total thickness of a metal core PCB ranges from 1.6 mm to 3.2 mm, but it can vary depending on the design and intended use.

Core Thickness: The metal core itself typically ranges from 0.3 mm to 2.0 mm in thickness. Thicker cores provide better heat dissipation but may increase the overall cost of the PCB.
Overall PCB Thickness: The overall thickness, including the copper traces, insulating layer, and solder mask, can vary depending on the complexity of the design and the type of components being used. For high-power applications, a thicker PCB may be necessary to ensure adequate heat management and mechanical strength.

How is a PCB Manufactured Step by Step?

The manufacturing of a Metal Core PCB (MCPCB) is a highly specialized process that involves several crucial steps to ensure thermal efficiency, reliability, and electrical performance. Below is a detailed breakdown of each step involved in the MCPCB manufacturing process.

1. Design and Layout Preparation

The first step in the manufacturing of an MCPCB is the design phase. Engineers and designers create the PCB layout, including the placement of components, traces, vias, and pads. This layout must consider factors like thermal management, electrical conductivity, and mechanical strength. The design is usually done using specialized software like AutoCAD or Altium Designer.

In the case of MCPCBs, the layout also includes specific considerations for the metal core, insulating layer, and the heat dissipation needs of the application. The thermal conductivity of the material, as well as the required heat dissipation paths, are factored into the design.

2. Core Material Selection

The next step involves selecting the appropriate core material. For MCPCBs, the core is typically made from metal, usually aluminum or copper. The choice of metal affects both the thermal performance and cost of the PCB.

Aluminum is lightweight, cost-effective while copper has superior thermal conductivity compared to aluminum, and is often used in more demanding applications that require exceptional heat dissipation, such as high-power electronics or automotive applications.

3. Insulating Layer Preparation

Next, an insulating dielectric material is applied to the metal core. This insulating layer is crucial for electrically isolating the metal from the copper traces while still enabling efficient heat transfer. The material used for this layer is typically a thermally conductive resin or fiberglass composite.

The insulating layer’s thickness depends on the requirements of the circuit. It must be thick enough to provide electrical isolation, yet thin enough to allow heat to pass through it efficiently. This layer is typically applied as a thin film or laminate and is then bonded to the metal core using heat and pressure.

4. Copper Foil Lamination

Once the insulating layer is in place, a layer of copper foil is laminated onto the surface. The copper foil is typically bonded to the insulating layer under high pressure and temperature.

Thicker copper foils are used for high-power applications, while thinner foils are sufficient for low-power circuits.

5. Circuit Etching

After the copper foil has been applied, the next step is to etch the circuit pattern. This is done using a chemical etching process, where the unwanted copper is dissolved away, leaving only the copper traces that form the electrical pathways.

The process including apply a photoresist film onto the copper, and then it is exposed to UV light through a mask. The board is then exposed to a chemical solution that etches away the exposed copper, leaving behind the desired circuit pattern.

6. Drilling and Plating

Once the copper traces have been etched, the next step is to drill holes for vias and component leads. Vias are used to establish electrical connections between different layers of the PCB, if applicable. Drilling is done with precision machinery to ensure the holes are accurately positioned.

After drilling, the holes are plated with copper to create electrical connections. The plating process involves depositing a thin layer of copper onto the walls of the drilled holes using an electroplating process. This creates the necessary conductive pathways for signals to travel through the different layers of the PCB.

7. Solder Mask Application

Next, a solder mask is applied to the PCB. The solder mask is a protective layer that prevents oxidation, protects the copper traces from damage. The solder mask is typically a green-colored epoxy-based material, although other colors can be used depending on the customer’s requirements, like red, black, white. Metal core PCB always use white solder mask to gather a good light reflection.

8. Silkscreen Printing

After the solder mask is applied, a silkscreen layer is used to print component labels, markings, and other important information on the surface of the PCB. This is helpful during assembly, as it indicates the proper locations for components to be placed.

The silkscreen printing is typically done using a screen printing process, where ink is pushed through a mesh screen to form the desired markings. Generally, the white solder mask with a black silkscreen, and black solder mask with a white silkscreen.

9. Inspection and Testing

Once the MCPCB has undergone the necessary manufacturing steps, it is thoroughly inspected for defects and tested for functionality. The metal core PCB always must pass three inspection – electrical, thermal, and mechanical requirements.

10. Final Assembly

The final step in the MCPCB manufacturing process is the assembly of electronic components onto the PCB. This involves placing components like resistors, capacitors, LEDs, and other active and passive elements onto the board and soldering them in place.

Component placement is typically done using automated machinery to ensure accuracy and speed. Once the components are placed, they are soldered onto the pads using either wave soldering or hand soldering, depending on the complexity of the design.

11. Quality Control and Shipping

Once the assembly is complete, the final MCPCB undergoes a final functional inspection and quality control check to ensure that it meets the required specifications. The finished product is then packaged and prepared for shipping to customers.

During the quality control phase, the board is examined for any signs of poor soldering, component misplacement, or other issues. If the board passes all inspections, it is ready for shipment.

Metal Core PCB Applications

Metal Core PCBs are used in a variety of industries, thanks to their exceptional thermal management capabilities. Common applications include:

LED lighting like pool lighting, UV led, led car lighting, high bay light, stair light, etc.
Power supplies
Automotive
Sensors
Electronic control units
Telecommunications
Consumer Electronics
Computers
Smartphones
Televisions

FAQs

1. Can I design the dielectric layer much thinner on MCPCB?

Yes you can. Thinner dielectric layer has better thermal conductivity, but also has a lower breakdown voltage

2. Can you do gold immersion finish on double sided MCPCBs?

Yes, we can do gold immersion finish on double sided MCPCB, but the price will be less competitive than HASL-LF.

3. Top 6 factors affecting the final cost of MCPCB?

1) Board Dimention: For the non-rectangular board, we will calculate the longest two sides, for example, the circle is calculated according to the diameter.

Apply thermal pads, pastes, or phase-change materials between the PCB and heat sinks. These fill microscopic gaps, ensuring efficient heat transfer.

7. Optimize Power Distribution

Reduce resistive losses by widening traces connected to high-current LEDs. Use star topologies or dedicated power planes to minimize voltage drops and heat generation.

8. Enable Forced Air Cooling

For high-density LED cubes, install small fans or blowers to enhance airflow. Position them to direct air across the PCB surface or through heat sink fins.

9. Monitor Temperature with Sensors‌

Embed temperature sensors near hotspots. Use feedback to dynamically adjust brightness or activate cooling systems when thresholds are exceeded.

10. Test and Iterate

Validate thermal performance using infrared cameras or thermocouples. Adjust copper pour areas, via placement, or cooling methods based on real-world data.

DOB LED vs. COB LED vs. SMD LED: 3 Options for LED PCB

Thursday, April 17th, 2025

DOB Full Form in LED

DOB full form in LED is “Driver on Board.” In LED lighting, this means the driver circuit is built directly onto the LED board. There’s no need for a separate external driver. This configuration is based on the consideration that LED drivers have been dominantly designed as switching mode power supplies.

A DOB LED PCB is a neat package. It has the LEDs, power regulation circuit, and other supporting components all mounted on a single board. This includes rectifiers, surge protectors, constant current regulators, and sometimes capacitors to stabilize the current.

Because the dob led driver circuit is built-in, these boards are usually smaller and more lightweight. Most use aluminum base PCBs, which help draw heat away from the components to improve lifespan.

DOB LED vs. COB LED vs. SMD LED: 3 Options for LED PCB Board

What Is LED Driver?

Simply put, a LED driver is a part that mainly used to control the power going to your LEDs. LEDs work best when they get a consistent current. A driver makes sure the current stays steady, even when the input voltage changes.

Traditional LED lighting uses an external driver. It converts AC (from your wall) to DC (what the LEDs need). But in the LED DOB approach, this conversion happens right on the board. That’s why DOB lights don’t need external drivers.

However, some large-scale lighting systems still prefer external drivers for better thermal control and longer lifespan. For smaller applications, dob led lights are a good choice due to the convenience.

LED Bulb DOB Circuit Diagram

A basic led bulb dob circuit diagram includes:

Input terminals (AC supply)

Bridge rectifier

Filtering capacitor

Constant current IC or regulator

LED array

Here is a typical diagram of DOB LED circuit:

How Does DOB LED Driver Circuit Work?

The DOB LED driver circuit operates through several key functional blocks, including input overvoltage protection, rectification and filtering, current limiting, and PWM dimming.

1. Input Overvoltage Protection

The DOB LED circuit includes an overvoltage protection mechanism to handle power surges caused by lightning or sudden spikes from the mains. When a DC voltage is applied across the “+48V” and “GND” terminals, current first flows through resistor R1 to limit the surge. If the voltage rises beyond a safe level, the current through R1 increases, causing a voltage drop. Once this drop exceeds 1W, the protection system activates—R1’s resistance instantly increases to an extremely high value, effectively blocking the current and shielding the +48V input line from damage.

2. Rectification and Filtering Circuit

When the input is AC power, a bridge rectifier converts the alternating current into direct current. This DC output passes through the rectifier for polarity protection, preventing damage from reversed connections. Components like capacitors C1 and C2, along with inductor L1, smooth out the ripples and produce a stable DC voltage.

3. Current Limiting Circuit

LEDs require stable current to operate efficiently and avoid damage. That’s why DOB circuits use a current-limiting mechanism, typically based on either resistors or constant current sources. A constant current driver is commonly preferred because it maintains consistent brightness across varying input voltages and temperatures, helping extend LED life and performance.

4. PWM Dimming Control

To control brightness, DOB LED circuits often use PWM technology. By adjusting the duty cycle of the PWM signal, the average current through the LED changes, which alters the brightness. This is usually done by modifying the voltage at the top end of the feedback resistor, which in turn regulates the current through the LED.

DOB LED PCB Advantages and Disadvantages

Advantages:

Fewer components: With no external driver, the whole assembly becomes simpler.
Cost-effective: Fewer parts and simpler design reduce production costs.
Space-saving: The integrated design is ideal for compact lighting like LED bulbs or tubes.
Lightweight: No bulky driver means less weight.
Easy to install and replace: Just plug and go. No extra wiring or enclosures.

Disadvantages:

Limited in high-wattage systems: Integrated drivers can heat up quickly and struggle with larger currents.
Heat management is critical: Without good cooling, performance drops over time.
Lifespan is tied to board quality: A poorly designed dob led driver circuit may shorten LED life.
Not suitable for dimming: Most DOB circuits don’t support dimming out-of-the-box.

Despite the challenges, dob led lights work well in most indoor environments. They offer an easy plug-in lighting solution without the need for complex wiring.

What Is DOB LED Used For?

So, where do you use a dob led? Pretty much everywhere light is needed in a simple, cost-effective form. You’ll find dob led pcbs in:

LED light bulbs
Tube lights
Panel lights
Garden lights
Wall lamps
Street lamps (low wattage)

Because the entire system is compact, manufacturers often choose DOB for plug-and-play lighting. A dob led light is cheaper to make and easier to sell in volume. The efficiency and simplicity make DOB ideal for home lighting, budget projects, and commercial interiors.

What Is COB LED PCB?

COB, which stands for “Chip on Board.” In this case, multiple LED chips are mounted directly onto the PCB with very little space between them. This setup creates a dense, bright light source. The PCB itself is usually aluminum-based. The close grouping of chips gives the COB LED PCB its signature even, shadow-free glow. COBs are used in spotlights, floodlights, and other high-intensity applications.

Unlike dob led, a COB PCB doesn’t have a driver built-in. It needs an external LED driver to control current and voltage.

Features of COB LED PCB

High density of LEDs on one board
Excellent brightness and high lumen output
Smooth and even light beam
Strong thermal management (especially with aluminum core PCBs)
Compact design for high-power fixtures

COB designs work well in lighting products where powerful and uniform light is needed.

COB LED PCB Advantages and Disadvantages

Advantages:

Brighter output: More chips in one place = more light.
Compact but powerful: Ideal for high-performance lighting in small sizes.
Low glare: Even distribution of light reduces harsh spots.
Thermal efficiency: Designed for good heat dissipation.

Disadvantages:

Needs an external driver: That adds cost and space requirements.
Not flexible: Fixed shape and size limit design options.
Slightly higher cost: More complex manufacturing process.

Still, for strong lighting needs—like industrial or architectural setups—COB wins over dob led in brightness and beam quality.

What Is SMD LED PCB?

SMD stands for Surface Mounted Device. These are individual LED chips mounted directly onto the surface of the board. Unlike COB, where chips blend into one source, SMDs remain separated.

Common package sizes of SMD LED include 3528, 2835, and 5050 SMD chips. Each number relates to the dimensions in millimeters. These chips are popular for flexible LED strips, signage, and backlit displays.

A smd led pcb often supports RGB functions. That means each LED can emit different colors, which is useful for digital billboards, decorative lights, and custom control systems.

Features of SMD LED PCB

High flexibility in design layout
Small and lightweight LEDs
Available in different color options (RGB & RGBW)
Can be used on both rigid and flexible boards
Suitable for decorative and general-purpose lighting

SMD LED PCB Advantages and Disadvantages

Advantages:

Design freedom: Great for custom layouts and creative shapes.
RGB ready: Many SMDs support multi-color output.
Lower cost: Ideal for mass production.
Good performance: Bright, efficient, and adaptable.

Disadvantages:

Less heat-resistant: Not as efficient as COB in thermal handling.
May require more circuitry: For full color and control, extra components are needed.
Light is more scattered: Doesn’t provide a focused beam like COB.

PCB Aluminium Substrate, Aluminum PCB Board for LED

Thursday, April 17th, 2025

When it comes to reliable and advanced PCB solutions, Best Technology leads the way. With more than 18 years in the industry, we provide custom circuit board manufacturing for global clients. From prototype to volume production, we help you build better products with very good heat dissipation and military-grade quality. Our strength lies in metal-based PCBs, especially pcb aluminium substrates. These are widely used in LED, automotive, telecom, and power industries. With precision equipment and a strict quality system, we ensure high-performance boards that meet your needs.

What Is a PCB Aluminium Substrate?

A PCB aluminium substrate is a type of metal-based printed circuit board. (MCPCB) It uses aluminum as its base material instead of traditional FR4. This base supports layers of dielectric, and copper circuits. Aluminum PCBs offer strong heat dissipation and structural support compared with normal rigid PCB. The aluminum base acts as a heat sink. This makes the substrate ideal for high-power or thermally sensitive applications. In simple terms, it’s a PCB built on aluminum rather than fiberglass.

PCB Aluminium Substrate, Aluminium PCB Board for LED

Performance of Aluminium Substrate PCB in LED

Aluminum substrate PCBs are the backbone of today’s LED lighting systems. Their ability to manage heat is the most critical factor. When LEDs operate, they generate a lot of heat at the junction point. If that heat isn’t removed quickly, the LED’s brightness fades, and its lifespan shortens. Using an aluminum board for LED, we can get these benefits:

Efficient heat dissipation: The aluminum metal base acts as a built-in heat sink, pulling heat away from the LED source and spreading it across the board.
Improved reliability: By reducing thermal stress, the board helps extend the lifespan of each LED component. That means longer-lasting light and less need for replacement.
Stable light output: Overheating causes LEDs to dim. Aluminum PCBs maintain the thermal balance so that brightness stays consistent. Whether it’s a street lamp or a small indoor fixture, aluminum PCBs deliver stable operation.
Compact design: Since aluminum boards manage heat on their own, there’s no need for bulky external cooling systems.
Cost-effective: Although slightly more expensive than FR4, their longer lifespan and lower maintenance needs make them a better investment for lighting manufacturers.

6061 vs. 5052 vs. 1060 Aluminum Substrate

In the aluminum PCB manufacturing, the common aluminium substrates that manufacturers always use are 6061 aluminum substrate, 5052 aluminum substrate and 1060 substrate. All of them are aluminum allay, but the compositions and purity are different, so that the performance different too.

5052 aluminum sheet belongs to Al-Mg alloy, the main alloying element is magnesium, which has a content of 2.2% ~ 2.8%. In addition, it also contains a small amount of chromium (0.15%-0.35%) and other elements. The addition of which is intended to improve the strength and corrosion resistance of the alloy. 6061 aluminum sheet is Al-Mg-Si alloy, in addition to magnesium (0.8%-1.2%) and silicon (0.4%-0.8%) as the main alloying elements, copper (0.15%-0.4%) and zinc (less than 0.25%) are also added. 1060 aluminum material belongs to pure aluminum sheet, with an aluminum content of more than 99.6%, and almost no other alloying elements. Different alloy components form the basis of the different performances of these aluminum substrates. Below is a table comparison show the differences between each of them:

Property	6061 Aluminum	5052 Aluminum	1060 Aluminum
Composition	Magnesium & silicon alloy	Magnesium alloy	Pure aluminum (≥99.6%)
Thermal Conductivity	Moderate (150 W/m·K)	High (160 W/m·K)	Very high (≈237 W/m·K)
Strength of Extension	290MPa	215MPa	Low
Hardness	95HB	65HB	30HB
Elongation	10-18%	12-25%	5%
Formability	Low	High	High
Corrosion Resistance	Good	Excellent	Good
Common Uses	Structural parts, high-load PCBs	LED lights, flexible designs	High heat-dissipation PCBs
Cost	Higher	Medium	Lower

(6061 vs. 5052 vs. 1060 Aluminum Substrate)

So how to choose the suitable substrate for your aluminum PCB board? Follow this rule:

Choose 1060 if your project needs maximum thermal conductivity.
Choose 5052 if flexibility and corrosion resistance are more important.
Choose 6061 if you need strength and rigidity for heavy-duty PCBs.

What Is the Dielectric Layer of Aluminum PCB?

Aluminum substrate is generally composed of three layers: circuit layer (copper foil), dielectric layer and metal base. The dielectric layer is located between the circuit layer and the metal base layer, which acts as insulation and heat conduction. It is a polymer filled with high thermal conductivity and high insulation ceramic powder, make it is an ideal material with non-conductive but heat-conductive.

single sided PCB aluminium substrate structure

This dielectric layer has good heat conduction properties (thermal conductivity up to 3.0W/m-K), it is the key to thermal performance. It allows heat to pass from the copper to the aluminum while keeping them electrically isolated. The dielectric must have low thermal resistance and high breakdown voltage. Materials used often include ceramic-filled epoxy or polyimide. These support thermal conductivity while maintaining safety.

What Is the Difference Between FR4 and Aluminum PCB?

FR4 PCBs use fiberglass as a base. They are cheaper and more common. But they are poor at dissipating heat. They also deform more under thermal stress. Aluminum PCBs, on the other hand, handle heat much better. The aluminum pcb thermal conductivity is usually between 1.0 to 3.0 W/m·K. In contrast, FR4 is less than 0.3 W/m·K. That means aluminum PCBs can move heat away much faster. Here we listing the main differences between two of them:

Feature	FR4 PCB	Aluminum PCB
Base Material	Fiberglass-reinforced epoxy	Aluminum metal
Thermal Conductivity	≈0.3 W/m·K	1–3 W/m·K
Heat Dissipation	Poor	Excellent
Mechanical Strength	Moderate	High
EMI Shielding	Weak	Strong
Cost (under the same design complexity situation)	Lower	Slightly higher
Use Cases	Consumer electronics, PCs	Mainly used in led lights, automotive, power modules
Thickness Options	0.10mm, 0.12mm, 0.15mm, 0.20mm, 0.25mm, 0.30mm, 0.40mm, 0.50mm, 0.60mm, 0.80mm, 1.0 mm, 1.2 mm, 1.6mm, >=2.0 mm	0.30mm, 0.40mm, 0.50mm, 0.60mm, 0.80mm, 1.0 mm, 1.2 mm, 1.6mm, 2.0 mm, 2.4mm, 3.0mm (exclude copper)
Weight	Much lighter	Heavier but lighter than copper pcb
Environment Tolerance	Lower heat resistance	Withstands high temperatures

How Do You Make Aluminium PCB?

The manufacturing process of aluminum PCB is almost the same as normal FR4 PCB, except the lamination process of dielectric layer, aluminum and copper. This also is the biggest manufacturing difficult that faced by manufacturers, especially for multi-layer aluminum PCB. For the single & double sided aluminum PCB, the aluminum substrate we purchased from the manufacturers are laminated with dielectric, so we do not need to laminate again. In addition to this, the manufacturing process of aluminum PCB with insulated hole and without insulated hole are different.

Single-sided Aluminum PCB without insulated hole:

Cutting raw material (substrate laminated with dielectric layer) — Circuit layer generation (D-E-S) — Solder Mask – Silkscreen — Surface Treatment — Stripping — Drill Holes — Outline (V-cut – Routing – Die Punching) — QC — Package & Delivery

Single-sided Aluminum PCB without insulated hole

Single-sided Aluminum PCB with insulated hole:

Cutting raw material (substrate without laminated with dielectric layer) — Drill larger holes — Filled resin with holes — Lamination (dielectric layer + copper + aluminum base) — Circuit layer generation (D-E-S) — Solder Mask – Silkscreen — Surface Treatment — Stripping — Drill Holes — Outline (V-cut – Routing – Die Punching) — QC — Package & Delivery

Manufacturing Difficulties of Aluminum PCBs

Working with aluminum is not the same as working with FR4. It brings challenges, especially for a professional aluminum PCB manufacturer.

1. Mechanical Processing

Drilling holes on aluminum PCBs is possible, but the inner walls and board edges must be completely free of burrs. Even a slight burr can cause the board to fail the high-voltage test. Milling the outline is also quite difficult. The milling cutter used for FR4 PCB board has a relatively low hardness, while the milling cutter used for aluminum substrate has a high hardness. During the processing, the milling cutter for fiberglass board production has a high speed, while the milling cutter for aluminum substrate production has a speed at least 2/3 slower. As an alternative, punching with high-precision dies is often used—but die making requires exceptional skill, making this one of the main challenges in aluminum PCB manufacturing.

After punching, the edges must be clean and smooth, without any burrs or damage to the solder mask along the edges. Most factories use compound dies. Holes are punched from the circuit side, and the outline is punched from the aluminum side. This requires specific techniques, such as upward shearing and downward pulling during punching. Even after punching, the board’s warpage must be strictly controlled and should remain under 0.5%.

2. Protecting the Aluminum Surface During Processing

The aluminum base must remain completely free of scratches throughout the entire production process. Any direct contact with hands or chemicals can cause surface discoloration or oxidation, which are absolutely unacceptable. In many cases, re-polishing the aluminum surface is not allowed by customers. So, avoiding even the slightest damage to the aluminum layer is another major difficulty in the production process.

Some manufacturers use surface passivation treatments, while others apply protective films before and after hot air solder leveling (HASL). There are countless tricks and methods used to keep the surface clean—every factory has its own unique way of doing it.

3. High-Voltage Testing Requirements

For telecom power supply boards, 100% high-voltage testing is often mandatory. Some clients require DC testing, while others specify AC, typically at 1500V or 1600V for durations of 5 to 10 seconds. Every single board must pass this test.

Even the smallest contamination on the surface, burrs on holes or edges, jagged traces, or damage to the insulation layer can lead to arcing, leakage, or dielectric breakdown during testing. Boards that show signs of delamination or bubbling during the test are automatically rejected.

Despite these, trusted manufacturers like Best Technology handle it well. Our experience helps solve such problems early in the process.

How Much Does Aluminum PCB Cost?

Many factors influence the pcb aluminium substrate price. These include:

Aluminum grade (6061, 5052, or 1060)
Thickness of copper and base layer
Board size and layer count
Surface finish type
Quantity ordered
Special design features (e.g., thermal vias, contours)

In general, aluminum PCBs cost more than FR4 boards. But for heat-sensitive designs, the added cost pays off in reliability.

For instance, a basic one-layer aluminum PCB may start from $1.0–$5.0 per unit in bulk. Complex designs with multi-layers or special finishes can go higher.
