What does PCB aluminum-core mean?

A Aluminum-core PCBAlso known as Metal Core PCB (MCPCB) or PCB metal substrate (IMS PCB), is a special circuit board that uses the base layer of aluminum instead of traditional FR4 material. The aluminum core functions as a structural support and thermal conductor, disappearing efficiently from components such as LEDs or power electronics.

These boards usually consist of three layers: copper circuit layers, thermal conductive dielectric layers, and aluminum substrates. Unlike conventional PCBs, PCB Aluminum-core Excel in high power applications where heat management determines performance and long life. IMS PCB variant emphasizes the role of isolated dielectric layers in preventing electric shorts while maintaining optimal thermal transfers.

What is aluminum core PCB material?

Copper circuit layer ‘

• Form a conductive path for electrical signals
• Usually 1-8 oz (35-280old) copper foil

Dielectric layerâ € œThe layer

• Isolation electrically but thermally conductively
• Contains epoxy filled with ceramics (1-3 W/Mâ · K Thermal Condutivity)
• Hold  ‰ ¥ 3000V electric isolation

Aluminum baseâ € œThe

• Alloy 5052 or 6063 (100-220 W/Mâ · K Thermal Conductivity)
• Thickness 1.0-3.2mm for heat spread and mechanical support

What are the benefits of aluminum-core PCB?

• Increase thermal conductivity -Aluminium eliminates heat faster than FR4 or traditional ceramic substrates, reduce thermal voltage on components and increase long -term reliability.
• Mechanical power -The variety, vibration, and physical pressure, making it suitable for the automotive environment, industry, and high vibrations.
• Mild construction -Offering a balance of strength and weight loss compared to alternative core-cores, helping portability in consumer electronics.
• Cost efficiency -Cayed materials and production lower than copper -based PCB, ideal for mass production projects that are sensitive to costs.
• Dimensional stability – Minimum expansion/contraction under temperature fluctuations ensures the integrity of consistent solder joints and component alignment.
• Simple cooling system -Reducing dependence on external heatsinks or fans by utilizing direct metal-to-component heat transfer.

What type of aluminum-core PCB?

Single -layer aluminum pcb:

• One -sided circuit with aluminum nucleus as a base layer, ideal for basic thermal management in LED lighting or power module.

Aluminum pcb double layer

• Two -sided circuit with aluminum substrate between layers, allows compact design for motor control or automotive electronics.

Multi-layer aluminum PCB

• The layer stacked with an integrated aluminum nucleus into an internal position, the density of the balance circuit and thermal performance in high power application.

When to use an aluminum PCB?

Application Aluminum-core PCB:

• LED lighting is high – Managing heat in street lights/headlights to prevent LED degradation.
• Automotive power system – Handling vibration/heat in engine control or battery module.
• Compact power module – Activate a solid DC/DC converter without external cooling.
• Industrial Motor Control -Stabilize high -current transistors in the factory drive.
• Outdoor electronics – Refuse humidity/UV in solar inverters or weather sensors.
• Thermal needs that are sensitive to costs – Budget/Performance Balance in Consumer Fillers/Adapters.
• Medical instrumentation – Maintaining the accuracy of temperature in a diagnostic/imaging device.

The difference between the core of copper vs aluminum core pcb

Here are 8 most important differences between copper core and aluminum core PCB:

• Copper Core: Weight (~ 8.96 g/cmâ³)
• Aluminum Core: Light (~ 2.7 g/cmâ³), better for portable devices

Feeâ € œ

• Copper Core: More expensive (~ 3-5x aluminum)
• Aluminum Core: More cost effective

Thermal Expansion ‘

• Copper Core: Matches the copper trail
• Aluminum Core: Higher CTE mismatch requires a careful design

Applicationâ € œ

• Aluminum Core: Easier for machines and processes

How to optimize your thermal design to achieve efficient heat dissipation?

• Select a high thermal conductivity substrate -The priority of aluminum (200-250 W/Mâ · K) or copper (380-400 W/Mâ · K) Core above FR4 to directly distribute heat from the components.
• Position the high power component near the base of the metal – Place the mosfet, LEDs, or power transistors directly with the substrate to minimize the thermal resistance pathway.
• Expand the surface area for radiation cooling – Integrate fins, open metal bearings, or expanded substrate parts to increase heat dissipation through air contact.
• Apply thermal interface (TIMS) material -Use silicone pads, oil, or film replace the phase to remove air gaps between components and substrates, reduce thermal resistance by 30-50%.
• Air flow or active cooling channel design -Make a ventilation path or install a low profile fan to direct the flow of air over the heat zone, important for a closed system or high-temperature-temperature environment.
• Validation with imaging and thermal simulation – The prototype test uses an infrared camera under operational load and design improvement based on hotspot analysis.
