Also known as MCPCB (Metal Core PCB), an aluminum PCB board is composed of a copper circuit layer, a thermal dielectric layer, and an aluminum base. With excellent heat dissipation and superior mechanical stability, aluminum core PCBs are widely used in high-performance applications such as LED lighting, automotive electronics, and power modules.
Commonly used base materials include 6061, 5052, and 1060 aluminum, while optional substrates such as copper, stainless steel, iron, and silicon steel can be selected to meet specific thermal and structural requirements. As an experienced aluminum PCB manufacturer in China, WeiYuanDa PCB provides customized aluminium clad PCB solutions that ensure reliability, durability, and cost efficiency for global OEMs.

Single-Layer Aluminum PCB:
The process includes material preparation, lamination, circuit generation, drilling, solder mask application, silk screening, surface treatment, punching and board separation, testing, final inspection, packaging, and shipping.
Double-Layer Aluminum PCB:
In addition to the steps above, double-layer aluminium core PCBs involve plating after drilling to establish reliable interconnections between layers. This ensures stable performance in more complex electronic applications.
Multi-Layer Aluminum PCB:
For advanced aluminum PCB boards, the process requires inner layer processing, initial lamination, secondary lamination, drilling, plating, and outer layer circuit formation. Final steps include solder mask application, silk screening, surface treatment, punching and board separation, testing, inspection, and packaging.

What are the advantages of using Aluminum PCBs over traditional FR4 PCBs?
If your design involves high-power, high-heat applications (like LED lighting, power converters, automotive electronics, or telecom systems), Aluminum PCBs are the better choice over FR4. They ensure longer lifespan, better thermal stability, and reduced total system cost. To know about the details, click for Aluminium PCB vs FR4 PCB
What aluminum core thickness actually does?
Thermal path: Thicker aluminum spreads heat laterally but the dielectric layer (not the aluminum) dominates junction-to-base thermal resistance.
Stiffness/flatness: Bending stiffness scales ~ with thickness³. Thicker cores stay flatter over large panels or heavy parts.
Weight & cost: More metal = heavier (shipping/mounting) and slightly higher processing cost.
Assembly: Very thick cores (≥3.0 mm) need larger panel tabs/stronger depaneling; small PCBs may be harder to break out.
What's the Typical choices (rule-of-thumb) of thickness of aluminium core PCB?
0.8–1.0 mm: Tight spaces, handheld/portable, light components, moderate heat.
1.5–1.6 mm (most common): LED modules, general power boards—good stiffness + manageable weight.
2.0 mm: Higher power density, larger boards, automotive/industrial vibration.
3.0 mm+: Heavy heat loads or large panels needing rigidity; check machining/depaneling limits.
How to choose according to the application?
LED lighting (COB/COG modules): 1.0–1.6 mm Al, dielectric 75–100 µm @ 1–3 W/m·K. Click for PCB for LED lights
Power supplies / motor drivers: 1.6–2.0 mm Al, thicker Cu (2 oz) if needed. Click for Power Supply PCB Board
Automotive/industrial, high vibration: 2.0 mm (or 3.0 mm for large/heavy assemblies). Click for Automotive PCB
What surface finishes are compatible with Aluminum PCBs?
Popular surface finishes for aluminum PCBs include OSP, ENIG, and HASL. However, due to the unique properties of aluminum, some surface finishes may not be suitable, and it is important to consult with the aluminum base PCB supplier for guidance.
