What is Aluminum PCB For LED?
Aluminum PCB for LED is a metal-based printed circuit board specifically designed for LED lighting. It achieves efficient heat dissipation by combining an aluminum substrate with insulating layers, ensuring the stable operation of high-power LED fixtures and extending their lifespan.
What Are the Advantages of Aluminum PCB For LED?
Here are main advantages of aluminum PCB for LED:
- Efficient heat dissipation: quickly export the heat generated by the LED, reduce the operating temperature and extend the service life.
- High current carrying capacity: carry higher current than traditional PCB at the same thickness, suitable for high-power scenarios.
- Lightweight: lightweight aluminum material, simplifying installation and reducing the overall weight of the equipment.
- Process compatibility: adapt to SMT mounting technology to simplify mass production process
- High mechanical strength: impact and vibration resistance, adaptable to harsh working environments.
- Electromagnetic shielding: effectively reduce electromagnetic interference and improve circuit stability.
- High voltage resistance: support voltage above 3000V to ensure safe operation.
- Environmentally friendly and recyclable: aluminum material is non-toxic and recyclable, meeting environmental standards.

What Are the Materials of Aluminum PCB Board For LED?
Here are the materials of aluminum PCB board for LED:
- Substrate Layer–Aluminum(such as 6061 Aluminum alloy)
- Insulation layer–FR4 for normal thermal conductivity; ceramic powder mixture (such as alumina), silicone or special polymer for high thermal conductivity
- Conductive layer–Copper foil (1oz~6oz thickness), used for circuit routing.
- Surface treatment layer– OSP, HASL, silver/gold plating
- Additional coating–White solder mask ink (high reflection), black solder mask (anti-light interference)

How to Design Aluminum PCB Board For LED?
Aluminum PCB for LED Design is mainly divided into five steps:
1. Basic design
- Select single/double-sided board: single-sided board (aluminum base + insulation layer + copper foil) for simple circuits, double-sided board for complex wiring.
- Aluminum base thickness: conventional 1.0~1.5mm, high power 2.0~3.0mm (such as 5052/6061 aluminum).
2. Circuit layout
- LED arrangement: evenly distributed, spacing ≥3mm (to prevent heat concentration).
- Line width calculation: Formula: Line width (mm) = current (A) / (copper thickness × 0.038).
- Wiring rules: Low voltage line spacing ≥ 0.2mm, high voltage (>50V) ≥ 1.0mm; Sharp angle routing is prohibited (arcs or 45° fold lines are preferred).
3. Pad design
- Size: 0.2~0.5mm larger than the LED pin (compatible with soldering process).
- Surface treatment: OSP is selected for general use, and immersion gold/silver plating is used for high reliability.
4. Thermal management
- Thermal conduction path: The aluminum base directly contacts the heat sink (insulating gasket is prohibited).
- Thermal resistance target: Total thermal resistance <5℃/W (high power requires <3℃/W).
- Verification method: Infrared thermal imager measures temperature rise (full load T<30℃).
5. Design output
- Gerber file: Insulation layer thickness, copper foil parameters, and Mark points are marked.
- DFM check: Line width error <±10%, pad and aluminum base edge >1mm.
