Product Description
2mm Thickness 2OZ ENIG Aluminum PCB for Power Applications
Aluminum substrate is a functional circuit board with aluminum (or aluminum alloy) as the base material. It is primarily composed of a circuit layer (copper foil), insulation layer, and metal base layer. Its core value lies in efficient heat dissipation and high power carrying capacity, making it widely used in electronic devices that are sensitive to heat or require high current drive.
Key Features of Aluminum PCB
- Excellent heat dissipation performance: Aluminum substrate thermal conductivity (150~240 W/(m*K)) significantly outperforms standard FR-4 epoxy resin boards (0.3~0.5 W/(m*K)), enabling rapid heat transfer to housing or heat sinks to prevent local overheating
- Superior electrical performance: Insulation layer dielectric constant (3~5) is optimized for medium and high frequency circuits, though ceramic substrates remain preferred for high-frequency applications
- High rigidity and structural stability: Aluminum substrate mechanical strength exceeds organic substrates like FR-4, providing excellent resistance to bending and vibration for demanding automotive and industrial applications
Primary Applications
- LED lighting systems: Effectively manages high heat generation from LED lamp beads in street lights, spotlights, and automotive headlights to ensure stable performance and extended lifespan
- Power supply and power devices: Ideal for high-current applications including switching power supplies, inverters, and frequency converters, efficiently dissipating heat from IGBTs and MOS transistors
- Automotive electronics: Essential for on-board chargers (OBCs), DC-DC converters, and automotive lighting drive modules operating in high-temperature engine compartment environments
- Industrial control systems: Provides reliable heat dissipation and circuit integration for high-voltage equipment including servo drives and PLC controllers
