Large-Area, Flat Construction
Each Large Size Aluminum Base LED PCB is produced on a 6061/5052 aluminum base with anodized surface treatment, available in large panel formats up to 600×600 mm and beyond. A dedicated large-area manufacturing process controls warp and bow, ensuring excellent flatness for consistent LED placement, uniform light output, and reliable SMT assembly across the entire panel.
Efficient Thermal Management
The aluminum base offers a thermal conductivity of approximately 150 W/m·K, paired with a thermally conductive dielectric layer (1–9 W/m·K, 50–150μm). This creates a short vertical heat path that rapidly conducts heat away from LED junctions, lowering junction temperature, reducing light output degradation, and significantly extending LED lifetime — essential for high-power LED lighting panels.
High-Current Capability
Thick copper (1–4 oz) with wide power traces handles the drive current required by high-power LED modules, minimizing I²R self-heating and voltage drop across the large panel. The result is stable brightness, even current distribution, and reliable operation at full power.
Reliable Electrical Performance
The single-layer circuit with the aluminum base as a reference plane provides low DC resistance and excellent current uniformity, ideal for LED constant-current driving and PWM dimming. High insulation resistance and dielectric withstand (AC 1500–2500V) ensure electrical safety. The anodized aluminum base offers corrosion resistance for humid and outdoor environments.
