Single Layer MCPCB Design for Effective Heat Dissipation Solution
Cut Costs with Copper (Without Overspending)
- Use a 1.6mm copper-core MCPCB for LEDs >5W—it’s 30% pricier than aluminum but extends LED lifespan by 50%. For low-power LEDs, 1.0mm aluminum saves 20% upfront while handling 90% of use cases.
Arrange LEDs Like a Parking Lot (Not a Traffic Jam)
- Space LEDs 20mm apart in a grid to avoid heat pileup. One client reduced field failures by 40% by redesigning a crowded board into zones with dedicated thermal vias.
Drill Tiny Holes, Solve Big Problems
- Add 3–5 thermal vias (0.4mm) under each LED. This simple step lowers thermal resistance by 25%, preventing performance drops in high-summer outdoor fixtures.
Skip the Glue—Solder Directly to Save Time and Money
- Solder LEDs to ENIG-finished copper pads instead of using thermal paste. A manufacturer saved $0.15 per board and reduced assembly time by 12 seconds per unit.
Stand It Up to Cool It Down
- Install the MCPCB vertically in fixtures. Natural airflow cuts operating temps by 8–12°C compared to flat mounting—no fans needed.
Special Instructions for High Power Single Layer MCPCB Design
Material Selection: Balance Performance and Budget
- Use 2–3mm copper-core MCPCB for LEDs exceeding 10W—copper’s 380 W/m·K conductivity ensures rapid heat spreading.
- For LEDs ≤5W, opt for 1.5mm aluminum-core boards to cut material costs by 30% while maintaining acceptable thermal performance.
LED Layout: Grid Spacing and Thermal Zoning
- Arrange high-power LEDs in a 20–25mm grid to prevent heat overlap. Group LEDs into 4–6 thermal zones, each linked to dedicated thermal via clusters.
- Example: A 100W LED array (10 x 10 LEDs) benefits from 4 zones with 25 LEDs each, reducing edge-to-center temperature gradients by 15–20%.
Thermal Vias: Quantity Over Size
- Drill 0.3–0.5mm diameter vias directly under LED pads. Aim for 5–8 vias per high-power LED (e.g., 500+ vias for a 100-LED board) to minimize thermal resistance.
- Stagger vias in a hexagonal pattern to improve heat flow efficiency by 25% compared to linear arrays.
Surface Finish: Direct Soldering for Lower Resistance
- Specify ENIG (Immersion Gold) pads for LED mounting—eliminates thermal interface materials (TIMs) and reduces contact resistance by 40% vs. HASL finishes.
- Ensure pad diameters are 10–20% larger than LED bases to accommodate thermal expansion without solder voids.
Forced Airflow Integration (If Enclosed)
- Add 30x30mm fans at board corners for enclosed fixtures. A 2.5 m/s airflow lowers junction temperatures by 10–18°C, enabling 15–20% higher drive currents.
- For outdoor use, replace fans with 20mm black-anodized aluminum heat sinks on board edges—radiates heat 20% faster in sunlight.

Advanced Dielectric Materials with Ceramic Fillers
- Use ceramic-filled polymer composites (e.g., alumina or boron nitride) for the dielectric layer. These materials achieve 1–3 W/m·K thermal conductivity while maintaining electrical isolation (>5 kV/mm), balancing safety and heat transfer. Example: A 75µm ceramic-filled layer reduces thermal resistance by 30% vs. standard epoxies.
Laser-Drilled Microvias for Precision Thermal Paths
- Adopt laser drilling to create 0.1–0.3mm microvias beneath LED pads. This enables 20–40% higher via density vs. mechanical drilling, crucial for high-power LEDs (e.g., 50+ vias per 10W LED). Laser drilling also minimizes via distortion, ensuring consistent thermal performance.
Chemical Etching for Optimized Trace Routing
- Use chemical etching to create 0.2–0.5mm traces with smooth edges. This reduces resistive losses by 15–20% compared to mechanical milling, preserving power efficiency. For 100A+ currents, widen traces to 2–3mm near LED pads to avoid hotspots.
Embedded Heat Pipes for Edge-to-Edge Cooling
- Integrate 3–5mm diameter flat heat pipes into the MCPCB’s edges. These pipes transport heat 5–8x faster than solid copper, ideal for large boards (e.g., 400x400mm). Pair with forced airflow to lower edge-to-center temperature differentials by 25–35%.
Machine Learning-Driven Thermal Simulation
- Leverage AI-powered tools like 6SigmaET to predict heat flow in complex layouts. These tools analyze 10,000+ data points per board, identifying weak spots 40% faster than traditional CFD software. One client reduced prototyping cycles by 50% using this approach.
