Technical Specifications: Circuits with Aluminum Core – MICRO-CIRCUITS

In Micro-Circuits, we take thermal dissipation technology to its highest expression. Our aluminum boards (Metal Core PCB) are the ultimate solution for high-power applications where heat management is the determining factor for product success.

1. Advanced Architecture and Thermal Management

Unlike traditional boards, our MCPCBs use a metallic substrate that acts as an integrated heat sink:

• Superior Thermal Conductivity: The ultra-thin yet high-density dielectric layer allows for efficient heat transfer from the components to the aluminum base, keeping semiconductor joints at optimal temperatures.

• Reduction of Hot Spots: Aluminum evenly distributes heat across the entire surface of the board, preventing catastrophic failures due to localized thermal stress.

2. Extended Lifespan and High Reliability

Durability is the cornerstone of our manufacturing inMicro-Circuits:

• Extended Life Cycle: By operating at lower temperatures, the lifespan of LEDs and power components increases by up to30% - 50%compared to conventional FR4 substrates.

• Dimensional Stability: The aluminum core provides exceptional structural rigidity, eliminating warping issues or cracks in the solder joints caused by differential thermal expansion.

• Oxidation Resistance: High-quality surface treatments that protect aluminum from corrosion, ensuring consistent performance in industrial environments.

3. Technical Manufacturing Specifications

• Base Material: High-purity aluminum alloys (Series 1000/5000).

• Copper Thickness: Available in 1 oz and 2 oz to support high current densities.

• Dielectric Strength: High voltage insulation (up to 3000V AC or higher as required) to ensure user and equipment safety.

• Surface Finish: Options in Bright White (highly reflective for LED) or Matte Black, with HASL or OSP finishes for superior solderability.

4. Critical Application Areas

• High Power LED Lighting: Street lighting, industrial floodlights, and automotive systems.

• Power Electronics: DC-DC converters, voltage regulators, and high-fidelity audio amplifiers.

• Switched Power Supplies: Where efficiency and miniaturization demand robust passive dissipation.
