What is an aluminum PCB board?

A Aluminum PCB Board Is a metal -based circuit substrate that displays a thin dielectric layer between the alloy alloy base and the copper circuit layer, offering superior thermal conductivity compared to traditional FR4 materials. Engineering for high power applications such as LED lighting, power modules, and automotive systems, efficiently transferring heat from components, ensuring reliability in an environment that demands while maintaining electrical insulation and mechanical resistance.

How to optimize the aluminum PCB design for a brighter LED ship lamp?

• Increase the thickness of copper: Use 2-3 oz copper (not 1 ounce) to reduce resistance, allowing current output and brighter higher.
• Optimize the width & distance of tracks: A broader footprint minimizes the decrease in voltage, while the right distance prevents excessive heat and ensures the distribution of uniform light.
• Choose high -performing LEDs: Choose high lumen (eg Cob or SMD 5050) with high CRI (color rendering index) for real and real lighting.
• Increase thermal conductivity: Use a high-conductivity-conductivity-conductivity layer (for example, 2.0 W/Mâ · K or higher) to eliminate heat efficiently, maintain the brightness of the LED.
• Reflective surface maintenance: Apply a white solder mask or reflective coating to maximize light output by minimizing absorption.
• Proper LED layout: Adjust the LED evenly with an optimal distance to avoid dark spots and ensure uniform brightness throughout the lights.
