LED lighting aluminum PCBs are composed of a thin layer of dielectric material that provides excellent thermal conductivity and electrical insulation, sandwiched between the copper circuit layer and the aluminum PCB, which effectively dissipates heat and ensures separation of electronic components. This unique structure achieves optimal thermal management crucial for high-power LED applications, with additional advantages including improved thermal conductivity, increased durability and stability, lightweight construction, and cost-effectiveness. Different types of aluminum PCBs, such as flexible aluminum, mixed aluminum, and multi-layer aluminum, offer varying benefits and are widely used in fields such as communication, power, electronics, medical equipment, mechanical equipment, and lighting.
