At Xinrongxing PCB, we specialize in manufacturing LED PCBs, designed for optimal heat dissipation, reliability, and efficiency. LED PCB technology has evolved into the foundation of many innovative lighting products. In LED applications, chips are soldered directly onto the circuit board, producing light when electrically connected. To manage heat, heat sinks and ceramic bases are often used to attach the chips, cooling the LEDs during operation.
LED PCBs are crucial because LEDs generate substantial heat, and conventional cooling methods are often insufficient. This is why LED circuit boards are designed to enhance thermal management, with aluminum substrates being particularly popular. Aluminum PCBs typically include a thin layer of thermally conductive dielectric material, which efficiently relocates and dissipates heat, offering superior performance compared to standard rigid PCBs.
