We offer a variety of LED PCB products. High-power LEDs for aluminum-based PCBs, copper-based PCBs, ceramic-based PCBs, low-power LEDs for FR4 PCBs, high-temperature PCBs. Due to the good heat dissipation performance of aluminum-based PCBs, the most commonly used high-power LED products are aluminum-based PCBs.
We can provide different solder mask options for your LED PCB. We have developed a lot of Led PCB solder mask lumens to provide better brightness for your Led lamps.
Led pcb board assembly is a metal-based copper clad laminate with good heat dissipation. Generally, a single panel consists of a three-layer structure, which is a circuit layer (copper foil), an insulating layer and a metal base layer. Also used for high-end use is designed as a double panel, the structure is circuit layer, insulation layer, aluminum base, insulation layer, circuit layer. A very small number of applications are multi-layer boards, which can be made of ordinary multi-layer boards combined with an insulating layer and an aluminum base.
