Thick 0.2mm 6mm SMD LED Circuit Board Full Power Floodling Light Source

YIZHUO has been participated in all kinds of LED lighting projects, by supplying LED PCB( LED circuit board) with using CEM3, FR4, aluminum, and copper alloy as the LED PCB base material. There is no doubt that, compare to CEM 3and FR 4 material, aluminum and copper alloy have better performance on heat transfer, however, since copper alloy price is much higher than aluminum, so we can say. in the LED lighting industry, aluminum is absolutely the most economic option considering thermal conductivity. rigidness, and cost.
