What Is Aluminum Substrate PCB Circuit Board

Aluminum Core PCB common in LED lighting products. There are two sides on the front and back sides. The white side is soldered to the LED pin, and the other side is in the form of aluminum. It is usually coated with a thermal conductive paste and then in contact with the heat conducting portion. There are also ceramic substrates and the like.


The aluminum substrate is a metal-based copper clad laminate with good heat dissipation function. Generally, single side aluminum substrate PCB is composed 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 sided aluminum core CCL(copper claded laminate), the structure is circuit layer, insulation layer, aluminum base, insulation layer, circuit layer. A very small number of applications are multi-layer PCB circuits boards, which can be made of ordinary multi-layer circuit boards combined with an insulating layer and an aluminum base.


The LED aluminum substrate PCB, which is also the meaning of the printed circuit board. The material of the circuit board is aluminum alloy. In the past, the material of our general circuit board was glass fiber, but because the LED heat is large, the circuit board for LED lamps, The aluminum substrate can conduct heat quickly, and the circuit board for other equipment or electrical appliances is still a fiberglass circuit board!
