The LED circuit board is a kind of printed circuit board, which is to print the circuit on the aluminum plane with good thermal conductivity, and then solder the electronic components on it.
LED aluminum substrate is PCB, which is also the meaning of printed circuit board. The material of the circuit board is aluminum alloy. In the past, the material of our general-purpose circuit boards was glass fiber, but due to the large heat of LEDs, the circuit boards of LED lights are generally aluminum substrates that can quickly conduct heat, and the circuit boards of other equipment or electrical appliances are still glass fiber boards!
Compared with the traditional FR-4, the aluminum substrate can reduce the thermal resistance to a very low level (heat resistance is comprehensive) to reflect the parameters of the ability to block heat transfer. In heat transfer engineering applications, in order to meet the requirements of the production process, sometimes by reducing thermal resistance to enhance heat transfer; sometimes increasing thermal resistance to inhibit heat transfer), aluminum substrates have excellent thermal conductivity; compared with thick film ceramic circuits, Its mechanical properties are very excellent.
