Definition Of Aluminum Substrate

Aluminum substrate is a metal-based copper clad laminate with good heat dissipation function. Generally, a single-sided panel consists of three-layer structure, which are circuit layer (copper foil), insulating layer and metal base layer. For high-end use, there are also double-sided designs with a structure of circuit layer, insulating layer, aluminum base, insulating layer, and circuit layer. Very few applications are multi-layer boards, which can be made by laminating ordinary multi-layer boards with insulating layers and aluminum bases.

LED aluminum substrate is PCB, which is also the meaning of printed circuit board, but 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 generates a lot of heat, the circuit board for LED lamps is generally Aluminum substrate, which can conduct heat quickly, and other circuit boards for equipment or electrical appliances are still glass fiber boards
