LED Aluminum PCB is composed of the circuit layer (copper foil layer), thermal insulation layer and the metal core layer. Circuit layer require great current-carrying capacity, thus should use thicker copper foil and generally the thickness is from 35um to 280um; Thermal insulation layer is the core technology of aluminum PCB, it is usually made up of special ceramics and fill special polymers, with small thermal resistance, good viscoelasticity, and has thermal aging ability, and can be able to withstand mechanical and thermal stress. Thermal insulation layer of IMS-H01、IMS-H02 and LED-0601 and other high-performance aluminum PCB are using this technology, which has the extremely good thermal conductivity and high strength electrical insulation;
Regarding Aluminum PCB or wrote as Aluminium PCB, there are different types of Aluminum which used for the laminate of Aluminium base pcb, the brief introduction as below,
