Compared to traditional FR-4 PCBs,Aluminum clad PCB offer greater heat dissipation, thanks to 5 to 10 times higher thermal conductivity and up to 10 times less thickness with respect to conventional architectures. The particularly efficient transfer of thermal energy allows metal PCBs to use very light copper layers, reducing both costs and thickness of the solution. Aluminum Core PCB is composed of a dielectric layer capable of offering high thermal conductivity (and therefore high dissipation), a metal layer and a copper film with high heat dissipation capacity and mechanical strength. The metal layer can be composed entirely of metal, or a combination of fiberglass (FR-4) and metal. Since metal is able to easily transfer heat by subtracting it from high-power components, typical applications of metal PCBs include power supplies, power converters, LED lighting systems and power circuits in automotive environments (headlights, lights, cooling, climate and more). This type of technology, in addition to efficient thermal management, allows to extend the components lifetime, improving the reliability of the overall circuit.
