Metal core PCBs also called MCPCBs, whose substrate layer is a metal base. The most common metals of MCPCBs used are aluminum, copper, and steel alloy. Aluminum-based PCBs are the most cost-effective; they exist good heat conductivity and thermal dissipation ability at low prices. Copper-based PCBs perform better than aluminum, but the price is higher. Steel-based PCBs are harder than... https://www.hycxpcba.com/ability/pcb-prototype.html
