What is Multi Layers Metal Core Pcb?

In a multilayer metal core printed circuit board (MCPCB), the layers will be evenly distributed on each side of the metal core. For instance, in a 12-layer board, the metal core will be at the center with 6 layers on the top and 6 layers at the bottom.

Metal core PCBs are classified into different types based on the number of trace layers and the location of the metal core. Two (Double) layers metal core Printed Circuit Boards have two layers of copper conductor on one side of the metal core. A two layer metal core Printed Circuit Board requires an extra step to laminate the metal core and imaged thermal conductive laminate.

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 the first two materials, while with a lower heat conductivity. Metal PCBs are known as their excellent thermal dissipation.The benefits of the metal core PCBs

Excellent thermal dissipation

Thermal conductivity refers to the thermal performance parameters of a material. The thermal conductivity of Metal core PCBs like aluminum PCBs exhibits higher than other PCBs that use FR4 and CEM3 as the substrates. High thermal conductivity makes metal core PCBs have an excellent heat dissipation ability. The heat produced by ICs and components will be removed quickly, which helps to reduce the heat damage of the components and prolong the service life of the products, as well as improve the performance.

Good heat dissipation of metal core PCBs makes them less prone to high temperature, which causes less distortion during signal transportation.

The advantages mentioned above make metal core PCBs ideal solutions in many applications, such as power converters, lightings, photovoltaic, backlight applications, automotive LED applications, home appliances, and so on. Aluminum-based PCB is the most common type of metal core PCBs for its cost advantage. Especially in solid-state lighting, aluminum PCBs helps achieve higher lighting levels with less quantity of LED.

The copper foil thickness of MCPCB can be 1oz to 10oz, and the metal core thickness of the boards usually is 30mil to 125mil.
