MetalcorePCB advantages
MetalcorePCB manufacturer learned that,Metal Core PCBs or MCPCBs are the types of PCBs that contain a base metal material as opposed to the traditional FR4. The core is usually designed to redirect heat away from the components. The metal core is composed of a metal plate of a particular thickness which dissipates heat.
Metal core PCB materials and thickness
PCBmanufacturer learned that,the metal core of the thermal PCB can be aluminum (aluminum core PCB), copper (copper core PCB or a heavy copper PCB) or a mixture of special alloys. The most common is an aluminum core PCB.
The thickness of metal cores in PCB base plates is typically 30 mil - 125 mil, but thicker and thinner plates are possible. MCPCB copper foil thickness can be 1 - 10 oz.
On one hand, metal core PCB is mainly in improving the reliability of devices that run at slightly higher temperatures. Not only does it allow for components to be mounted, but also draws heat from hot-running components to the other side of the board where it is dissipated, which will improve performance and life. As well as metal core PCB has great effect on solving the problem of overheating caused by large number of LEDs in devices.
FPCsupplier learned that,on the other hand, metal core PCB can make full use of its ability to integrate a dielectric polymer layer with a high thermal conductivity for a lower thermal resistance.
