General Profile
Metal core PCB is thermal management circuit board used in LED lighting which
needs fast cooling dissipation. The metal core can be aluminum (aluminum core
PCB) and copper (copper core PCB), even iron base. The fastest speed of heat
transfer is on copper which is designed in the form of thermoelectric separation.
Advantages
1) Effective heat dissipation reduces the operating temperature of the module
and prolongs the service life;
2) Power density and reliability are improved up 10%;
3) Reduce the dependence of heat sinks and other hardware (including thermal
interface materials);
4) Reduce the volume of the product;
5) Reduce the cost of hardware and assembly;
6) Optimization combination of power circuit and control circuit;
7) Replace the fragile ceramic substrate and obtain a better mechanical durability;
8) Reduce the operating temperature of the equipment;
Applications
LED lighting, Switch regulator, DC/AC converter, Communication electronic
equipment, A filter electric circuit, Office automation equipment, Motor driver,
Motor controller, Automobile etc.
