Heat Sink PCB is a special technology provides a path for heat from the Heat source to outside or inside medium. Heat Sink PCB normally can dissipate power in three ways: conduction (heat transfer from one solid to another metal core), convection (heat transfer from a solid to a moving fluid, for most power supply or LED applications the fluid will be air), Radiation (heat transfer from two bodies of different surface temperatures through Thermal radiation).

MCPCB or calls Metal Core PCB, IMS PCB, Aluminum PCB or calls Insulated Metal Substrate PCB means the base material for PCB is metal, but not normal FR4 material, The heat dissipation of metal core PCB is improved through affixing the common PCB to another copper or aluminum metal with better thermal conductivity.The metal substrate normally included aluminum, copper, iron and silicon steel plate, insulating media with high thermal conductivity.The main difference between a FR4 PCB and MCPCB is the thermal conductive dielectric material in the Metal Core PCB. This acts as a thermal bridge between the IC components or LED lighting and metal backing plate. Heat is conducted from the package through the metal core to another heat sink. In addition,The metal core PCB with both silicon,iron base and steel base are excellent in electrical properties, permeability, pressurization and high strength and are mainly used in brushless DC motor PCB, tape recorders PCB and intelligent driver PCB.
