Little knowledge - Metal Core PCB
Metal core PCB's are thermal management circuit boards which use a base metal material as the heat dissipater part of the PCB. They are used in high heat generating application like LED lighting in the area of high power LED lighting, Automotive Interior, Exterior Lighting, Parking Garage Lighting, LED spot light etc.
The metal core can be aluminum (aluminum core PCB) and copper (copper core PCB). The most common used aluminum core PCB is the thermal conductivity at 1W/MK and 2W/MK.
