General description
Metal core PCBs are thermal management circuit boards which use a base metal material as the heat dissipater part of the PCB. The metal core can be aluminum (aluminum core PCB),copper (copper core PCB) and iron (iron core 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. |
