In the cost comparison, copper PCB is more expensive than FR4 and has superior performance. The thermally conductive dielectric material of the copper PCB is a thermal bridge connecting the components and the metal plate. It can automatically transfer heat to the radiator through the magnetic core. Copper back PCB is assembled with copper back, high thermal conductivity dielectric layer and standard circuit layer. The circuit layer is a thin PCB bonded with a copper backplane. For FR4 PCB, it uses normal processing methods: drilling, milling, v-notch, and counterbore. Therefore, it requires an additional heat sink to conduct the heat in the circuit layer. Otherwise it will potentially destroy the hot spot. For car headlights, we generally choose copper pcb because copper has good thermal conductivity, no foaming and stratification at a high temperature of 280鈩? high pressure resistance, no additional radiator, greatly reduced volume, and improved mechanical processing performance.
