A Copper Coin PCB is a multi-layer printed circuit board that has a solid copper “coin” or block embedded into its structure to provide advanced thermal management . These coins create a direct, low-resistance thermal path from heat-generating components to an external heat sink, significantly improving heat dissipation compared to traditional methods like thermal vias.
