Designing High Current PCBs

requires a careful balance of electrical performance and thermal management. To minimize resistance and heat generation, these boards utilize wider traces and thicker copper layers (typically 2oz or more), strictly adhering to standards like IPC-2152. Thermal management is paramount; designers employ strategies like thermal via arrays to transfer heat to inner ground planes, copper pours for heat spreading, and high-Tg or metal-core substrates for superior dissipation. Additionally, layout optimization—such as keeping high-current paths short and isolated from sensitive signals—reduces electromagnetic interference (EMI) and prevents hotspots.
