Maximizing Efficiency: How FX Metal Core PCBs Boost Performance Metal Core PCBs, or Metal Core Circuit Boards, are specially designed with a metal core layer at the centre. Unlike traditional FR-4 PCBs that use a fiberglass core, Metal Core PCBs feature a thermally conductive metal core, typically aluminium, copper, or steel. This metal core provides superior heat dissipation capabilities, making Metal Core PCBs ideal for applications that require efficient thermal management. https://sfxpcb.com/maximizing-efficiency-how-fx-metal-core-pcbs-boost-performance/
