Double Sided Copper Core PCB can have more space for components by having conductive layers on both sides, which can increase circuit density and complexity with ease. By the way, of all the metal core PCB options, copper has the highest level of thermal conductivity, Copper clad PCB have 2X thermal conductivity compared to aluminum PCBs. With higher conductivity, the heat transfer and dissipation are much stronger. In environments where high temperatures are involved, standard PCBs, such as FR-4 boards, may not withstand the heat, causing extensive damage. A Copper based PCB will redirect heat from critical circuits, preventing performance issues and extending its life span.
