Expansion cards add specific functionality to rackmount industrial servers through expansion slots, such as additional connectivity, processing power, or specialized interfaces for industrial applications.
Industrial expansion cards typically use FR-4 PCB material with copper traces and include electronic components like ICs, capacitors, and resistors for reliable performance in demanding environments.
Key components include an edge connector for slot interface, primary controller chip for functionality management, and a printed circuit board (PCB) that houses all electronic components.
