While pure gold is shiny, it is impractical; the \"hard gold\" plating process is the true key to ensuring stable, reliable connections during repeated insertion and removal. The real value of the gold fingers found on industrial motherboards and graphics cards lies in the plating process itself, not merely in their visual luster. Understanding these details will help you select more durable hardware and avoid equipment failures caused by poor contact."}
