The term Backplane PCB generally refers to larger format boards connecting several PCBs together in order to form a computer bus.
Backplane PCBs are generally used as a backbone within a system such as control panels for industrial, computing, and military use. They provide greater reliability in connecting multiple PCBs due to their static nature, as opposed to cables that need to be flexed every time a card is removed, thereby reducing the life of that component / connection.
