Printed circuit boards, or PCBs, are physical boards designed to interconnect various electronic components through the use of conductive copper strips attached to a non-conductive substrate. PCBs are a basic building block of any electronic component. By themselves, they may not hold much function, but when components are attached and they are connected with other PCBs, they have the possibility of becoming single board computers, system host boards, or any other electronic system you can conceive. Backplane connectors are the key to PCBs becoming a more complex system. Backplane connectors, or sometimes just referred to as “backplanes”, are a type of connector that enables coupling of PCBs with each other.
