Backplane PCB

Product Description

A backplane (or "backplane system") is a circuit board (usually a printed circuit board) that connects several connectors in parallel to each other, so that each pin of each connector is linked to the same relative pin of all the other connectors[1], forming a computer bus. It is used as a backbone to connect several printed circuit boards together to make up a complete computer system. Early personal computers like the Apple II and the IBM PC integrated an internal backplane for expansion cards. [citation needed]. While a motherboard may include a backplane, [citation needed] the backplane is actually a separate entity. A backplane is generally differentiated from a motherboard by the lack of on-board processing power where the CPU is on a plug-in card. [citation needed]

Backplanes are normally used in preference to cables because of their greater reliability. In a cabled system, the cables need to be flexed every time that a card is added to or removed from the system; And this flexing eventually causes mechanical failures. A backplane does not suffer from this problem, so its service life is limited only by the longevity of its connectors. For example, the DIN 41612 connectors used in the VMEbus system can withstand 50 to 500 insertions and removals (called mating cycles), depending on their quality.

In addition, there are bus expansion cables which will extend a computer bus to an external backplane, usually located in an enclosure, to provide more or different slots than the host computer provides. These cable sets have a transmitter board located in the computer, an expansion board in the remote backplane, and a cable between the two.
