The backplane system is used for connecting multiple plug-in cards along a single backbone to make a complete backplane system. A backplane system is widely used in computer and telecommunication systems because of its flexibility and reliability. EIA 700AAAB is a standard for mezzanine connectors.Ī backplane is a group of electrical connectors in parallel with each other so that each pin of each connector is linked to the same relative pin of all the other connectors, forming a connector bus. The operating temperature and humidity also should be considered.
Separability is dependent on many factors, such as whether the connector is separable or permanent, the number of mating cycles required over its lifetime, and the maximum and minimum value of insertion force required. The specifications that need to be considered when choosing a mezzanine connector include separability, mechanical requirements such as stack height and tolerances, constraints such as standoffs, brackets, or chassis slots and frames, and types of mountings.

Level 5 is the connection between physically separated systems typified by the link between a computer and a printer or other piece of peripheral equipment, or components of a local network.Ĭustom board-to-board connectors from Ironwood Electronics (left), parallel board-to-board connectors from Mill-Max (center), and Hirose’s FX27 Series FunctionMAX floating, card-edge board-to-board connector (right). Level 4 is the connection from a major subassembly to the input/output (I/O) port of the complete system. Level 3 is the connection between two subassemblies, such as a power supply and an associated subassembly. A motherboard–daughterboard connection is typical. Level 2 is the connection between two or more PCBs. Level 1 is the connection between a component lead and a printed circuit board (PCB), exemplified by chip carrier sockets, dual inline package (DIP) sockets, and switches.
Level 0 is the connection between a basic circuit element and its lead, such as the link between a semiconductor chip and the lead frame. Six levels of interconnection are normally seen in electrical connectors. Electrical connectors are classified into three types based on their termination ends: board-to-board connectors, cable/wire-to-cable/wire connectors, and cable/wire-to-board connectors. Several interconnects are required for the signal transmission and power distribution needed to ensure proper functioning of electronic devices.
