An electronic system is a hierarchical interconnection network that enables communication among different electronic devices. Several interconnects are required for the signal transmission and power distribution needed to ensure proper functioning of electronic devices. 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.
Six levels of interconnection are normally seen in electrical connectors. 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. Level 1 is the connection between a component lead and a printed circuit board (PCB), exemplified by chip carrier sockets, dual inline
