interposer

1. (electronics) An electrical interface between one connection or socket and another, used to spread a connection to a wider pitch or to reroute it.Examples: "The drillable centre-line determining device disclosed in this patent takes the form of an interposer which has on its underside a projecting location pin perpendicular to its upper surface which acts as a planarisation platform."; "As the name suggests, an interposer is placed in between the packaging substrate and dies to provide electrical interface routing. The objective of an interposer is to electrically reroute a terminal to different dies or to extend a connection to broader areas via wider pitch."
