ABSTRACT:
Assemblies and methods for interconnecting integrated circuits, particularly prepackaged ones, are disclosed. A multi-level electrical assembly--composed of a pin carrier, a set of pads, such as for receiving a surface-mounted integrated circuit, and a set of conductive pathways coupling the pads and the pins--can connect one or more integrated circuits to the socket or other attachment area of a circuit board. The pathways pass through a multi-layered interconnect board, which can be configured to permit any translation of pads to pins for different purposes, or to permit the coupling of additional circuit elements, such as a coprocessor or passive circuits, to the pathways. Inventive methods for forming the assemblies, and inventive systems in which the embodiment of the assembly can be used to increase circuit board density, are also disclosed.
