Abstract: A connector for microelectronic elements includes a sheet-like body (30) having a plurality of holes (36), desirably arranged in a regular grid pattern. Each hole is provided with a resilient laminar contact (38) having a plurality of projections (42) extending inwardly over the hole in the body. Microelectronic elements (68) having bump leads (70) such as solder balls thereon may be engaged with the connector by advancing the bump leads into the holes of the connector to engage the bump leads with the contacts. The assembly can be tested, and if found acceptable, the bump leads can be permanently bonded to the contacts.

Abstract: A connector (10) for microelectronic elements includes a sheetlike body (24) having a plurality of active contacts (22) arranged in a regular grid pattern. The active contacts (22) may include several metallic projections (28) extending inwardly around a hole (27) in the sheetlike element (24), on a first major surface (32). A support structure such as a grid array of noncollapsing structural posts (23) is on a second major surface (33), and each of the posts (23) is electrically connected to one of the active contacts (22). The grid array of the posts (23) and the grid array of active contacts (22) are offset from one another so that an active contact (22) is surrounded by several posts (23). The posts (23) support the sheetlike element (24) spaced away from a substrate (41) to which the posts (23) are attached. A microelectronic element (45) having bump leads (46) thereon may be engaged by contacting the bump leads (46) with the active contacts (22), and deflecting the sheetlike element (24) between the bump leads (46) on one side and the posts (23) on the other side.

Abstract: An interposer for interconnection between microelectronic circuit panels (260) has contacts (250) at its surfaces. Each contact has a central axis normal to the surface and a peripheral portion adapted to expand radially outwardly from the central axis responsive to a force applied by a pad (262) on the engaged circuit panel. Thus, when the circuit panels (260) are compressed with the interposers, the contacts expand radially and wipe across the pads (262). The wiping action facilitates bonding of the contacts to the pads, as by conductive bonding material (246) carried on the contacts themselves.

Abstract: A microelectronic connection component (62) has flexible leads (36) formed by polymeric strips (46, 50) with metallic conductors thereon. The metallic conductors (46, 50) may be very thin, desirably less than 5 microns thick, and provide good fatigue resistance. Each strip (46 or 50) may have two conductors thereon, one serving as a principal or signal conductor for connection to a contact on a chip (62) or other microelectronic element and the other serving as potential reference or ground conductor. The potential reference conductor on the lead provides enhanced resistance to crosstalk.
