Abstract
A microelectronic connection component has flexible leads formed by polymeric strips with metallic conductors thereon. The metallic conductors may be very thin, desirably less than 5 microns thick, and provide good fatigue resistance. Each strip may have two conductors thereon, one serving as a principal or first signal conductor for connection to a first contact on a chip or other microelectronic element and the other serving as potential reference or ground conductor, or as a second signal conductor connected to a second contact on the chip. The system provides enhanced resistance to crosstalk and rapid signal transmission, and is compatible with differential signal transmission.
