Abstract
Abstract A solder-bearing lead for attachment to the surface of a substrate, wherein a discrete mass of solder is mechanically held firmly by the lead in a position permitting close proximity to the substrate surface to connect the lead to the substrate with an electrical and mechanical bond upon melting of the solder, the lead body having a pair of fingers partially encircling the solder mass with a gap between the fingers providing an unobstructed flow for the melted solder to the substrate. The lead may also be used to interconnect a first substrate to a second substrate, forming a bond between conductive areas on both substrates.
