Abstract
A method and system of producing metal cored solder structures on a substrate which includes: providing a decal having a plurality of apertures, the apertures being tapered from a top surface to a bottom surface; positioning a carrier beneath the bottom of the decal, the carrier having cavities located in alignment with the apertures of the decal; positioning the decal on the carrier having the decal bottom surface in contact with the carrier top surface to form feature cavities defined by the decal apertures and the carrier cavities; positioning a plurality of metal elements in the feature cavities; filling the feature cavities with molten solder and cooling the solder; separating the decal from the carrier to partially expose metal core solder contacts; positioning the metal core solder contacts on receiving elements of a substrate; and exposing the metal core solder contacts on the substrate.
