Patent ID: 8476773

Claim:
An electrical structure comprising: a first substrate comprising a first electrically conductive pad; a second substrate comprising a second electrically conductive pad; and an interconnect structure electrically and mechanically connecting said first electrically conductive pad to said second electrically conductive pad, wherein said interconnect structure comprises a non-solder metallic core structure, a first solder structure in direct mechanical contact with a first portion of said non-solder metallic core structure, and a second solder structure in direct mechanical contact with a second portion of said non-solder metallic core structure, wherein said first solder structure electrically and mechanically connects said first portion of said non-solder metallic core structure to said first electrically conductive pad, and wherein said second solder structure electrically and mechanically connects said second portion of said non-solder metallic core structure to said second electrically conductive pad.
