Abstract:
1. A package structure, comprising: a substrate comprising a first solder pad and a second solder pad thereon; a conductive element on the substrate, wherein the conductive element has a body comprising an outer surface including a top surface, a bottom surface, a first lateral surface and a second lateral surface, wherein the conductive element comprises a first electrode and a second electrode, wherein the first electrode is disposed on a first portion of the outer surface and configured from a first portion of the bottom surface, via a portion of the first lateral surface, to a first portion of the top surface, and the second electrode is disposed on a second portion of the outer surface and configured from a second portion of the bottom surface, via a portion of the second lateral surface, to a second portion of the top surface; a first metallic material overlaying on the first electrode and the second electrode, wherein the first metallic material is in contact with the first solder pad and the second solder pad to electrically connect the first solder pad and the second solder pad to the first electrode and the second electrode, respectively; a second metallic material overlaying on the first metallic material, wherein a first and a second portion of the second metallic material extend respectively from a third and a fourth portion of the bottom surface of the body of the conductive element to the substrate, wherein the third and the fourth portion of the bottom surface are between the first and the second portion of the bottom surface of the body of the conductive element; and the first metallic material has a lower melting point than the second metallic material.
