Abstract

The invention discloses a package structure with an overlaying metallic material overlaying a solder material. A substrate comprises a first solder pad and a second solder pad thereon. A conductive element on the substrate comprises a first electrode and a second electrode thereon. A solder material electrically connects the first solder pad and the second solder pad to the first electrode and the second electrode respectively. An overlaying metallic material overlays the exposed areas of the solder metallic material, the first solder pad, the second solder pad, the first electrode and the second electrode, wherein the exposed areas comprise metallic material having a lower melting point than the second metallic material.
