Abstract: An electronic device includes a substrate including first and second metal regions, a first passive device that includes a metal joining surface and is arranged on the substrate with the metal joining surface of the first passive device facing first metal region, a semiconductor die that includes a metal joining surface and is arranged on the substrate with the metal joining surface of the semiconductor die facing the second metal region, a first soldered joint between the metal joining surface of the first passive device and the first metal region; and a second soldered joint between the metal joining surface of the semiconductor die and the second metal region, wherein a minimum thickness of the first soldered joint is greater than a maximum thickness of the second soldered joint.

Abstract: A batch soldering method includes providing a first passive device, arranging the first passive device on a first metal region of a substrate with a region of first solder material between the first passive device and the substrate, providing a semiconductor die, arranging the semiconductor die on a second metal region of the substrate with a region of second solder material between the semiconductor die and the substrate, and performing a common soldering step that simultaneously forms a first soldered joint from the region of first solder material and forms a second soldered joint from the region of second solder material. The common soldering step is performed at a soldering temperature such that one or more intermetallic phases form within the second soldered joint, each of the one or more intermetallic phases having a melting point above the second solder material and the soldering temperature.
