Abstract

An electrical component includes a substrate, component structures on the substrate, and solder metal platings electrically connected to the component structures. The substrate is electrically and mechanically connected in a flip chip arrangement to a carrier via connections formed by solder bumps. The solder bumps mate to the solder metal platings. At least one of the solder bumps is on a first solder metal plating. The first solder metal plating has first and second dimensions, where the first dimension is larger than the second dimension.
