Abstract:
1. An electrical component comprising: a substrate having a surface; component structures connected to the surface of the substrate; and solder metal platings electrically connected to the component structures; wherein the substrate is electrically and mechanically connected in a flip chip arrangement to a carrier via connections formed by solder bumps, the solder bumps mating to the solder metal platings; wherein at least one of the solder bumps is on a first solder metal plating; wherein the first solder metal plating has first and second dimensions, the first dimension being larger than the second dimension, the first and second dimensions being along a same surface that is parallel to the surface of the substrate; and wherein the first solder metal plating is elliptical in shape, circular in shape, or rectangular in shape containing only rounded ends.
