Ball grid array integrated circuit package

摘要

A ball grid array integrated circuit package which has a plurality of elliptical shaped solder pads located on a substrate of the package. Routing traces are connected to the apexes of the elliptical shaped solder pads. Connecting a routing trace to the apex of an elliptical shaped solder pad reduces the stress points on the trace/pad interface. Vias may be coupled to the solder pads and the routing traces. The vias are located at the apexes of the elliptical shaped solder pads to reduce the stress points of the substrate.
