Abstract:
1. A substrate with a via and pad structure connecting a surface mount component to conductive layers of the substrate, comprising: a surface mount component, wherein the surface mount component includes a package having an upper surface with solderable terminal sides and a terminal end; a substrate; a plated via connected to the conductive layers; a solder mask surrounding the plated via; and a conductive pad with a conductive trace connected to the plated via, wherein the solder mask exposes a part of the conductive pad that extends beyond the solderable terminal sides of the surface mount component to increase solder formation between the conductive pad and the solderable terminal sides and to reduce solder formation at the first plated via, wherein the solder mask covers a part of the conductive pad that extends beyond the solderable terminal end and reduces solder formation at the terminal end of the surface mount component.
