Abstract: A dual footprint mounting package for a surface mount power converter modules and its method of manufacture. Castellated regions are formed on the edge of the component package using the appropriate sized drill or milling bit. Edge plating is applied to the castellated surfaces to create edge pads. The edge plating provides electrical continuity between the edge pads and the SMT pads. Solder mask, or other materials, is applied to prevent solder from wicking between each SMT pad and its respective edge pad. Such component may be attached to a larger device PWB using either the edge pads or the SMT pads, or may even be attached using a combination of the two, such as in the event of a pad failure or other defect.
