Abstract: Embodiments of the present disclosure are directed to leadframe packages with wettable sides and methods of manufacturing same. In one embodiment, the leads of the leadframe packages have recesses with a curved profile formed therein. The recesses are plated with a solder wettable layer of conductive material that enables solder to flow along the surface during surface mounting of the package to a board, such as a PCB.

Abstract: A leadless semiconductor package includes a package body on a leadframe that includes a die paddle and a plurality of bond pads, none of which extend as far as a lateral face of the body. During manufacture of the package, molding compound is deposited over a face of the leadframe on which the die paddle and bond pads are positioned. After the molding compound is cured, a back side of the leadframe is etched to isolate the die paddle and bond pads, back surfaces of which remain exposed at a back face of the body. During manufacture of the leadframe, a parent substrate is etched to define the die paddle and a plurality of bond pads on one side of the substrate and a plurality of cavities on the opposite face.
