The lead via can include via lateral sides defined by first concave portions and the lead protrusion can include protrusion lateral sides defined by second concave portions. The substrate encapsulant covers the first concave portions at a first side of the substrate but not the second concave portions so that the lead protrusion protrudes from the substrate encapsulant at a second side of the substrate. An electronic component can be adjacent to the first side of the substrate and electrically coupled to the conductive structure. A body encapsulant encapsulates portions of the electronic component and the substrate. The lead can further include a lead trace at the second side of the substrate.
