A device, comprising: a leadframe feature (310, 322, 710, 722) having a first surface, a second surface opposed to the first surface, and a vent hole (336, 736) formed between the first surface and the second surface; and a molding compound partially encapsulating the leadframe feature (310, 322, 710, 722), characterized by fill material comprising solder and sealing the vent hole (336, 1136), wherein the vent hole (336, 736) comprises: a first opening extending from the first surface toward the second surface to a first depth that is less than a thickness of the leadframe feature (310, 322, 710, 722); and a second opening extending from the second surface toward the first surface to a second depth that is less than the thickness of the leadframe feature (310, 322, 710, 722), but that is large enough for the second opening to intersect the first opening, wherein a first vertical central axis of the first opening and a second vertical central axis of the second opening are horizontally offset from each other by a distance in a range from 10 to 90 percent of a diameter of the first opening, and wherein a constricted portion of the vent hole (336, 736) corresponds to an intersection of the first opening and the second opening. a leadframe feature (310, 322, 710, 722) having a first surface, a second surface opposed to the first surface, and a vent hole (336, 736) formed between the first surface and the second surface; and a molding compound partially encapsulating the leadframe feature (310, 322, 710, 722), characterized by fill material comprising solder and sealing the vent hole (336, 1136), wherein the vent hole (336, 736) comprises: a first opening extending from the first surface toward the second surface to a first depth that is less than a thickness of the leadframe feature (310, 322, 710, 722); and a second opening extending from the second surface toward the first surface to a second depth that is less than the thickness of the leadframe feature (310, 322, 710, 722), but that is large enough for the second opening to intersect the first opening, wherein a first vertical central axis of the first opening and a second vertical central axis of the second opening are horizontally offset from each other by a distance in a range from 10 to 90 percent of a diameter of the first opening, and wherein a constricted portion of the vent hole (336, 736) corresponds to an intersection of the first opening and the second opening. a first opening extending from the first surface toward the second surface to a first depth that is less than a thickness of the leadframe feature (310, 322, 710, 722); and a second opening extending from the second surface toward the first surface to a second depth that is less than the thickness of the leadframe feature (310, 322, 710, 722), but that is large enough for the second opening to intersect the first opening, wherein a first vertical central axis of the first opening and a second vertical central axis of the second opening are horizontally offset from each other by a distance in a range from 10 to 90 percent of a diameter of the first opening, and wherein a constricted portion of the vent hole (336, 736) corresponds to an intersection of the first opening and the second opening.
