    Abstract: A method for aligning interconnects that includes trimming and forming a frame of strips of interconnects. The frame of strips of interconnects includes interdigitated pins. The method also includes removing siderails from the frame of strips of interconnects to provide an array of strips of interconnects. The method includes aligning a first set of strips of interconnects in the array of strips of interconnects such that pins of the first set of strips of interconnects are aligned with pins of a second set of strips of interconnects in the array of strips of interconnects. A strip of interconnects of the first set of strips of interconnects are adjacent to a strip of interconnects of the second set of strips of interconnects to provide an aligned array of strips of interconnects. The method further includes singulating the aligned array of strips of interconnects.

    Abstract: An electronic device includes a package structure with opposite first and second sides spaced apart along a first direction, opposite third and fourth sides spaced apart along a second direction, opposite fifth and sixth sides spaced apart along a third direction, the first, second, and third directions being orthogonal to one another. A set of first leads extend outward from the first side along the first direction, a set of second leads extend outward from the second side along the first direction, and a thermal pad includes a first portion that extends along a portion of the fifth side, and a second portion that extends along a portion of the third side to facilitate cooling and visual solder inspection when soldered to a host printed circuit board.

    Abstract: A leadframe (100) comprises a frame (101) of sheet metal in a first planar level, where the frame has metallic leads (110) and a first metallic pad (120) extending inward from the frame, and the first pad is tied to the frame by first metallic straps (120a). The leadframe further has a second metallic pad (130) in a second planar level parallel to and spaced from the first level, where the second pad is tied by second metallic straps (132) to the frame. In addition, the leadframe has a third metallic pad (140) in a third planar level parallel to and spaced from the second level and additively from the first level, where the third pad is tied by third metallic straps (131) to the second pad.
