  • Patent number: 8304868
    Abstract: A pallet (501) supporting a half-etched leadframe with cantilever-type leads (403) without metallic supports during the step of attaching components (510) to the leads in order to assemble an electronic system. After assembly, the pallet is removed before the molding step that encapsulates (601a) the components on the leadframe and mechanically supports (601b) the cantilever leads. The pallet is machined from metal or inert plastic material, tolerates elevated temperatures during soldering, and is reusable for the next assembly batch.

  • Patent number: 8154109
    Abstract: A lead frame (410) including a die pad (100) for mounting at least one integrated circuit (405) thereon and a plurality of lead fingers (413). The die pad (100) includes a metal including substrate (105) having a periphery that includes a plurality of sides (111-114), an intersection of the sides forming corners (115). A first plurality of grooves including least one groove (106) is formed in a top side surface of the substrate and is associated with each of the corners (115). The groove (106) has a dimension oriented at least in part at an angle of 75 to 105 degrees relative to a bisecting line (118) originating from the corners (115). A lead-frame-based packaged semiconductor device (400) includes a lead frame (410) including at least one metal comprising die pad (418) and a plurality of lead fingers (413) around the die pad (418). At least one integrated circuit (405) is mounted on the top surface of the die pad (418), and electrically connected to the plurality of lead fingers (413).

  • Patent number: 8053876
    Abstract: According to an embodiment of the invention, a system, operable to facilitate dissipation of thermal energy, includes a mold compound, a die, a first lead frame, and a second lead frame. The die is disposed within the mold compound, and in operation generates thermal energy. The first lead frame is disposed at least partially within the mold compound and is operable to facilitate transmission of a signal. The second lead frame is disposed at least partially within the compound, at least partially separated from the first lead frame, and is operable to facilitate a dissipation of thermal energy.

  • Patent number: 7488623
    Abstract: An integrated circuit chip packaging assembly having a first and second package side. An integrated circuit chip has a substrate side and an active circuit side. The chip includes integrated circuit devices formed on the active circuit side. The active circuit side of the chip is on the first package side. The die pad has at least one runner member extending therefrom, which may be bent toward the first package side. The active circuit side of the chip is attached to the die pad. The die pad is on the first package side relative to the chip. The package mold compound is formed over the die pad, at least part of the chip, and at least part of the runner member(s). At least part of the substrate side of the chip and/or at least part of the runner member(s) may not be covered by the package mold compound.
