  • Patent number: 11908826
    Abstract: A clip preform includes a die contact portion and an aligner structure. An intermediate portion connects the die contact portion to a lead contact portion in the aligner structure. The die contact portion is configured to contact a semiconductor die. The aligner structure is configured to attach the lead contact portion to a lead post. The die contact portion, the intermediate portion, and the aligner structure form a structure of a primary clip for connecting the semiconductor die to the lead post. The clip preform is severable by removing parts of the die contact portion and the intermediate portion of the clip preform to form a secondary clip for connecting the semiconductor die to the lead post. The aligner structure, a remaining part of the die contact portion, and a remaining part of the intermediate portion of the clip preform form a structure of the secondary clip.

  • Publication number: 20220020740
    Abstract: Described implementations provide wireless, surface mounting of at least two semiconductor devices on opposed surfaces of a leadframe, to provide an isolated, three-dimensional (3D) configuration. The described implementations minimize electrical failures, even for very high voltage applications, while enabling low inductance and high current. Resulting semiconductor device packages have mounting surfaces that provide desired levels of isolation and insulation, while still enabling straightforward mounting techniques, such as soldering, as well as high levels of thermal reliability.

  • Patent number: 10741480
    Abstract: A semiconductor package assembly has a leadframe that includes a socket member into which solderless pins may be inserted as interconnects to an external component. The cost of manufacturing such a leadframe is reduced without sacrificing the ability to make solderless connections with external components such as PCBs. For example, instead of using a hard material that requires two stamping tools, the leadframes with female sockets may be made using softer copper-based materials. Moreover, the width of such leadframes is significantly smaller than the width of a leadframe with the press-fit pins included. Such a reduced width may further reduce manufacturing costs.

  • Patent number: 8426953
    Abstract: A two tier power module has, in one form thereof, a PC board having upper and lower traces with an opening in the insulating material that contains a power device which has upward extending solder bump connections. An upper leadframe is mounted on the solder bumps and the upper tracks of the PC board. Vias in the PC board connect selected upper and lower traces. A control device is mounted atop the leadframe and wire bonded to the leadframe, and the assembly is encapsulated leaving exposed the bottom surfaces of the lower traces of the PC board as external connections. In another form the PC board is replaced by a planar leadframe and the upper leadframe has stepped sections which make connections with the planar leadframe, the bottom surfaces of the planar leadframe forming external connections of the module.
