  • Publication number: 20250006510
    Abstract: In a described example, an example no-lead semiconductor device package includes: a die pad in a central portion of a partially etched leadframe and terminals. The terminals include a device side surface formed in an upper layer of the partially etched leadframe, and a first exterior end in the upper layer; a board side surface formed in a lower layer of the partially etched leadframe extending from the upper layer; a second exterior end in the lower layer, the second exterior end inset from the first exterior end, and an inset portion extending from the first exterior end to the second exterior end. A semiconductor die is mounted to the die pad. Mold compound covers the semiconductor die, the second exterior end of the terminals and the inset portion of the terminals are exposed from the mold compound, with the mold compound extending along sides of the terminals.

  • Publication number: 20240203838
    Abstract: An example integrated circuit (IC) package comprises a DAP having a diamond shape with four corners. The DAP has a first thickness. The IC package has at least one tie bar segment attached to a corner of the DAP. The at least one tie bar segment extends from the DAP to an edge of the IC package. The IC package has at least one contact portion positioned adjacent to a side of the DAP. The at least one contact portions has a second thickness that is greater than the first thickness of the DAP. A semiconductor die mounted on the DAP. A wire bond couples a bond pad on the semiconductor die and a selected one of the contact portions. A molding compound covers the semiconductor die and the bond wire and at least a portion of the DAP and the at least one contact portion.

  • Patent number: 10504801
    Abstract: A method for making integrated circuit (IC) packages includes providing a leadframe strip having a plurality of leadframe units and providing the leadframe strip to an operating station. The operating station is operable to perform one or more tests on the plurality of leadframe units in the making of IC packages. The method includes obtaining a database that has the locations of leadframe units in the leadframe strip stored in the database. The method also includes performing the one or more tests on the plurality of leadframe units and updating the database in response to the results of the testing.
