  • Publication number: 20230361008
    Abstract: An electronic device includes a molded package structure and a conductive lead partially exposed outside the package structure, the package structure having lateral sides extending at an angle that is greater than 15 degrees and 25 degrees or less to facilitate mold cavity filling during package molding and mitigate mold voids in the electronic device. A method of fabricating an electronic device includes attaching a die to a lead frame, electrically coupling a conductive terminal of the die to a conductive lead and performing a molding process using a mold having cavity sidewalls with a draft angle greater than 15 degrees and 25 degrees or less to form a package structure that encloses the die and partially encloses the conductive lead.

  • Publication number: 20220223503
    Abstract: A method includes attaching semiconductor dies to die attach pads of first and second columns of the lead frame; enclosing the semiconductor dies of the respective columns in respective first and second package structures; trimming the lead frame to separate respective first and second lead portions of adjacent ones of the first and second columns of the lead frame; moving the first columns along a column direction relative to the second columns; and separating individual packaged electronic devices of the respective first and second columns from one another.

  • Patent number: 9141157
    Abstract: A molded system (100) has a plurality of components (110, 120, 130) attached to a carrier (101), one of the components being an object (110) of irregular thermal capacitance. For example, carrier (101) may be a QFN/SON-type leadframe and object (110) an inductor of high thermal capacitance. The surface of the object is sealed with a hardened polymeric layer (220) of high thermal resistance, whereby the layer (220) thermally insulates the object (110) and inhibits the transport of thermal energy between the object and the system. System (100) has molding compound (140) encapsulating the carrier and the attached components including the object (110) and the polymeric layer sealing the object's surface.
