  • Patent number: 12610828
    Abstract: A lead frame includes a base comprising a bearing surface for bearing a chip. The bearing surface includes a soldering region, with a solder layer arranged in the soldering region. The solder layer is configured for fixing the chip on the bearing surface. The lead frame includes a groove provided on the bearing surface in a thickness direction of the base. The groove is located outside the soldering region and surrounds at least part of the soldering region along the outer periphery of the soldering region for receiving solder paste overflowed from the soldering region. A depth of the groove is based on a thickness of the base. A packaging structure including the lead frame and a packaging method using the lead frame are also provided.
