Consistent with one or more embodiments, lead fingers on a leadframe substrate each have a locking structure that secures the lead finger in place relative to the substrate. The lead fingers provide a location to attach a bond wire to an integrated circuit, and connect the bond wire to terminals at a perimeter of the leadframe. The locking structure and arrangement of the lead fingers mitigate issues such as cracking or breaking of a solder connection of the bond wire to the leadframe, which can occur due to thermal expansion and contraction."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Lead finger locking structure","description":"Various aspects are directed to apparatuses, systems and related methods involving the mitigation of issues relating to thermal expansion and contraction of lead fingers of an integrated circuit packa","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9824980","license":"CC-BY-4.0-like","license_terms":"AI-generated analysis on this page (summary, layman_explanation, technical_analysis, business_analysis, faqs) may be reused with attribution and a visible link back to the canonical URL above.
