Stuctural analysis of lead frame design of dual row quad flat no lead package (QFN) using ansys / Nur Atiqah Mohamad Maksom

This study presents the mechanical characteristics on the stress of the Dual Row Quad Flat No Lead (DR-QFN) of a 44 lead DR-QFN package on the staggered lead frame design and 48 lead DR- QFN package on the inline lead frame design. The steadystate structural analysis of DR-QFN package with different...
