摘要:
A metal tab die attach paddle (DAP) disposed between the lead frame and a power device die in a power device package reduces the stress exerted on the semiconductor power device die caused by the different coefficients of thermal expansion (CTE) of the semiconductor power device die and the lead frame. In addition the power device package substantially prevents impurities from penetrating into the power device package by increasing the surface creepage distance of a sealant resulting from the metal tab DAP and an optional swaging of the lead frame.
