EMC oxidation under high temperature aging

Inamdar, A.S. (author), Gromala, Przemyslaw Jakub (author), Prisacaru, Alexandru (author), Kabakchiev, Alexander (author), Yang, Yu Hsiang (author), Han, Bongtae (author)

Epoxy molding compound (EMC) is widely used for encapsulating automotive electronics. Among all of the components of an electronic package, EMC is most exposed to the atmosphere, and thus undergoes aging. During high-temperature operation, EMC is oxidized, which alters its mechanical properties, and thus can affect the reliability of electronic...
