A　finite　element　model　which　contains　one　sixth　of　the　IGBT　module　based　on　a　real　test　chip　of　IGBT　module　is　established　to　investigate　the　temperature　and　stress　distribution　of　different　shape　bonding　wire.　The　finite　element　(FE)　analysis　which　coupled　electro-thermal　and　thermal-mechanical　are　conducted　using　commercial　software　ABAQUS.　The　thermal　performance　and　stress　distribution　of　IGBT　module　with　three　kinds　of　bonding　wire　respectively　shape,　named　Arc-shape,　Parabolic　shape　and　Trapezoidal　shape　are　discussed.　The　results　show　that　the　temperature　distribution　of　three　kinds　of　bonding　wire　is　similar,　but　the　stress　of　bonding　wire　is　quite　different.　Parabolic　shape　bonding　wire　has　the　minimum　stress　76.73　MPa.　Trapezoidal　shape　bonding　wire　has　the　maximum　stress　106.1　MPa.
