Critical factors on the hermetic characteristics of DC/DC power module

The hermeticity of DC/DC power module was analyzed by using finite element thermal analysis software ANSYS to address the critical factors on the reliability issues of glass insulator (or hermeticity).

Description
Summary:The hermeticity of DC/DC power module was analyzed by using finite element thermal analysis software ANSYS to address the critical factors on the reliability issues of glass insulator (or hermeticity). It was found that shell structure parameters, such as the diameter and shape of hole, the thickness of cover and bottom board, especially the boundary constraints make significant influences on the hermitcity of DC/DC during assembly and testing.
