The thermomechanical analysis (TMA) of plastic encapsulated microelectronic, and COTS parts is a fundamental technique to avoid (during the design and fabrication stage) and foresee anomalies related to the deformation of packages with temperature. Thus, this is a very effective tool to disclose and screen out possible reliability concerns related to the thermo-mechanical integrity and stability of the devices.
