TMA - Thermo Mechanical Analysis

TMA of Plastic encapsulated microelectronic and other electronic materials (PCB,...) are basic techniques to determine materials characteristics and final device performances/reliability.
The TMA (The thermomechanical analysis) support avoiding problems at the design and fabrication stages, and also foresee anomalies related to the deformation of materials with temperature and the related failure mechanims. 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, being a perfect tool to assess plastic COTS devices.
