ROM-FOM Interface Optimization for Efficient Thermomechanical Simulations of Electronic Components

Model order reduction techniques are developed and utilized to make numerical simulations more efficient. The use of Reduce Order Models (ROM) also enables data exchange with external parties without disclosing the sensitive information present in a Full-Order Model (FOM). It is crucial to optimize for both the efficiency and accuracy of a ROM...

A Continuously Updated Package-Degradation Model reflecting Thermomechanical Changes at Different Thermo-Oxidative Stages of Moulding Compound

Moulding compounds used for encapsulating electronics typically occupy a large portion of package volume and are most exposed to the external environment. Under harsh conditions such as high temperature, humidity, and mechanical vibrations, constituent materials of electronic components degrade, resulting in a change in their thermal, mechanical...

Digital Twin-Based Hybrid PHM Framework for Monitoring Package-Level Degradation

Digital Twin can be broadly described as a continuously updated virtual representation of an object, system, or process which replicates all phases in the lifecycle of its physical counterpart. Originally conceptualized in 2003 [1], the term `Digital Twin' came into existence after it first appeared in NASA's roadmap in 2010 [2]. The concept...
