Development of heat and mass transfer complex theoretical-numerical-experimental methodology for climate control inside electronic systems


Project no.: 09.3.3-LMT-K-712-19-0231

Project description:

Uncontrolled climate in the electronic systems causes 40 % of the total electronics failures, such as acceleration of corrosion, leakage currents, alternation of material properties, short or open circuits caused by electrochemical metal migration, formation of electrically conductive aqueous paths on surfaces and interfaces. Presently, the design of electronics systems and its enclosures with regard to climate control is often based on years of experience, rather than scientific knowledge. Today, such numerical models based on the proper governing differential equations do not exist primarily due to the lack of deep understanding of complex transfer processes in the electronic systems, namely, heat and mass transfer, phase change and water layer formation, from which such theoretical-numerical models could be developed. Hence, the aim of the project is to build up the necessary theoretical base and to develop the numerical methodology for climate prediction and control in the electronic systems.

Project funding:

This research project is funded by the European Social Fund according to the 2014–2020 Operational Programme for the European Union Funds’ Investments, under measure’s No. 09.3.3-LMT-K-712 activity “Promotion of postdoctoral fellowships studies”.

Project results:

The research results will be presented in two high impact factor scientific journal papers and at least two conference papers. The results will summarize the importance and influence of the phase change processes for heat and mass transfer in the electronics systems.
Furthermore, the developed and validated theoretical-numerical methodology will be applied for the prediction and control of electronic systems climate. A developed model will help electronics engineers to better predict and find optimal designs and humidity control solutions at system level. This methodology will be the basis for designing a more reliable electronics systems.
