MT 595:Reliability and Failure of Solid State Devices
This course deals with the electrical, chemical, environmental and mechanical driving forces that compromise the integrity and lead to the failure of electronic materials and devices. Both chip and packaging level failures will be modeled physically and quantified statistically in terms of standard reliability mathematics. On the packaging level, thermal stresses, solder creep, fatigue and fracture, contact relaxation, corrosion and environmental degradation will be treated.
This course provides an in-depth treatment of how to transfer the latest solar thermal technology available to real world applications. It takes the student through the various phases of development of a solar space heating and photovoltaic integrated building; review occupant’s requirements, site analysis, design concept, solar system design, cost estimates, building design, performance predictions and construction. The emphasis of the class is on solar system design methods, economic optimization of solar systems and installation.
This course is an in depth treatment of the principles and practice associated with using solar radiation as an alternate energy source. It examines the science of solar radiation, technologies for its capture and the design principles that are used to apply solar energy in building design.
