The continuous improvement in engine technology in order to achieve new emission norms have led to an increased amounts of petrol, diesel and soot in the engine oil during engine operation. This dilution causes a fast decrease of the oil properties. Additional, the recommended oil change intervals for automotive engines have continuously been extended over the last few decades. In many cars, this...
In MEMS packaging moisture uptake of packaging materials may lead to severe changes in sensor behavior and package reliability. Knowledge and understanding of the effect of moisture swelling on the overall package deformation and on the sensor system is therefore inevitable for a successful MEMS design and packaging solution. The paper shows a design optimization of a pressure sensor packaging towards...
Microelectronic components are introduced to an increasing number of applications as part of a controlling or monitoring device, as sensors or as means to tracking. Depending on the application, extreme loading profiles may need to be endured such as high temperatures, random vibrations or humid and even wet environments. Absorbed moisture has a plasticizing effect on the physical properties of polymers...
