source: Brno University of Technology CEITEC, AVX Czech Republic s.r.o., EPCI e-Symposium Abstract: Tantalum capacitors have been the preferred capacitor technology in long lifetime electronic devices thanks to the stability of its electric parameters and high reliability. However, long time application of elevated temperature and high electric field can result in capacitor leakage current increase in time. In this paper the effect of ions...

source: ASRC Federal Space and Defense (NASA), EPCI e-Symposium Abstract: Exposure of chip MnO2 tantalum capacitors to humid environments might result in increased ESR, leakage currents, and first turn-on failures.  However, there is a lack of literature data on the effect of moisture on reverse bias behavior of the parts. The presence of moisture can also result in pop-corning when a high water vapor...

source: Würth Elektronik eiSos GmbH, EPCI e-Symposium Abstract: Our environment is changing and everything is becoming “electronified”. Our glasses, our hand gloves, shirts, shoes etc., can be connected already today with our smartphones and can send commands to the machinery surrounding us. We want this comfort, and we are all looking forward to having Smart Homes.   Chip manufacturers have introduced a new generation...

source: Alter Technology, ESA ESTEC, EPCI e-Symposium Abstract: During the last decade, a growing number of applications demanding higher power electrical consumption have emerged in some industrial sectors such as in the military, automotive or space ones. Consequently, electrical components with higher temperature range and rating voltage operation are needed. In addition, the good thermal characteristics of Silicon Carbide (SiC) and Gallium Nitride (GaN)...

Active layer is deposited on a flexible substrate by new deposition technique called Aerosol Jet. The deposition technique remove deficiency of today’s common used deposition technique, where it is very difficult to deposit a thin homogeneous layer of carbon nanotubes. The...

Thanks to embroidery, which has been recognized as one of the most promising manufacturing techniques for integrating antennas into clothing, the antennas are more robust, more flexible, fully washable and comfortable for...

source: RICE, FEE, University of West Bohemia in Pilsen, EPCI e-Symposium Abstract: Wearable electronics and smart textiles is rapidly developing area currently. An integration of electronic components and systems directly on/into textile substrates leads to the development of promising new technologies among which it is possible to include printing of passive electronic components and/or embroidering of passive electronic components directly onto textile substrates using...

source: Heraeus, EPCI e-Symposium Abstract: The major use of polymer aluminum and tantalum capacitors is for low voltage consumer electronics. The development of conductive polymer dispersions has extended the voltage range of polymer capacitors up to 125 V in the last years and opened the door for high reliability applications like automotive. We present the next generation of polymer aluminum capacitors reaching rated voltage...

source: RICE, FEE University of West Bohemia, EPCI e-Symposium Abstract: Aerosol Jet is a selective direct writing deposition technology. It generates aerosol from an inserted ink and aerodynamically focuses this aerosol in a print head. This allows the aerosol beam to be focused to the distance (between the tip of the deposition nozzle and a substrate) up to 15 mm. Thanks to that, the...

source: Brno University of Technology CEITEC, EPCI e-Symposium Abstract: Degradation of supercapacitor (SC) is analyzed by accelerated aging test. Evolution of SC parameters is determined before the aging test, and during up to 8 x 105 cycles of both 75% and 100% energy cycling. Capacitance fading, equivalent series resistance (ESR) increase, and leakage current trend are analyzed for off-the-shelf CapXX SC.   Presented model...
