In some cases these failures can lead to catastrophic failure. The phenomenon of electrochemical migration is one of the most dangerous failure mechanism which usually results in short resistive circuits. In this paper electrochemical migration (ECM) failure phenomena is be investigated which was real-time monitored by the measurements of electrical parameters of conductor patterns with immersion Ag and immersion Ag finish coated with Sn60Pb on Printed Wiring Boards (PWB.) Highly Accelerated Stress Test (HAST) and Thermal Humidity Bias (THB) tests were carried out and Mean Time To Failure (MTTF) comparison was investigated between immersion Ag and immersion Ag coated with Sn60Pb.Only preliminary investigations were presented in order to determine the steps of the full ECM process on different substrates, surface finishes, solder alloys under various climatic conditions. The key findings were that the MTTFs during HAST tests were significantly shorter than in case of THB tests.","PeriodicalId":337429,"journal":{"name":"2009 32nd International Spring Seminar on Electronics Technology","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-05-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130318722","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Actual progress in the industrial application of piezoelectric materials such as Lithium Niobate (LiNbO3), Langasite (LGS), Lanthanum-Gallium Silicate La3Ga5SiO14 and Gallium Orthophosphate (GaPO4), allows the manufacturing of devices with performances, which overcome the limits obtained with quartz crystals. One of the most important applications of SAW microdevices is passively, wirelessly interrogating systems. Today, GaPO4 with its properties is by far the best suited piezoelectric material to be used in sensor applications for machine monitoring and pressure measurements, at high temperatures. SAW microdevices based on GaPO4 operate at temperatures of up to 800°C. In this paper is presented a short introduction regarding the actual level of SAW microdevices development. We discuss our investigations as a comparative study of GaPO4, Langasite, and LiNbO3, regarding their properties. Each has unique strengths and weaknesses giving advantages in different applications. Conclusions regarding trends in the development of SAW sensor devices with novel materials are presented in the end of the work.","PeriodicalId":337429,"journal":{"name":"2009 32nd International Spring Seminar on Electronics Technology","volume":"48 11","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-05-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"120822130","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The portable device is used to measure sensors placed inside and outside of a hydro-energetic building (dams), where the ambient temperature range is between —20°C÷35°C. The self-heating phenomenon of electronics components cumulated with the ambient temperature increases the packaging temperature which affects the device measurement procedure. The usual electronic component that is affected by temperature variation is the resistor and the analog to digital convector, but the most significant error is caused by resistors. A through hole resistor used as a reference, with temperature coefficient of 10ppm/°C and tolerance of 1%, generates a measurement temperature error of 2.5 °C - with a 0.1% tolerance the error is reduced by 10 times. Modeling the temperature resistor behavior, the accuracy of measurement device can be less that 0.02°C. To establish the resistor temperature model a thermal imaging analyze is been made and using a microcontroller as a central unit, the temperature error can be eliminate by soft. The PCB components placement and positioning can be also optimized using the thermal image.","PeriodicalId":337429,"journal":{"name":"2009 32nd International Spring Seminar on Electronics Technology","volume":"123 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-05-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134179743","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These concerns ranged from the waste and pollution due to mining and heavy manufacturing to emissions from the automobile and fossil fuel power plants. Now the proliferation of electronics products, their manufacture and disposal are posing additional threats to the fragile balance of the Earth's eco systems. Nevertheless, electronics can also be the solution to many of our current and future environmental and energy related problems. The environmental threats from electronics can be significantly reduced or eliminated through consciously environmentally responsible choice of materials, technology, design, manufacture, distribution, usage, and end-of-life disposal. In a similar way the application of electrical and electronics technologies and devices for power generation, electric and hybrid automobiles and solid-state lighting can significantly positively contribute to reducing mankind's carbon footprint and improve our environment. Thus, consciously and demonstrably, electronics technologies, devices and applications are making major contributions through the removal of toxins and pollutants; innovative materials enable reduction in use of other materials; new electronics energy sources will become the long-term major sustainable sources; solid state lighting is decreasing the consumption of energy whilst providing improved illumination.
