Such optimization methods help with increasing production effectiveness, decreasing costs and increasing the quality of products. In this paper, fractional factorial experiments are applied to investigate different factors of electrically conductive adhesives modified with silver nanoparticles after the application of mechanical aging and the influence on resistance and non-linearity of joints. The factors considered in the experiment were concentration of silver particles, the size of nanoparticles and the combination of both factors.","PeriodicalId":277579,"journal":{"name":"2012 35th International Spring Seminar on Electronics Technology","volume":"136 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-05-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123254053","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}

Therefore, its physical properties, such as the Young's modulus and the thermal expansion coefficient were broadly investigated. However, no reliable data can be found around 0°C. Therefore, the thermal expansion of the material in the temperature range of -30°C up to +30°C was examined. The thermal expansion was measured via the deflection of appropriate designed structures with the help of an optical microscope. A sealable chamber with a Peltier-element was built and utilized to control the temperature and the ambient atmosphere (N2). It was found, that SU-8 shrinks, when absorbed water vanishes due to an N2 purge. Additionally, the thermal expansion of the SU-8 exhibits a non linear behavior in the range from -20°C to +20°C.","PeriodicalId":277579,"journal":{"name":"2012 35th International Spring Seminar on Electronics Technology","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-05-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129118682","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}

Thereby, the main focus of attention was the thermal behavior during the hot embossing and reflow soldering in a vapor phase reflow soldering oven.

Direct junction temperature determination is not possible and alternative methods have to be developed. Suitable, cheap and reliable method for direct estimation of LEDs' junction temperatures during operating of lighting equipment is proposed. It is realized by employing the temperature dependence of LEDs' forward voltage drop. Two different types of LEDs have been investigated at various ambient conditions (air temperatures from 20°C to 45°C) and different current values through LEDs - from 350 mA to 600 mA. Recommendations concerning calibrations, calculations and junctions' temperatures evaluations are presented. Developed method allows achieving of reliable results “in situ” for thermal performance of LEDs using non expensive experimental equipment.","PeriodicalId":277579,"journal":{"name":"2012 35th International Spring Seminar on Electronics Technology","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-05-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115787536","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}
