This improves the signal quality after 10 m transmission compared to a passive electrical cable significantly and enables even longer cable lengths or higher transmission rates. At the same time we developed a compact package of both the optical sub-assembly and its adjoining control ICs that fits inside the cable connector. We outline the package assembly and present basic transmission characteristics, as well as confirm 1080p video transmission over 10 m.","PeriodicalId":174050,"journal":{"name":"2012 2nd IEEE CPMT Symposium Japan","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115565064","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}

Today, represented by Smart-phones and Tablet PC's, highly functional electronic devices continue to evolve, although manufacture has shifted overseas. In overseas manufacture, from the perspective of factory labor technical ability, plating stability, and in-plane uniformity among other factors, insoluble anode copper sulfate plating prevails. However, a known demerit of insoluble anodes, as opposed to soluble anodes, is the larger consumption of additives. This may be inherent to the electrode material, for which we investigated and report here. As a result of the comparison of immersed potential of each material with the additive consumption, we found that consumption increased as the immersion potential of the electrode material increased. This suggests additive consumption significantly occurs at the anode. Meanwhile, no correlation between dissolved oxygen concentration and additive consumption was observed, despite oxygen concentration differences during plating for each anode.","PeriodicalId":174050,"journal":{"name":"2012 2nd IEEE CPMT Symposium Japan","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123727188","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}

Additionaly, it is also found that the waveguides with GI-type circular cores is sensitive to the optical confinment in the cladding: low power cladding modes largely decreases the mode conversion.","PeriodicalId":174050,"journal":{"name":"2012 2nd IEEE CPMT Symposium Japan","volume":"23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126485647","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}

However, the study of the conductive mechanism between electrodes of parts has not been elucidated yet. The reason is that the flat surface (2D) observation is usually used, though the actual dispersion of fillers is the three dimension (3D). In this paper, we observed 3D dispersion and 3D conductive pathway by FIB-SEM which repeats porishing and observation. In addition, thermal conduction and electric conduction are analyzed by this observation result. Then, the electric and thermal interface resistance can be calculated by the comparison of analysis and experiment.

In 2011, the EM tests were performed on 80μm pitch solder capped Cu pillar bump interconnections and the effects of Ni barrier layers on the Cu pillars and the pre-formed intermetallic compound (IMC) layers on the EM tests were studied. The EM test conditions of the test vehicles were 7-10 kA/cm2 at 125-170°C. The Cu pillar height was 45μm and the solder height was 25μm. The solder composition was Sn-2.5Ag. Aged condition for pre-formed IMCs was 2,000 hours at 150°C. It was shown that the formation of the pre-formed IMC layers and the insertion of Ni barrier layers are effective in reducing the Cu atom dissolution. In this report, it is studied that which of the IMC layers, Cu3Sn or Cu6Sn5, is more effective in preventing the Cu atom dissolution. The cross-sectional analyses of the joints after the 2,000 hours of the test with 7kA/cm2 at 170°C were performed for this purpose. The relationship between the thickness of Cu3Sn IMC layer and the Cu migration is also studied by performing the current stress tests on the joints with controlled Cu3Sn IMC thicknesses. The samples were thermally aged prior to the tests at a higher temperature (200°C) and in a shorter time (10-50 hours) than the previous experiments. The cross-sectional analyses of the Sn-2.5Ag joints without pre-aging consisting mostly of Cu6Sn5, showed a significant Cu dissolution while the Cu dissolution was not detected for the pre-aged joints with thick Cu3Sn layers. A large number of Kirkendall voids were also observed in the joints without pre-aging. The current stress tests on the controlled Cu3Sn joints showed that Cu3Sn layer thickness of more than 1.5μm is effective in reducing Cu dissolution in the joints.","PeriodicalId":174050,"journal":{"name":"2012 2nd IEEE CPMT Symposium Japan","volume":"46 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115260513","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}
