| Abstract | This work was performed to investigate the effect of final surface finish of Cu electrodes on the adhesion and reliability of anisotropic conductive films (ACFs) joints. Two different materials, electroless Ni/immersion Au (ENIG) and organic solderability preservatives (OSPs), were selected because these materials has been most commonly used as the final surface finish materials in printed circuit board (PCB) industries. However, the effect of OSPs on the adhesion and reliability of ACF joints has not been studied. Therefore, 1) investigation of the adhesion of ACF/OSP joints, and 2) evaluation of the reliability of ACF/OSP joints were performed in this study. Then, the results of ACA/OSP joints were compared to those of ACF/ENIG to confirm the feasibility and reliability of ACF/OSP joints. Adhesion strengths of ACF/OSP joints were also higher than ACF/bare Cu and ACF/ENIG joints. The fractured site of ACF/bare Cu and ACF/ENIG joints was ACF/metal interface but that of ACF/OSP joints was ACF inside. TEM and FT-IR analyses showed that the OSP coating layer on Cu electrode remained even after ACF bonding and it seemed to play as an adhesion promoter |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
