| Abstract | This paper presents the latest innovation in the Inpulse 2 plating system which has been modified to allow reel to reel processing. Reel to reel plating is a standard technology for production of thin core flexible material where the substrate is treated as a continuous roll and where material handling is critical to ensure uniform results. The Inpulse 2 system uses insoluble anodes and a novel copper replenishment system to ensure uniform working conditions. The electrolyte agitation is managed by use of frequency controlled pumps which is critical for thin materials to ensure no surface damage during plating. The electrical contact to the substrate is made by the use of large contact area clamps along one edge of the material to be plated. This combination of features in the equipment allow the use of high production current densities even with flexible base materials with thin conductive layers. The clamping system at one edge of the material allows varying foil widths with no further equipment modifications necessary. The use of segmented insoluble anodes with individually controlled rectification is critical for thin flexible production to ensure optimum copper plated surface distribution. Results are shown from the production system being used to copper plate flexible material which is currently in production. The substrate has laser drilled through vias which are metallised and subsequently through hole copper plated in the reel to reel system. |

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.
