| Abstract | Low Temperature Co-fired Ceramic (LTCC) is expected to be widely used as multi-functional substrate for electronic circuit boards and platforms of microsystems. Miniaturised structures such as micro cavities and vias are conventionally formed by mechanical punching or laser machining. These methods, however, encounter difficulties in machining complicated structures, and the minimum dimension is limited by the size of the punching tools or laser beams. This paper reports on micro patterning of LTCC green substrates using micro embossing. The challenges of LTCC embossing include slow material flow during embossing and breakage of embossed substrates during demolding. Hence, the studies on embossing parameters are absolutely important. The process parameters that impact pattern fidelity of LTCC embossing were investigated and optimized in this study. Micro channels with line width as small as 25 mum were formed on LTCC green tapes, and ceramic substrates with embossed micro patterns were obtained after co-firing. The embedded micro channels were obtained as well by laminating the green tapes on the embossed substrates. The results from this work demonstrate that micro embossing is a promising technique for fabricating LTCC-based microstructures. |

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.
