| Abstract | The physical mechanism of contact fluid dispensing is very complicated and controlling of contact fluid dispensing process is a known difficult problem in microelectronic packaging. But there has been little mechanism research on contact fluid dispensing and nearly all control methods of dispensing process are basically based on black box model. This paper puts forward an idea of phasing study fluid dynamic evolvement mechanism in contact fluid dispensing dot and farther dividing the fluid dynamic evolvement process into four different phase from the view of fluid dynamics. Directed by the idea of phasing study and by adopting the high speed imaging system as main study means, an experimental system for the research of the fluid dynamic evolvement mechanism of contact dispensing dot is being developed. The experimental system consists of mainly mechanical system, control and measurement system, high-speed imaging system and pneumatic system, and it has a lot of features that are specially designed for fulfilling the requirement of the phasing study method. The experimental research of the fluid dynamic evolvement of fluid contact dispensing dot process will let us acquire new knowledge about the fluid dynamics mechanism of contact dispensing dot, which is lack at present, understand about more parameters' influences on the dispensing process, and make process control models be more accurate and less black box. |

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.
