Abstract: The micro-liquid dispensing technology which involves absorbing, transferring and redistributing is applied extensively to life science, electronic packaging, rapid manufacturing and other fields. With the development of technologies in these fields, the operation of micro-liquid distribution with higher velocity, precision and smaller dispensing volume is needed more and more in the micro-liquid application fields, which pushes the dispensing technology to a faster, trace, more accurate and flexible direction. Based on introducing the application and requirements of many micro-liquid dispensing technologies used in the field of life science, micro-electronic packaging and rapid manufacturing, the working principle, driving and selection of the applied dispensing methods are contrasted and summarized. The key technologies involved in the development and research of micro-liquid dispensing system and technology are analyzed from the point of driving, control, testing and manufacturing. The development of micro-liquid dispensing technology is prospected, and the results can provide some further reference for the related works.
