초록

Recently, inkjet technology has emerged as one of the most powerful tools for patterning electronics devices, such as large area display applications, RFID, PCB patterning, etc. By using the Inkjet technology, the droplet speed as well as the size can be controlled precisely. In this paper, the relationship between waveform and droplet size will be investigated by means of experiment. Also the relationship between inkjet speed and droplet size will be discussed. It was shown from experimental results that ink droplet size from the nozzle diameter of $50{\mu}m$ can be varied from 37 to $58{\mu}m$ by modifying the inkjet waveform when the speed of the droplet is 1m/sec. Finally, experimental results indicate that small drops are more difficult to generate than large drops since the jetting conditions for making small drops are sensitively affected by the dwell time variation.
