Abstract Recently, microchannel jetting dispenser technology has been widely used in many industrial applications such as an assembly of micro-electronics. The microfluidic channel of the dispensing needle affects significantly the jetting dispensing process. In order to increase the insufficiency and instability of contact inkers, the novel microchannel structure with the diamond film coating was proposed in this paper. The surface morphology, structure and hardness of the TiAIN films have been observed. The TiAIN film coating can enhance the tightness and stability and shows the improvement in the non-contact dispensing process. The experimental investigation about the effect of the nozzle with TiAIN film coating was provided in this study.
