This twin bubble back shooting structure can reduce the problems of crosstalk and satellite droplets. We demonstrated that the SiN layer in-between the heater and the ink has dominant effect in optimizing the thermal efficiency of this structure. Besides, a SiN layer of 0.8 um in thickness is proven for good thermal efficiency as well as good printing quality. By using this simulation tool, the layer thickness effect on bubble nucleation is well illustrated and optimized to achieve heater structure design optimization. | | ISBN: | 1-4200-6184-4 |
