Abstract:
In this paper, a stress model is proposed and this model well explains the stress induced failure mechanism of this MEMS micro-injector. An effective solution and optimize design to enhance the robustness of ink chamber design in a MEMS micro-injector is also demonstrated to achieve MEMS printing head production yield over 99%.
