Performance Analysis of an Industrial Inkjet Printing Head Using the 1D Lumped Model

A design approach using a one-dimensional (1D) lumped model was studied and applied to an industrial inkjet printing head design for micro patterning on printed circuit boards. For an accurate analysis, a three-dimensional piezoelectric-driven actuator model was analyzed and its jetting characteristics were applied to 1 Danalysis model. The performance of the 1 D lumped model was verified by comparing measured and simulated results. The developed 1 D model helped to optimize the design and configuration of the inkjet head and could be implemented in the design of multi-nozzle inkjet printing heads to improve the jetting frequency and minimize crosstalk.
