Modeling of extrusion coating for applications in electronics manufacturing

— This paper focuses on the development of a model of the extrusion coating process that can be used to generate an automated (as opposed to manual) procedure for determining the control setpoints for a desired deposition thickness and range of deposition materials. This model includes the dynamics of the bead formation process and the bead variation during the coating. The “bead” refers to the deposition material that collects in front and under the die head as the substrate is moved beneath it. Understanding and modeling the dynamics of the bead process as a function of the control‐variable settings is crucial in obtaining an automated procedure for setpoint determination in extrusion coating.
