- Abstract
- A slot coating process has been recently applied to the production of electric circuits due to its fast production rate and low cost. The prediction of minimum coating thickness or coating stability has been performed by using a viscocapillary model. However, the results are inaccurate for a high speed coating because it neglects inertia effects arising in the high speed coating condition. Thus, we modified the viscocapillary model to propose an inertia-capillary model that includes the inertial effects. As a result, this new model can be applicable to a Reynolds number of an order higher than the viscocapillary model.
