Abstract
Paste roll state is an important factor for the robust printing process, but there are only few reports related to it. In this study, we investigated a squeegee shape to improve the continuous printability by stabilizing the paste roll behavior. Against this goal, we estimated that the issue is the weak paste flow and the decrease in the paste amount. Using fluid analysis, we developed the squeegee shape that can suppress the decrease in the paste amount with keeping the paste flow strong. As a result, we achieved to improve the continuous printability 5 times higher than a general flat squeegee.
