Abstract
In this study, we have been investigating printing characteristics of pastes used for screen printing to form electrode patterns on substrates. Influences of surface treatment of particles in the pastes on the characteristics and their printability are mainly discussed in this report. A stencil with a small hole was utilized as a model of the screen and the pastes were printed to a substrate through the hole. Shapes of the pastes adhered to the substrate was measured. Yield behavior in elongational deformation was observed in the case with low separating velocity. In our experimental conditions, the influences of surface treatment were not so large in the case with high separating velocity.
