Abstract
The pattern constructing technique in screen printing processes is a commonly used manufacturing method, There are many case studies showing the quality improvement by evaluating the transformability of the process or the electrical characteristics of products. This paper is a study showing the improvement which could not be achieved using traditional quality characteristics : the quality items not related with electrical characteristics such as appearance in terms of fraction defective like pin holes. The study was also made to investigate the relationship between appearance and basically requested characteristics such as resistance, linearity, durability or pattern precision, etc.
