プリンテッドエレクトロニクス製品化を牽引する『第3世代』スクリーン印刷

抄録

Unlike other general printing methods, because the mask inking mechanism in screen printing is based on the so-called "first in, first out" principle, the ink in the mask is unlikely to dry out. Thus, screen printing is able to consistently print the high-viscosity, functional pastes used in electronics. In order to print with high precision, a screen with a high mesh count and fine wire diameter is required, but, until now, such screen meshes have been problematic in terms of insufficient strength. Recently, however, the "non-distortion screen mask" was developed and commercialized. This is a screen with an extremely high mesh count of 650 and 2.5 times the strength of conventional screen meshes. This "non-distortion screen mask" is ushering in the "third generation" of screen printing, which will allow anyone to achieve high-quality screen printing; this will contribute toward speeding up the commercialization of printed electronics.
