Abstract

Domestic display the status of the industry is growing day by day. However, in large part due to lack of core technology and core materials are imported from abroad and Free continuing cost pressures in the display industry as a cost savings for the new method is required. Today, large open world markets and the memory of electronic products in Korea, cpu and display markets such as semiconductor chip market is strong. Semiconductor chips, circuit line widths of several tens nm is very high enough density, it was part of a family of very high performance can be seen. Visible to the eye, while the display market to implement a display device, so if the pixel size of 70 microns or more are mostly very low density, so the relatively low performance belongs to the product family. These micro (μ) low-grade disposable electronic products / devices manufactured by the equipment, the printing process, a study using the technique began to receive the spotlight. Electronic industry, printing technology, innovation and competitiveness through technology development efforts underway in the process was accepted as a suitable technique such printed electronics has been created, a new concept, the technology and electronic components and circuits efforts to apply to the creation is increasing. Recently to cover the weakness of the etching, a printing method which use conductive paste is evaluated for the alternative and they are applying the screen print method instead. The strength of the screen printing method is low initial investment expense and simple printing stage so it has an advantage to make bulk production. In this study, flexible and strong adhesive on the ITO film has excellent electrical conductivity, were prepared by Ag Paste. Screen printing conductive patterns formed. Ag powders used flake-type. As a binder resin were manufactured using polyester resin and epoxy resin paste and dispersibility, Printability, electrically conductive adhesive film for evaluation.In this study, thermal curing after printing Screen printing manner (130℃ 10minute).
