제목 Effects of Particle Size Distribution on Sintering Properties of Silver Coated Copper Paste
초록 Conductive paste has been widely used as an electrode with the form of thick film. Among the other materials, silver is an admiring material to produce the highly conductive and stable layer through a facile sintering process in this thick film technology. However, the demands of alternative metal based conductive paste are increased for the industrial application due to the price competitiveness. Although copper can be easily oxidized, this low cost metal can be a promising candidate for the purpose of the conductive filler. In this study, the conductive paste was prepared using silver coated copper particles. Particularly, in order to examine the sintering properties of the paste at below 890oC, several pastes composed of different filler size distribution were investigated. As a result, it was found that the sheet resistance and shrinkage of the conductive thick film were strongly related to the densification by the size distribution of the silver coated copper paste.
