| Abstract Scope |
The electrical properties of the conductive pastes are determined by the contact state of the conductive phases in the paste, which is affected by various factors such as the ratio of binder resin, solvent and conductive particles, the type of organic film, and environmental changes. In the present study, the change in electric resistivity of conductive pastes including Ag particles coated with various higher fatty acids were measured in-situ during the curing process. The electric resistance of cured Ag-paste was also investigated under the bending load. The electric resistance of the paste began to decrease at lower temperatures when the molecular weight of the organic film covering the Ag particles was smaller. In addition, the electric resistance decreased even below the thermal decomposition temperature of the organic film, suggesting that the film at the interface between the Ag particles became thinner during the heating process. |
