抄録	In this study, electrical and mechanical properties of the Cu filled polyurethane based electrically conductive adhesives (ECAs) affected by viscosity of the ECA paste were investigated. The viscosity of the ECA paste was controlled by adding different amount of diethyl carbitol as diluent. Significant difference could be observed in the electrical resistivity and shear strength joint of ECA by varying the viscosity of the ECA paste. The correlation between viscosity of the ECA paste and electrical resistivity and shear strength of ECA joint were studied, respectively. Result showed that reduced electrical resistivity and enhanced shear strength of ECA joint was observed following the decrease of viscosity of the ECA paste. Finally, polyurethane based Cu filled ECA with electrical resistivity at a magnitude order of 10-3Ω.cm and enhanced shear strength (above 17 MPa) was achieved.
