Abstract

New metal powders containing organic thin film layer with multi-functional properties are prepared and used in the manufacturing of anisotropic conductive film (ACF) material for electronic package application. The organic thin film layer possesses both insulating property and thermo-compressed flowable property. The former insulating property ensures metal powder to have good insulation property at room temperature, and the latter thermo-compressed flowable property maintains the electric conductance of ACF material after high temperature compression process. Besides, the organic thin film layer also exhibited good steric hindrance to enhance the dispersion and anti-settling of metal powers in resin matrix. The functional organic groups on the surface thin film will also improve the interface adhesion between metal powder and resin matrix. Such metal powder with surface chemical modification is suitable for electronic material application, for example, anisotropic conductive film (ACF).
