Abstract
A method of producing electrically conductive anisotropic heat sealing connector members comprising, a process A of preparing an electrically conductive anisotropic suspension liquid type paint, applying the conductive paint on a surface of a flexible electrically insulative substrate film to form an electrically conductive circuit of longitudinal thin stripes pattern, and drying the applied conductive paint on the substrate film; a process B of preparing an electrically insulative heat-bonding suspension liquid type paint, applying the insulative paint wholly on the surface of the substrate film including both the longitudinal thin stripes pattern formed by the process A and the remaining portion of the substrate film, and drying the applied insulative paint on the substrate film to form a press heat bonding layer; and a process C of severing the applied and dried substrate film prepared by the processes A and B to desired length and width sizes to produce electrically conductive anisotropic heat sealing connector members.
