1. Field of the Invention
The present invention relates to a method of producing electrically conductive anisotropic heat sealing connector members, particularly which can cope with fine pitches of circuits patterns.
Such connector members or connector member will be referred to as "connector members" or "connector member", hereinafter.
The connector members are used for connecting the electrodes of liquid crystal display tubes, electrochromic display (ECD) panels or solar cells to the substrates of printed circuits and for connecting the terminals of the printed circuits to each other.
Such connector members are used in broad fields of use, such as, electric or electronic devices, chronometers, cameras, word processors, and computers, and the like.
2. Related Art Statement
Conventional electrically conductive anisotropic heat sealing connector members have electrically conductive anisotropic fillers 11 in the electrically conductive circuit patterns on a substrate film 1 and the remaining portion of the substrate film 1, as shown in FIG. 6. Because the anisotropic fillers 11 are existing on the remaining portion of the substrate film 1, as regards the electrical conductivity of the substrate film 11 in y direction, the weight proportion of the anisotropic fillers 11 can not be increased without damaging the electrical insulative property of the substrate film 1 in x direction.
