Latest Patents

Mitsui holds a patent for an electronic parts board and the method of producing the same. This invention involves an electronic component substrate that includes an insulating base and a flexible circuit board mounted on the insulating base. The flexible circuit board is a synthetic resin film that features terminal patterns and a conductor pattern, which is designed to slide in contact with a slider. The insulating base is a synthetic resin molded piece, and the flexible circuit board is insert-molded to the insulating base. The production process involves preparing the flexible circuit board and mold members that create a cavity corresponding to the external shape of the substrate. The flexible circuit board is then placed in the cavity, and molten molding resin is used to fill the cavity. Once the resin solidifies, the mold members are removed, resulting in the final electronic component substrate.
