  • Publication number: 20150334839
    Abstract: The present invention involves forming wiring sections on a substrate capable of UV-ray transmission, and fixing a component to be electrically connected to the wiring sections onto the substrate using a UV-curable ACF. When doing so, fluidity in the UV-curable ACF is produced by applying pressure to the component, and UV rays are directly projected from the surface of the substrate even onto the UV-curable ACF areas shielded by the wiring sections. The UV-curable ACF is made to be fluid by applying pressure to the component after increasing fluidity of the UV-curable ACF by heating.
