  • Patent number: 10237981
    Abstract: A method of manufacturing a mounting substrate includes a provisional pressing process, a driver pressing process, and a flexible printed circuit board pressing process. In the provisional pressing process, a driver and a flexible printed circuit board are provisionally pressed. In the driver pressing process, the driver is thermally pressed with a pressing head having a driver pressing surface and a flexible printed circuit board pressing surface, and pressure force is applied to the driver with elastically deforming a buffer. In the flexible printed circuit board pressing process, the pressing head is moved closer to the glass substrate such that a height level of the flexible printed circuit board pressing surface with respect to a mounting surface and a height level of the driver pressing surface with respect to the mounting surface are same and pressure force is applied to the flexible printed circuit board with elastically deforming the buffer.
