  • Printing method and printing apparatus
    Patent number: 6453811
    Abstract: Regarding filling of a paste, a temperature gradient at a paste-pressing face is managed by a heater incorporated in a filling head. Alternatively, a nonvolatile component is applied to a printing face of a base material before the paste is filled, thereby preventing a volatile component of the paste from evaporating with time. Viscosity of the paste is thus maintained. Meanwhile, a change of the quantity of the paste is coped with by changing a moving speed of the filling head or a contact angle of the filling head to the printing face, or by supporting the filling head at the side in touch with the printing face.
    Type: Grant
