The paste application device and paste application manner and the drawing Characteristic decision device in paste applying

摘要

P To provide an apparatus and a method for coating with paste in which drawing conditions can be set so as to obtain a proper drawing quality and to provide a drawing property determining device in paste coating in which the drawing property can be properly determined. PSOLUTION: The paste coating draws the paste and coats with the paste according to a drawing pattern by moving a coating nozzle while discharging the paste from the nozzle. The paste coating includes the steps of previously storing a drawing property index threshold value Kth showing a limit condition of bringing about a blur due to that the flowing speed of paste discharging does not reach the highest speed Vmax of the nozzle, comparing the drawing index threshold value Kth with the highest speed Vmax designated in the drawing and coating and the drawing property index K derived from the coating conditions including a nozzle horizontal moving time T and setting thereby the highest speed Vmax in a speed range in which a drawing fault does not occur.
