PURPOSE:To obtain a uniform solder printing thickness even if the viscosity of cream solder changes by detecting the pressure to be exerted on a squeegee during movement and controlling a squeegee driving part in accordance with the detected pressure so as to maintain always the specified pressure to be exerted thereon. CONSTITUTION:Cream solder 16 is printed on a printing material 10 through a printing mask 12 by moving a squeegee 14. The pressure exerted on the squeegee 14 is detected by a sensor 20 during the movement of the squeegee 14 and the detection signal of the sensor 20 is inputted to a control part 22 which controls a squeegee driving part 18 to maintain always the specified pressure to be exerted to the squeegee 14 thereby regulating the moving speed of the squeegee. The uniform solder printing thickness is thus made obtainable even if the viscosity of the cream solder changes. |
