Abstract
The object of the present invention is to provide an apparatus and a method for applying a viscous fluid whereby a constant application diameter is achieved through a simple operation without a Tact loss while a surface of a member to be applied can be less damaged. An adhesive application member ( ) having a screw portion ( ) inserted therein is rotated by a rotating device ( ), so that a nozzle stopper ( ) of the adhesive application member is prevented from interfering with a wiring pattern on a face of a circuit board. Moreover, the screw portion is rotated synchronously as well when the adhesive application member is rotated, thereby preventing the adhesive from being discharged out from the nozzle in consequence to the rotation of the adhesive application member. An application diameter can hence be uniformed. The rotation of the screw portion is controlled in accordance with a viscosity of the adhesive, thus achieving the application in a required application diameter through a simple operation.
