ABSTRACT:
A printing device, a production unit and a production method of electronic parts suitable for production of precise electronic parts are provided. A squeegee is attached to a rotating machine, and is autorotated and self-driven, and moreover, a printing pressure is generated in the squeegee, and resin is strongly filled, thereby achieving a print having a precision-shape. Further, with a perforated plate as a boundary, upper and lower chambers are provided so as to control a pressure, thereby performing cutting and dispensing of the resin and achieving a print having a precision-shape. This method is applied to the packaging of electronic parts. A printing device E1comprises: a roller3allowing a peripheral surface32to approach one side21of a circuit board2; moving means4for horizontally moving the roller3; rotating means5for allowing the moving means4to rotate the roller3; a squeegee6rotatably supported along the peripheral surface32of the roller3; and printing pressure generating means7for pressing the squeegee6to the circuit board2by a rotating reactive force of the roller3.
