Production unit including a printing device and upper and lower sealed chambers

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 Ecomprises: a rollerallowing a peripheral surfaceto approach one sideof a circuit board; moving meansfor horizontally moving the roller; rotating meansfor allowing the moving meansto rotate the roller; a squeegeerotatably supported along the peripheral surfaceof the roller; and printing pressure generating meansfor pressing the squeegeeto the circuit boardby a rotating reactive force of the roller
