摘要： A screen printing method and apparatus for printing a circuit pattern corresponding to that of a stencil (4), onto a print-object article (1) placed on an ascendable/descendable positioning stage (2), through moving a squeegee (5a, 5b) horizontally while the squeegee is pushed in on the stencil so that print paste (9) is printed to the article via the stencil. The squeegee is lifted to an extent of a push-in stroke, to which the squeegee has been pushed in on the stencil, and thereafter the article is separated away from the stencil by moving the stage downward. The board is classified into first and second areas (121, 120) where values of opening sizes of the stencil along a squeegee moving direction are smaller than and not smaller than a threshold, and a speed of the squeegee at the first area is made slower than that at the second area. Upon an occurrence of print standby time during a printing operation, the print standby time is measured, and at a resumption of printing with the print standby canceled, the paste placed on the stencil during the standby time is screen-printed, by moving the squeegee at an adjusted print speed lower than the reference print speed based on a relationship between the print standby time and a print time due to the adjusted print speed after the resumption of printing.

摘要： 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 (2111) having a screw portion (2122) inserted therein is rotated by a rotating device (230), so that a nozzle stopper (2114) 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.

摘要： A reflow soldering device extracts a vaporized component of a contaminative material, such as flux, from exhaust gas from a reflow furnace. The device includes a conveyor for transferring a circuit substrate, a heater for heating the transferred circuit substrate, a cooler for cooling the circuit substrate which has been reflow soldered by heater, discharge pipes and a discharge blower for discharging an exhaust gas at high temperature from the heater to the outside of the device, and a flux remover mounted in the discharge pipes which cools the exhaust gas to 70.degree. C. and below, preferably 60.degree. C. and below, so as to cause a vaporized component, such as flux contained in the exhaust gas, to become liquid or solid and to be removed.

摘要： A screen printing apparatus includes: a positioning stage for positioning an object and a plate arranged above it; printing squeegees which are moved horizontally on the plate for printing through the plate onto the object; a driver for moving the positioning stage; a horizontal driver for moving the positioning stage in two substantially perpendicular directions; a positioning controller for calculating a central position of a pattern on the plate from a reference position and the size of an outer periphery of the object, moving the positioning stage so that the central position corresponds to a center of the object. A carry-in conveyor is provided for feeding the object onto the positioning stage along a predetermined transferring direction, the conveyor being arranged away from the positioning stage and having a carry-in conveyor surface on which the object is placed before the object is fed onto the positioning stage. The carry-in conveyor surface is positioned within the same plane as an object placing surface of the positioning stage. A carry-out conveyor is provided for transferring the object on the positioning stage along the transferring direction, the carry-out conveyor being arranged away from the positioning stage and having a carry-out conveyor surface on which the object is placed after the object is fed from the positioning stage. The carry-out conveyor surface is positioned within the same plane as the object placing surface of the positioning stage.
