    摘要: In a printing device in which a printing material is printed on or applied to a to-be-printed surface of a circuit board through a screen mask for printing having openings formed therein in a predetermined pattern, it is intended to reliably remove cream solder remaining in the openings in the screen mask. After an air suction mechanism (19) has its flow rate controlled by a flow rate controller (20). An air suction section (15) is lifted until its front end contacts with the screen mask (5), the air suction mechanism (19) starts cleaning by sucking air from the openings (6) in the screen mask (5). An inspecting camera (2) is used to observe the cream solder (4) remaining in the openings (6) after cleaning, and the air suction flow rate is controlled according to the results thereof to effect cleaning again.

    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.
