Abstract
A device for applying flux to the rear of a printed circuit board loaded with electronic parts on the front thereof and being transported by spraying the flux. The device has a single nozzle which is movable in a reciprocating motion in a direction perpendicular to the moving direction of the circuit board, thereby applying flux to the entire rear surface of the circuit board in a uniform distribution. The range of reciprocation of the nozzle is controlled on the basis of data generated by a sensor which is responsive to the width of the circuit board in transport. A flux feeding device capable of adjusting the amount of flux to be sprayed from the nozzle and a device for preventing the nozzle from being stopped up are associated with the flux applying device.
