Abstract
A flux spraying system controls a flux sprayer to selectively spray soldering flux onto a printed circuit board (PCB) by a fixture. The fixture is disposed between the PCB and the flux sprayer, and comprises a plurality of openings corresponding to target areas of the PCB. The flux spraying system comprises a statistic module, a calculation module, and a control module. The statistic module records attributes of the fixture to determine spraying areas on the fixture. The calculation module calculates movement parameters of the flux sprayer, a movement length during a movement period and spraying segments of the flux sprayer, and spray duration of the flux sprayer based on the movement length during one movement period and the spraying segments of the flux sprayer. The control module directs the flux sprayer to coat the target areas of the PCB through the openings of the fixture.
