Abstract:
A method for mounting an electronic component on a circuit board, the method comprising:moving a nozzle downward and sucking an upper surface of the electronic component;moving the nozzle and the sucked electronic component to a position over the circuit board, and moving the nozzle to a lowermost position; andsetting an air feed start timing of a first air feed and a second air feed into the nozzle such that an interior of the nozzle is turned to a state of atmospheric pressure during a period from a time of the nozzle reaching the lowermost position to a time of the nozzle starting to rise in a direction perpendicular to the upper surface of the electronic component, thereby releasing the suction and mounting the electronic component on the circuit board, wherein the air supplied by the second air feed is supplied in an amount that is larger than the amount of air supplied by the first air feed.
