Abstract:
A component mounting method wherein a component which is fed from a multiplicity of parts cassettes set in a component feeding unit is picked up successively by a component suction nozzle at a component pick-up position of the parts cassettes and is in succession mounted onto a circuit substrate, comprising the steps of:obtaining a predetermined value with reference to a pitch space between previously mounted components; measuring an amount of displacement of the component with respect to the component suction nozzle after the component has been picked up; informing that a parts cassette from which the component being held by the component suction nozzle is in abnormal condition when the measured amount of displacement of the component is larger than said predetermined value based on resultant data of measurement; and stopping a mounting operation for mounting the component of which parts cassette has been detected to be in abnormal condition.
