Patent ID: 8881385

Claim:
A nozzle placement history data management method of managing placement history data of an adsorption nozzle in a mount head, the method used in an electronic component mounting apparatus for picking up an electronic component by vacuum adsorption from a component supply section with the adsorption nozzle detachably placed on the mount head and mounting the electronic component on a board, wherein: the electronic component mounting apparatus comprises an identification information read section for reading identification information given to the adsorption nozzle, an identification information storage section for storing the read identification information, and a nozzle presence/absence detection section for detecting the presence or absence of the adsorption nozzle in the mount head, and the nozzle placement history data management method comprises detecting that the adsorption nozzle is once removed and then is again placed by a machine operator based on the detection result of the nozzle presence/absence detection section, wherein if again-placing of the nozzle is detected, the identification information read section is caused to perform read operation of the identification information and newly read identification information is written into the identification information storage section for update.
