Patent ID: 7571539

Claim:
A component verification method for verifying, by use of a computer, whether a component holder holding a plurality of components is correctly placed in a component supplying unit which supplies the components to a mounter, and wherein the component holder is placed in the component supply unit with an integrated circuit (IC) tag being attached to the component holder, the IC tag storing identification information for identifying the components held by the component holder, the component verification method comprising: a position specification step of specifying a placement position in the component supplying unit where the component holder is placed, based on a difference in position coordinates of each of a plurality of IC tags including the IC tag, the position coordinates being obtained based on a state of a signal received from each of the plurality of IC tags, wherein each of the plurality of IC tags is attached to a corresponding one of a plurality of component holders including the component holder; a read step of reading the identification information from the IC tag attached to the component holder, the IC tag having position coordinates corresponding to the placement position of the component holder specified in the position specification step; and a verification step of verifying (i) the identification information read out in the read step against prescribed component information for identifying a component that should be mounted onto the board, and (ii) the placement position specified in the position specification step against prescribed position information indicating a position where the component holder should be placed.
