Patent ID: 7356176

Claim:
A mounting-error inspecting method for inspecting whether a correct component is mounted on a component mounting substrate passing through a component mounting step, comprising: setting component identifying information for identifying a component and information for identifying a specific substrate on which the component is mounted when processing of replacing or replenishing the component is executed in the component mounting step; obtaining the component identifying information and substrate identifying information set in the component mounting step in an inspecting step on whether the correct component is mounted on the substrate, wherein a substrate corresponding to the substrate identifying information is specified among supplied substrates; executing the inspection step for the substrate; specifying a component to be inspected in accordance with the component identifying information; obtaining the image of the component to be inspected; extracting a character string from the image; and determining whether the component to be inspected is a correct component by comparing the extracted character string with a character string to be printed on the component to be inspected.
