Abstract
When a component is replaced or replenished in a predetermined feeder, mounters 3A and 3B refer to mount data in accordance with the feeder number for the feeder and read out the mounting position of the replaced or replenished component. The mounting position data is transmitted to a substrate inspecting apparatus 5 together with the substrate identification code of a substrate first processed after reel replacement. When the substrate corresponding to the substrate identification code is supplied, the substrate inspecting apparatus 5 refers to substrate inspection data in accordance with the mounting position data, specifies a component to be inspected, and executes the mounting error inspection according to character-string recognition for the specified component. When a mounting error is detected in this inspection, the substrate inspecting apparatus 5 transmits no-good determination to the mounters 3A and 3B receiving information.
