In a work system for substrates 10 which includes plural working machines 12, 14, 16, 18, and 20 conveying circuit substrates through two paths and in which the circuit substrates are conveyed through the two paths from the working machine disposed upstream out of the plural working machines to the working machine disposed downstream, a circuit substrate of which the work result is not good is conveyed to the downstream working machine earlier than the circuit substrate of which the work result is good in a state in which the circuit substrate of which the work result is good and the circuit substrate of which the work result is not good are able to be conveyed to the downstream working machine 20 by the upstream working machine 18. Accordingly, it is possible to perform work on the circuit substrate of which the work result is not good earlier and thus to enhance work efficiency of the work system and the working machine. |
