The present invention provides an electronic part installation system capable of restraining the reducing of the production efficiency. The system comprises a substrate movement device configured to move the substrate according to the path in parallel to a first shaft in a specified surface and stop the substrate at a plurality of stop positions at the path; an installation head provided with a suction nozzle and a mark detection part capable of detecting identification marks of the substrate in a detection area; an installation head movement device configured to move the installation head in the movement range in the specified surface; a determination part configured to determine whether the identification mark of the substrate stopped at the first stop position at the path may be arranged in the detection area or not based on the movement range position information of the identification marks in the substrate; a generation part configured to generate temporary identification information of the substrate when it is determined the identification mark cannot be arranged in the detection area; an information processing part configured to store the trace information associated with the substrate provided with the electronic part at the first stop position and the temporary identification information in a relationship.
