Claim:
1. An electronic component mounting system that mounts electronic components at a plurality of electronic component mount positions including first electronic component mount positions and second electronic component mount positions on a substrate, to thus manufacture a mounted substrate, the system comprising: a screen printing device that positions a mask in which a plurality of apertures are formed to the substrate and that forms solder sections on electrodes formed at the plurality of electronic component mount positions on the substrate via the apertures; an inspection device that inspects the substrate on which the solder sections are formed and that generates inspection data including print displacement values of the solder sections at the plurality of electronic component mount positions, the print displacement values including a first print displacement value at each of the first electronic component mount positions and a second print displacement value at each of the second electronic component mount positions; an electronic component mounting device that mounts electronic components at the plurality of electronic component mount positions on the substrate having finished undergoing inspection in the inspection device; a feedback part that generates, based on the inspection data, first information about corrections on control parameters pertinent to positioning of the mask to the substrate in the screen printing device; and a feedforward part that generates, based on the inspection data, second information about corrections on electronic component mount coordinates in the electronic component mounting device, wherein the feedback part generates, based on the first print displacement value at each of the first electronic component mount positions, the first information about the corrections on the control parameters pertinent to positioning of the substrate to the mask, and the feedforward part generates, based on the second print displacement value at each of the second electronic component mount positions, the second information about the corrections on the electronic component mount coordinates in the electronic component mounting device, wherein each of the first electronic component mount positions has a higher degree of mounting difficulty than each of the second electronic component mount positions.
