Mounting board manufacturing system

A mounting board manufacturing system comprising:

• a component placing device that executes component placing work for placing a component on a board;
• a library that stores a plurality of component data, each of the plurality of the component data including a plurality of control parameters for executing the component placing work by the component placing device and information regarding the component;
• an operation information counter that counts a score of the component placing work for each of the plurality of component data, wherein the score includes a success rate of the work executed by the component placing device;
• a learning unit;
• a learning data set storage that stores learning data set for each component data, the learning data set including a plurality of patterns combining the component data and the score based on a correction history;
• and
• a corrector that selects correction component data from the plurality of the component data based on the score of each of the plurality of component data and corrects one of the plurality of control parameters of the correction component data,
• wherein a new pattern is created in the learning data set when one of the plurality of control parameters is changed by an operator or the corrector, and
• wherein the learning unit learns a degree of influence of the plurality of control parameters on the score for the component based on the plurality of patterns in the learning data set.
