Patent ID: 7870991

Claim:
An electronic component mounting system having a plurality of electronic component mounting apparatuses connected for mounting an electronic component with a plurality of solder bumps formed on a lower surface on a board to manufacture a mounted board, said system comprising: a printing apparatus for printing the solder paste on the electrodes formed corresponding to said solder bumps on said board; a paste height measuring instrument for measuring the height of solder paste printed on said electrode and determining whether said height of solder paste is right or wrong individually for each said electrode based on the measurement result; an electronic component placing apparatus having a mounting head for taking the electronic component out of a component supply section and placing said electronic component on the board held in a board holding section, head movement means for moving said mounting head between said component supply section and the board holding section, and a paste transfer unit, disposed on a movement path of said mounting head, for transferring the solder paste to said solder bumps by causing the electronic component held in said mounting head to descend to a film formation face on which a film of solder paste is formed; and a paste transfer determination section for determining whether or not the transfer of solder paste by said paste transfer unit is required, based on the right or wrong determination result of said height by said paste height measuring instrument.
