Patent ID: 7793817

Claim:
An electronic component placing apparatus for placing an electronic component with a plurality of solder bumps formed on a lower surface on a board, comprising: a component supply section for supplying said electronic component; a board holding section for holding and positioning said board; a placing head for taking the electronic component out of said component supply section and placing said electronic component on the board held in said board holding section; head movement means for moving said placing head between said component supply section and the board holding section; a component warp information storage section for storing the component warp information indicating a state of warp deformation in a reflow process of said electronic component; a paste transfer unit, disposed on a movement path of said placing head, for transferring the solder paste to a plurality of solder bumps by forming a film of solder paste to be transferred to said solder bumps on a film formation face and causing the electronic component held in said placing head to descend to said film formation face; and a control section for controlling said paste transfer unit; wherein said paste transfer unit has a squeegee, driven by a squeegee drive section, for performing a film formation operation of combining the horizontal movement and the vertical movement on said film formation face, said control section controls said squeegee drive section based on said component warp information to form the film having a film thickness distribution for transferring a desired transfer amount of solder paste according to said state of warp deformation in said electronic component to each of said plurality of solder bumps.
