发明名称 ELECTRONIC COMPONENT PLACING APPARATUS AND ELECTRONIC COMPONENT MOUNTING METHOD
摘要 To provide an electronic component placing apparatus and an electronic component mounting method that can prevent a cold joint from occurring when an electronic component likely to cause warp deformation is mounted by means of soldering. In the electronic component placing apparatus for placing the electronic component 16 with a plurality of solder bumps 16a formed on a lower surface on a board, a film 7a having a film thickness distribution for transferring a desired transfer amount of solder paste according to a state of warp deformation to each of the plurality of solder bumps is formed in a paste transfer unit 24, based on the component warp information indicating the state of warp deformation in a reflow process of the electronic component. Thereby, it is possible to prevent a cold joint from occurring when the electronic component likely to cause warp deformation is mounted by means of soldering by additionally supplying a just enough amount of solder to each solder bump 16a.
