Abstract
The present invention aims at providing an electronic component mounting apparatus and an electronic component mounting method that perform automated setting of a thickness of a paste film. The electronic component mounting apparatus of the present invention has a paste transfer unitthat horizontally, relatively moves a squeegeeand a transfer surfacewith respect to each other, thereby spreading, over the transfer surface, a paste filmwhose thickness is equivalent to the height of a squeegee gap 'c' formed from clearance between the squeegeeand the transfer surface; a storage unitthat stores a database defining correlation among bump heights, paste types, and squeegee-gap heights; a computing unitthat derives, from the database, a squeegee-gap height Gin correspondence with a height Hof a bump of an electronic component to be mounted and a type Pof paste to be transferred; and a vertical movement mechanismthat adjusts the height of the squeegee gap 'c' formed from clearance between the squeegeeand the transfer surfaceto a derived squeegee-gap height.
