Patent ID: 7246430

Claim:
An apparatus for mounting an electronic component onto a board, comprising: a board holding section for holding a board; a holding head for holding an electronic component; a load sensor attached to one of said holding head and said board holding section, said load sensor having two piezoelectric elements, stacked in a mounting direction of the electronic component when the electronic component is held by said holding head, for generating voltages upon receiving loads in two directions that are roughly perpendicular to the mounting direction and roughly mutually intersect each other, and for thereby allowing said load sensor to detect values of the loads in the two directions; and a mounting failure detection section for comparing a position in a two-dimensional space, in which the values of the loads in the two directions as detected by said load sensor serve as coordinate values, with a preset tolerance range in the two-dimensional space, and for thereby determining whether a mounting failure of the electronic component exists.
