Abstract
A mounting device comprises a recognition mechanism and a control unit. The recognition mechanism recognizes a chip recognition mark and a substrate recognition mark through a mounting head and from above the mounting head and is movable in an in-plane direction of a substrate surface of a substrate. The control unit is connected to the recognition mechanism, calculates an amount of misalignment between a chip component and the substrate from position information about the chip recognition mark and the substrate recognition mark obtained from the recognition mechanism, and performs positioning by driving the mounting head and/or the substrate stage according to the amount of misalignment. The recognition mechanism has a chip recognition sensor for recognizing the chip recognition mark and a substrate recognition sensor for recognizing the substrate recognition mark provided independently so that focal positions thereof are different via a common optical axis path.
