Patent ID: 7299539

Claim:
An apparatus for mounting a component onto a substrate, comprising: a component supply device for supplying a component to be mounted onto a substrate; a holder for receiving the component from said component supply device and holding the component; and a controller for (i) prohibiting said holder from mounting the component, when held by said holder, onto the substrate when said controller makes a judgement that said holder would make an interference with another component mounted on the substrate were the component held by said holder attempted to be mounted onto the substrate, and (ii) causing said holder to mount the component, when held by said holder, onto the substrate when said controller makes a judgement that said holder would not make an interference with another component mounted on the substrate were the component held by said holder attempted to be mounted onto the substrate wherein said controller is also for correcting a position of said holder relative to the substrate, when the component is held by said holder and said controller makes the judgement that said holder would make an interference with the another component mounted on the substrate were the component held by said holder attempted to be mounted onto the substrate, and (iii) prohibiting said holder, after the position of said holder relative to the substrate has been corrected, from mounting the component held by said holder onto the substrate when said controller makes a judgement that said holder would make an interference with the another component mounted on the substrate were the component held by said holder attempted to be mounted onto the substrate, and (iv) causing said holder, after the position of said holder relative to the substrate has been corrected, to mount the component held by said holder onto the substrate when said controller makes a judgement that said holder would not make an interference with the another component mounted on the substrate were the component held by said holder attempted to be mounted onto the substrate.
