Patent ID: 8527082

Claim:
A component mounter that mounts a component on a substrate, said component mounter comprising: a mounting unit configured to mount a predetermined component on a substrate, the mounting unit being configured to repeat the mounting; a determination unit configured to determine whether the predetermined component is a first predetermined component or a second predetermined component, the first predetermined component requiring a high accuracy in the mounting and including a fine component and a component with a narrow lead pitch, and the second predetermined component requiring, before mounting the second predetermined component, confirmation of a status of a region in which the second predetermined component is to be mounted on the substrate; and an inspection unit configured to, (i) when said determination unit determines that the redetermined component is the first predetermined component, inspect a mounting status of the first predetermined component after mounting the first predetermined component, and (ii) when said determination unit determines that the predetermined component is the second predetermined component, inspect the status of the region in which the second predetermined component is to be mounted on the substrate, before mounting the second predetermined component to determine whether the region is acceptable for mounting the second predetermined component, wherein said mounting unit is a mounting head configured to mount the component on the substrate, said inspection unit is an inspection head configured to inspect the substrate, said mounting head and said inspection head are configured and arranged to alternately move above the substrate to perform mounting or inspecting, an operation time period required for said mounting head to mount the component on the substrate being longer than an operation time period required for said inspection head to inspect the substrate above the substrate, and a home position of said mounting head and a home position of said inspection head are set to satisfy a relationship that a distance from the home position of said mounting head to the substrate is equal to or longer than a distance from the home position of said inspection head to the substrate.
