Abstract
A method and an apparatus of inspecting a substrate with a component mounted thereon, which are capable of inspecting whether the component is properly mounted or not without additional setting or changing inspection condition, are provided. The method comprises measuring a three-dimensional shape by irradiating the pattern image toward the substrate through at least one illumination unit and by taking a reflected image through an imaging unit, extracting a shield region from the three-dimensional shape, and inspecting a component mounting defect in an area excluding the shield region in the three-dimensional shape.
